Setup UV sterilizer - How to install a UV sterilizer

UV sterilizers exists in several designs. Due to this constructural differences, several setups for the installation of UV sterilizers exists. This article shows pictures which show for every of the installation the several components. Every type of UV sterilizers has advantages and disadvantages which are also be described for each type.

UV sterilizer with internal filter and pump

This type of UV sterilizer is an all in one solution. You have a internal filter, a pump and a UV sterilizer in one tool. The advantage is the reduced installation effort for installing such integrated UV sterilizer. In most cases the power supply is the only interface you have to deal with. No additional tubes are necessary. These kind of UV sterilizers are often very smal and compact and are the best solution for smal and new aquariums. If you have already a filter and a pump, these kind of UV sterilizer will double your equipment and destroy a lot of these advantages. Other disadvantages are that they are limited in their performance in the meaning of wattages. For larger aquariums you will not find not such kind of integrated UV sterilizers.

Installation: It is a plug and play system. Please read the manual instruction of the manufacturer. Normaly you only to bring the UV sterilizer into the aquarium and connect the power supply. Be carefully: Most of them have to be installed in the aquarium water, but one of them have to be installed outside the aquarium. In this cases they are no internal filters, they are external filters as described below.

UV sterilizer setup with external filter and pump

If you have an equiped aquarium and would like to install an addional UV sterilizer you have all fredom to choose an pure UV sterilizer. You have not to buy an additional pump becaus you can use the pump of the external filter to bring the water through the UV sterilizer.

Installation: The UV sterilizer should continue to be installed so that no air in the UV sterilzer can accumulate. Therefore the UV sterilizer should be installed edgewise. The inflow should come from below and the outflow should be located on the upper end of the sterilizer. You can optimized the installation by following to aspects: If possible install the intake and outlet ports of the UV sterilizers in the cross directions of the aquarium. This will also optimize the performance of the filter. The second suggestions is too bring the ports of the UV sterilizers in cross directions, which will increase the performance of the UV sterilizer itself. The following picture shows the principles of the two tricks.

Plant growth, iron and UV sterilizers

Plants need trace elements (incidentally, just as we humans) to live and grow. A trace element that is often discussed in connection with the use of UV clarifiers is iron.

As a metallic trace element, it is for aquatic plants only in a so-called chelate compound usable as it is only soluble in water so. The term chelate comes from the Greek word "crab claw". In iron fertilizers are salts often assume the function of the "crab claw". One can easily imagine that, in the "crab claw", the iron in the water is soluble. The water solubility is a prerequisite that the iron can be transported to the green cells of aquatic plants. But, the "crab claw" to the iron again to share, because it can only be so excluded from the plant. The release is usually done by the natural UV content of the aquarium light. Since the dissolved in water and protected by the "crab claws" iron compound enge also flow through the UV sterilizers, these are also irradiated by UV-C light. This additional UV light accelerates the destruction of the "crab claws" and the uncovering of the iron. The effect is similar to the destruction of the DNA of the cell nuclei, only in this case it is an undesirable effect. The iron content of the water drops is usually faster to 0 mg / l as without the use of a UV sterilizer. The problem arises when it comes to lasting iron deficiency and (insert link, Google Search) aquatic plants iron deficiency show. What can be done to prevent the iron deficiency to be expected? The fertilizer industry has recognized the need and particularly UV-stable chelators developed. Our recommendation is to use these specific products with the use of UV sterilizers. The UV-stable manure are not significantly more expensive than conventional water plant fertilizer, so it is worth, here select the right product.
