    Sick Guppy?

    Hello, my guppy has been acting strange lately. We have recently moved him to a new tank that was, as far as I’m concerned, cycled or almost cycled as it was used and there was good bacteria in the filter media, gravel, decor, surface, etc. and we also used a bacteria starter for a couple days...

    Some technical advice about Ammonia and Nitrites

    Three of my 4 tanks were all cycled beautifully and according to directions on this website using Ammonia. It usually took 5-7 cycles of ammonia before I could get 2 days in a row of 0's in all the right places. Where I deviated was to adjust the PH down with PHdown before fish were added. Our...

    Will a water change and replacing filter uncycle the tank?

    My 10 gallon tank is cycled as of 2 months ago. I have been using the same filter pad for the same amount of time, and I have always rinsed it off with used tank water as advised to prevent what would un-cycle the tank. Unfortunately, no matter how many times I rinsed the filter pad the...
