The lightning for your aquarium

If you are fans of the aquatic world and the fish species and you want to have some in a homemade variety of pond, you must ensure that you will give the right conditions, for that it is necessary that you have at hand the best aquarium lamp on the market. So to have a well-kept aquarium in the house you should first measure the size, decide on certain types of lighting, and do a test of what you need, if you led aquarium lighting.

Led aquarium lighting:

  1. Led aquarium lighting during the night

Something fundamental to keep in mind is the day/night cycles in the aquarium. This is very important when it comes to preventing your fish from being stressed by lack or excess of light. Stresses makes fish sick or not develop properly. In nature, there is rarely total darkness during the night and that is why LED lights are used in the aquarium. They are quite economical and allow the fish to orient themselves and continue with their natural behavior at night. It has even been proven that many corals proliferate vigorously when you imitate the moonlight. We recommend that you use a timer to regulate the lights automatically.

  1. Led aquarium lighting during the day

For the day special lamps are used for aquariums. These emit certain wavelengths that are not present in the common lights. It will be very useful and interesting to start investigating what are the needs of the fish that you have in your aquarium. For example, species from forested rivers do not receive direct light in their natural habitat and, probably, you should light the aquarium for fewer hours than for other species. On the other hand, those who come from tropical regions or shallow reefs are used to direct sunlight for many hours a day and need it to live and develop, like aquatic plants. For corals, it is also essential to use actinic lights. The light on the blue side of the spectrum they emit has a wavelength that is easily absorbed by corals and their symbiotic algae during photosynthesis. These are led aquarium lighting with low intensity, so they are usually combined with other stronger lights.

  1. The colour temperature of Led aquarium lighting

The colour temperature, measured in Kelvin, expresses what colour of the spectrum predominates in the light emitted by each bulb. For aquariums lights, less than 5,500ºK are not used, since they encourage the growth of algae. An example of this type of lights is incandescent bulbs, which are not suitable for aquariums. Lamps between 5,500 and 6,500ºK are those used for freshwater aquariums with plants.

The 10,000ºK give a very intense white light with a bluish tint and are ideal for reefs or deeper freshwater aquariums. Finally, those of 20,000ºK emit a very strong and blue light that is recommended only for very deep aquariums and deep-sea fish. Actinic lights are not measured in degrees Kelvin because they are in the ultraviolet zone and are used only for reef aquariums, since they are important for the development of corals as well as highlighting their natural fluorescence.

  1. Types of lamps for aquariums

Lamp types are not as important as intensity or colour. This part depends exclusively on your taste and your budget since there are large price variations between them. The most economical are incandescent bulbs, although there are different colours, none goes beyond 2,700ºK (up to 3,000ºK for halogen). These lights give a yellow light and stimulate the growth of algae, in addition to generating too much heat. Its use is only recommended for small fishbowls.

  1. Fluorescent tubes for aquariums

The most commonly used lights are fluorescent tubes and only those manufactured specifically for aquariums are appropriate. They tend to be quite cheap, they do not emit much heat and you will find them in different colours. The most common tubes are those known as T12, T8 and T5, classified according to diameter. The first two use common ballasts, while the T5 require much more expensive electronic ballasts. The T5 has the advantage of being smaller, so you can combine more tubes in a small space and get more light intensity.

For very deep tanks or those that require a lot of led aquarium lighting, there are fluorescent tubes of high emission (HO – high output) or very high emission (VHO – very high output), with greater penetration in the water. These last less than normal fluorescents and it is difficult to get the artefacts to install them, which is why many fish breeders use Power Compact fluorescent lamps instead. They are smaller and use less energy to produce the same intensity of light. They are available in the same colours as the previous ones, associated with two or four tubes for the same connection. They are a bit more expensive, but they are still an economical alternative.

  1. Metal halide led to aquariums

Finally, the led aquarium lighting for aquariums that produce the brightest light at present is those of metal halide. They are very popular in reef aquariums because their light produces a reflection very similar to that of the sun on the water and they provide enough light for the demanding corals, clams and anemones. They have some drawbacks, such as its high price, as well as the artefacts needed to install them, which are specific to each voltage (ranging between 70 and 1,000 watts per bulb). Another problem is that they are delicate and you should not touch the glass with your fingers, as the fat of the skin weakens them.

They also get very hot when they are on and should be left to cool for at least an hour before handling them. Do not forget that at us you will find everything you need to light up your aquarium correctly with the best led aquarium lighting that will make your fish live happily both day and night.

Design of Silo-Shaped Sites

The silo structure is a web architecture designed to improve the SEO of a website. It has been used for more than a decade, although Spain has arrived somewhat later. And there is still discussion about its real effectiveness. Some say it is a great way to get relevant positions for highly competitive keywords, relatively quickly.Others say that it is often impossible to apply it, or that the results are not worth the effort.

In this article, we are going to collect everything we know about the silo structure and the main doubts about it. And we will update it with an own experiment with which we will prove its real effectiveness. The design of sites in silos is a concept coined by Charles Heflin of Seo2020 in his book “The Master Plan”. It refers to the way we should structure our sites to get more traffic not only for our “long tail” terms but also for more competitive terms, being seen as well as an Authority Site in a short time. Looking for Building a Web Site Using A Silo Structure?

We ask ourselves how to do so?

If you are new or experienced, you will have realized by now that search engine optimization is not a simple thing. The algorithms are constantly changing and making the famous updates that have harmed us or one of our clients more than once.

What should we pay attention to fir Building a Web Site Using A Silo Structure?

  • In a few words, we must rely on generating very good content.
  • Fresh and contrasting information.
  • Social networks: Promoting our links through social networks helps us to an organic positioning and attract interested visitors in our sector.
  • One of the most important parts of the optimization of a website is the architecture of the URLs in SILO. This is highly recommended for websites that specialize in a specific topic and want to get positioned on all the long tail terms.

What are URLs in SILO?

The URLs in SILO allow search engines to know better the content of a website. It is about the different levels of independent categories from the home and from each branch of subcategories and entries that can link to their same level or back, but would not link with the ramifications of different categories.

Example of URLs in SILO

If we see the graph of the definition, we imagine a web that goes about pets. For example, We would have a category of DOGS, the URL would look like this: pets / dogs

The URLs can link with each other and with the lower level (dogs), but not with / Cats, because it would not have to see. If the web is new we should modify these URLs to optimize them to the maximum, the problem is if we have been on the blog for a long time. To change it could be a problem even if we have redirects; it is convenient not to abuse them.

How do we change the default URLs in WordPress?

We can change the word “category” for another by entering Settings / Permanent links and writing a new base category. This work in the structure of our site must be done after the research of keywords and before starting to build something since it constitutes the skeleton. It is a very important part of the process of creating websites, and at the same time, it can be complicated to understand. How will it help us bring more traffic? Making it very easy for search engines to realize what our site is about. Google has introduced the concept of Latent Semantic Indexing, which judges a site for its relevance to a subject. We no longer speak of keyword density, but of subject density. The subject density is how many related words appear connected to the subject of a page that is considered relevant by the search engines.

The theme density cannot be done with a single page. You need a complete site that supports the theme density, through a correct link to the internal pages. For this, the best way is to use the silo structure. For example, on eBay we see a menu where he shows us his categories. Clicking on one, it shows another menu with all the sub-categories – a silo. And we can even reach another level until we reach the specific products page. Another example would be, each subdomain of them is a theme, and each item in your menu is a silo. Do you may have, learned till now about Building a Web Site Using A Silo Structure.

Confused? It is best to use an image that better explains the concept:

Building a Web Site Using A Silo Structure and organizing our site into a silo structure, you will improve individual pages within a silo, and the silo itself. This is a powerful factor to take advantage of 99% of other sites! This is how by playing intelligently we can master the niches (with quality content!).

How to organize our site in silos?

Each silo is a section of the page, so if your page is for example “video games”, one section would be Xbox 360, another PS3 another Wii, and so on. Each of these sections is a silo, a theme. The index will be linked to the entry page of each silo. Each silo page will link to the contents of that silo with a menu. Building a Web Site Using A Silo Structure is best as the silo is based on folders within your structure (they can be in subdomains, worse in folders is easier) and each silo has to have at least 5 pages to be considered a topic.

So, for example, your site, you will have your niche of PS3 in, and all the themes of ps3 will be inside this folder. In this way, you will have your related pages in such a way that search engines can easily find them and you will be rewarded. It is a concept that is also very helpful for visitors since they will find content 100% related to what they were looking for.

The Oldest Working Post Office in the World

Postal System

The Oldest working Post Office is situated in Sanquhar, Dumfriesshire, UK. It has been working consistently since 1712. The second most established working mail station is situated in Stockholm, Sweden (1720) and the third in Santiago, Chile (1772)

Sanquhar Post Office

Sanquhar Post Office:

Sanquhar post office started as an arranging post for mail carriages started about 300 years ago and has been in ceaseless administration since then. Eight years older than its closest opponent in Stockholm, Sweden, it is formally honored by both the Universal Postal Union and Guinness World Records. The branch is a well-known fascination for postal and stamp lovers, who visit to have their letters set apart with a hand-stamp bearing the legend: “The World’s Oldest Post Office.” Mr. Alam is the sixteenth person to run the branch and assumed control from postmistress Penny Murphy.

Sanquhar post office opened its entryway in 1712 in Dumfries along the High Street. It is recognized by the Guinness Book of Records as the oldest mail station on the planet. At the point when the mail station was opened, the postmen, who were called “runners,” kept running between officers to convey letters and packages. In 1738, the mail station started stamping sends and later acquainted steeds which were utilized with conveying letters and bundles. The mail station had no counters when it started its operations.

Operations of Sanquhar Post Office:

The letters were delivered through the window, where the clients are expected to tap the window and submit their letters along with the postal charges. The position of a postmaster was esteemed and was constantly held by men in other legitimate positions in the group, for example, executives, schoolmasters, and town agents. The mail station was modernized in 1974 with the substitution of the hand stamping by the hand-worked crossing out machine called bacon slicer. The historical backdrop of the Sanquhar post office has been formed by the group of Matthew Hogarth who maintained the business for a long time is as yet a committed client.

William Dalgleish, 75, vice executive of the Sanquhar Heritage Society, said that the post office worked distinctively in its initial days. There was no counter as we probably are aware them today. The mail was delivered through the window of the post office – you tapped on the window, delivered your mail and paid whatever charge was expected, and that is how it was finished. The role of a postmaster in society was viewed with respect, and as we stated earlier, a postmaster was always someone who held other respectable positions in the society.

The History of Mail and Postal System

Postal System

The first known usage of postal service is in Egypt in 2400 B.C. Kings of Egypt used postal service to send official orders throughout their territory. There is also proof of postal service used in ancient China, Persia, and India. The Universal Postal Union was founded in the year 1874. The Universal Postal Union incorporates 192 member nations. It is also responsible for setting up the rules and regulations for international mail exchanges.

At first, the envelopes are made of cloth and skins of animals. After the invention of papers, the postal system started using paper envelopes. China is the first country to invent and use paper envelopes.

A French man named De Valayer started a postal service at Paris, in 1653. He used to sell prepaid envelopes and deliver the letters in the mailbox if they are enveloped with his prepaid envelopes.

Postal service started using postal stamps in 1837. Uniform postal charges were started in 1840 through the efforts of Rowland Hill, a school teacher.

Postal System

The postal system works globally. Every postal service is connected with each other through the coordination of Universal Postal Union. These postal systems are now outdated when compared with modern fax and e-mail technologies. Postal systems are still the best mode of transmission for sending the personal handwritten documents to any location. Postal systems are still operating smoothly without the need for modern technologies.

Postal service in America:

Postal service was started in America during the colonial times to send and receive orders between England and American colonies. The first postal route in America was started between New York and Boston, which is now named as Route 1. After the establishment of centralized postal systems in the year 1693, The Governor of New Jersey was appointed as the deputy postmaster general. Benjamin Franklin developed the postal system by laying new roads and milestones on every route. He also started 24 hours mailing system between New York and Philadelphia.

Current status of postal system:

Almost every country uses the postal system embedded with local exchanging letters and official documents. In most post offices banking system has been started for rural areas and places with no banks. Governmental services and benefits are still delivered through postal service. In some rural areas in Africa medications and vaccinations are distributed through post offices.

Modern courier services have been started using the postal system. Courier services are both centralized and privatized. These courier services enable people to send parcels and covers to any place in the world. Though the internet has been developed to make sending emails and documents an instantaneous process, postal services are still used by many countries for their unique system.
