cycle problem

75 gallon Fx6 filter One 5 inch ranchu goldfish I put biomedia from a cycled filter to the fx6, running it for 14 days in the cycled tank. I moved the fx6 to the 75 gallon. After 7 days i tested the parameters before a water change. Ammonia: .25 ppm The tap water had 0 ammonia. I admit ive...

Hey y’all! im having some trouble with my cycling here. I was doing great, ammonia was going from 2 to 0 within 2 days. However, I was over 100 nitrates, so I decided to do a water change, and for some reason thought it would be a good idea to add more ammonia than I usually do. Now (even after...

So I did a big no no..I decided I wanted to go to a bare bottom tank and removed all my gravel. I had plants and driftwood and replaced my 2 filters. Well I apparently got rid of a lot of my good bacteria because I had a bacteria bloom and the water got really cloudy. I did a 50% water change...

Hey everyone...Im perplexed and need some help. I have what I feel is more than adequate filtration, flow etc on a yr old established tank and Im still reading what I consider high nitrates for such small stock & large water column. I havent tested the water directly after a change (I will...
