Eheim SUBSTRAT Pro Biological Filtration Media Information
SUBSTRAT PRO 0.25L:
Eheim`s new superior biological media that improves and optimizes the performance of Ehfisubstrat. It is for highly active water purification with intensive biological decomposition of harmful substances. For use in all canister filters. Can be used in all applications like in any filter system, extra media for wet/dry sumps and in power filter media containers. It can also be used as a replacement media for the Eheim AquaBall. It is pH & KH neutral so it does not affect the water chemistry. It has a larger pore structure to ensure optimum bacterial colonisation and delays the silting-up of the pores (for much longer intervals between cleaning).
Biological Filter Media
A build-up of toxic nitrogenous wastes is a natural result of all aquarium inhabitant`s life processes. In nature, the body of water is large enough to dissipate or dilute these wastes. Some will even be converted into usable energy by living organisms. Within an aquarium however, without a powerful biological breakdown of these toxins, the fish literally poison themselves. This is the reason why biological filtration is the most desirable of all aquarium filtration.
This type of filtration is the purification of the aquarium water by using living organisms, such as nitrifying bacteria. These desirable bacteria will attach themselves to all hard surfaces within the aquarium system. They use the toxins as a food, converting harmful toxins such as ammonia and nitrite into less harmful nitrate. Nitrate can then be removed by performing regular water changes.
After prolonged use, mechanical and chemical filter media will act in a biological manner. They provide some surface area for bacterial colonization but this is actually very limited. In order to provide the greatest amount of surface area for bacteria colonies, filter media such as EHFISUBSTRAT or EHFILAV should be used.

Comments: Hello, just to let you know, I have only been using this proeheim for about a week. It probably isnt fair of me to give a review as of yet. The tank is a 30 gallon acrylic with at least 100 mollies all different ages and some swordtails. They procreate so frequently, that there really is way too many fish to fairly rate this product. I do think it will do better than the last eheim I bought, which I ended up tossing out for this same tank, once I thin out my "herd!!" (I will be doing this in the next two weeks. I plan to give them to a pet store to rehome them and then maybe I can give you a better review if you are still interested. Thanks for the inquiry.
Price VS Size

Comments: When I received the product my first thought was, "were's the rest" pretty small bag for such a high price. Otherwise the product is good for my Ehiem filter. The box is much bigger than the amount in it.

Comments: I have used this substrate in my Eheim wet/dry filters for several years and it works great. It's expensive but it does not wear out. I just bought some more to add to my eheim canister filter and my fluval fx5.
