    Hi guys . anyone using seachem matrix for filtration. Seachem claims it helps with nitrate reduction...can anyone confirm this...or is it a possible that nitrates will go up...kinda like when ceramic noodles or filterwool is used

    I'm using about 6kg on my big system.

    Plus on my son's TL550, using about 2kg as only filtration option, except the skimmer. The TL550 is running from December. So far it looks good.

    So far I'm happy with the Matrix.

    Anaerobic = reduces nitrates
    Aerobic = reduces ammonia and nitrites.

    Its made for anaerobic, so if ammonia etc is 0 then its working, for nitrate reduction you have to make it low flow

    Essentially, no, as Dallas pointed out. Its simply a large surface area for aerobic colonization, "primary stages in the NO3 cycle)
    Surface area is huge, but for denitrification, as pointed out, you will need low flow. Determining the flow rate will be tricky, there are easier ways to achieve the deaired result.... Vinegar biocubes nopox prodibio bioplellets dsb etc etc etc
