    Hi All

    I have 3 tanks that are giving me challenges 2 have high No3 and one has high No2. These tanks have been running for 3 years and the water parameters have always been perfect but over the last few weeks they have been giving me issues. The 1 with high No2 has no fish in as it's my breeding tank and the other two tanks with the high No3 have live breeders in the one and Angel's in the other.

    Any advice would be appreciated

    High NO2 tank: when last did you have fish in there? The beneficial bacteria need ammonia (from fish poop) as food source so perhaps they starved and your tank is having to cycle all over again? Add Seachem stability for 8 days and a hardy fish or two.

    High NO3 tanks: could you give more info ito planting, stocking, feeding, filtration, any recent changes? Tank size etc

    And the actual values of Ammonia, NO2 and NO3 on the tanks. PH and temp would help also.

    Hi

    I will try the your suggestion for the no2 tank I haven't had fish in there for about 2 months but I have been doing water changes and putting backup in.

    The No3 tanks

    Tank 1:
    2ft tank with 4 Guppies, 3 Swordtails and 2 Platies
    temp is 25 degrees with floating hornwart.
    fish are fed a combination of flakes and Tetra Prima Granules. and filter is a air pump filter

    Tank 2:
    5ft tank with 10 angels (7 Zebra and 3 Albino)
    temp is 26 degrees with 2 Java Fern Windelov and a Jumbo Anubias
    Fish are fed Tetra Prima Granules and frozen worms

    I will take pictures when I get home I will also do another test and send results

    Cool send through the results and photos and am sure folks can help. Also how often and how much you feed.

    Also add Seachem Prime to detoxify ammonia and nitrites until the tank is cycled again and safe for more sensitive fish. Your 2 platys should do the job in the meantime

    Please tell us more about you filtration , maturity of the tanks/age. But sounds like the biological waste is way over the filters bio capacity. Thus not converting correct or quick enough. Please tell us about your maintenance schedule as well. Could also be an too clean tank.
