    Glad you solved the smelly situation - Slaphppy7

    I have a recently cycled FW 20 gallon tank lightly stocked with one male red wag tail platy, one silver lyre tail mollie and one female betta. After water changes, even large (70-80%) water changes, I can't seem to get my nitrates below 30-40 ppm. I have tested my tap water and I know that is the problem. My question is, if I used Purigen, which supposedly absorbs all ammonia, nitrites and nitrates, is it defeating the purpose of a natural nitrogen cycle or, since my nitrates will always be high, because of my tap water, is this a good idea ? By the way, I have only started to plant a few Water Wisteria and Java Ferns so I don't think that there are that many yet to help out reducing nitrates. Thanks.

    Actually, Purigen does not adsorb ammonia, nitrites, or nitrates. It adsorbs organic compounds that lead to the creation of ammonia which finally become nitrates.

    It will however, will only allow a smaller bacteria colony to thrive since the amount of ammonia being produced is less. Fish still excrete ammonia.

    If you use Purigen on your tap water that has nitrates, it will not remove the nitrates.

    from Seachem

    Purigen will remove organics before they can be converted by bacteria into ammonia, nitrite or nitrate, resulting in lowered nitrate concentrations over time, but it will not directly remove these chemicals from the water.
