    Water changers 25% weekly with gravel clean too. fine Filter wool changed weekly and filter sponges rinse as needed, no more than, mthly.
    Ammonia 0
    Nitrate a whoppin 50 on Nutrafin testing
    Nitrite 0.8 at least.
    What am I doing wrong.
    I'm guessing I'm have a mini cycle or something, but why. Am I cleaning gravel too much?
    Gonna do a big water change today. Cos I'm panicking.

    What do you have in the tank? I don't change my fine filter wool even monthly. It spikes my nitrites. I rotate changing anything and keep it few and far between. Can't you rinse the wool?

    I never thought of rinsing the wool. I thought I was meant to chuck it and renew.
    Tank has 5 gourami, small zebra plec, super red bristlenose plec, 4 harlequins, 2 corys and 2 pictus catfish
