I have a 5 gallon tank that is having ammonia issues. The lfs thought the issue could be tetracycline used to treat an infection. They thought it might have zapped all the good bacteria with the bad. Hence the .5 ammonia levels before and after water changes. I treated with prime as a temporary fix. Today I went back to lfs to have the water tested. They also gave me a bag full of muck squeezed out from one of their filters to seed my tank.
So I soaked my filter in the muck and then poured it all in the tank after I did a 50% water change (previous water change was 50% 24 hrs ago.) So my water is starting to settle and get less cloudy, but now I have all the muck settled at the bottom of the tank. How long should I leave it before vacuuming and doing another water change? I don't want to"clean up"the good bacteria from the lfs, but it also looks sort of nasty;)
FWIW the lfs suggested 50% water changes weekly till the tank cycles. I am currently treating for fin rot (which the lfs thought might be ammonia burn) since he had such drastic fin loss in a 24 hr period with Maracyn Plus (lfs said it would be easier on tank cycling and good bacteria.) I have a 5 gallon tank, heated at 80, internal tom filter, three live plants and a zebra snail.
