SeachemMatrix – High Capacity Biofiltration, States it controls ammonia, nitrite, and nitrate, but I have only really had concerns with nitrate, so can't speak to the others. High nitrate levels can encourage excessive algae growth, which can make the aquarium look unsightly. Unlike other nitrate reducing products, which need regular recharging and replacing, Tetra NitrateMinus is simply added weekly to the aquarium. Also unlike many ordinary nitrate reducing products, NitrateMinus does not need to be added to a filter system to work, but is simply added straight to the water. Tetra Nitrate Minus can be used for the long-term reduction and control of nitrate, leading to better water quality and less algae. long-term reduction of the nitrate level to below 40 to 50 mg/l (depending on the aquarium conditions)

All our electrical products carry a 12 month guarantee or longer if specified by the manufacturer. Products that carry a manufacturer’s guarantee can be returned, if faulty, to us for repair or exchange as necessary during the guarantee period.Tetra NitrateMinus is used to permanently reduce the nitrate content and biocide-free algae control in fresh and saltwater aquariums. Takes up alarge amount of filter space. I have itand my main filter media in my TopFin and Quiet Flow 10s, and basically almostno room for anything else. Items returned that are not deemed to be faulty or the fault is not covered under the guarantee will be subject to return postage costs.

SeachemMatrix – High Capacity Biofiltration, States it controls ammonia, nitrite, andnitrate, but I have only really had concerns with nitrate, so can't speak to the others.Matrix™ is ahigh porosity biomedia that provides efficient biofiltration for the removal ofnitrogenous waste. Matrix™ is a porousinorganic solid about 10 mm in diameter (a little larger than standard aquariumgravel). From what I can tell, itbasically provides a living space for the BB that would eat up nitrate. I added your con. Did you determine this is what caused your cloudiness issue? Were you using the original bag it came in? The water is not clarified mechanically by a filter system alone. Special bacteria are required for the conversion of ammonia to nitrate, which find a large space in a sufficiently dimensioned filter system. With the use of Tetra SafeStart, the aquarist creates optimal conditions for good bioactivity in the aquarium. A widespread opinion that predominantly the bacteria of the Nitrobacter group are active as nitrifying bacteria in the aquarium has been scientifically refuted. In natural biofilms from aquariums, Tetra Research was able to identify the bacteria of the Nitrospira strain as the predominant representative of the nitrite-reducing bacteria. The ammonia, which is also very harmful to the fish, is broken down by bacteria of the genera Nitrospira and Nitrosomonas. The latest discoveries in microbiology ultimately led to SafeStart's product development. Optimal conditions for the settlement of these important bacteria are achieved with Tetra Bactozyme. It covers all surfaces with a bacteria-promoting biofilm on which nitrifying bacteria can develop. Tetra Biocoryn complements these products.
