Before I even start telling u ALL my problems with this tank, I know I've done a few things wrong and you'll be like Ahhhh,eeekkkk, no she didn't! Well yes, I did. Alot of mistakes. Now I need allying wisdom and advice and experience of fix it. Please!!
Ok...new tank, new filters/gravel, everything brand new. 3ft, 175L (bout 47gal) running about 9 weeks.
Was started with 2 goldfish where ammonia was about 0.25. At about week 3 I was given a bunch of random fish that I put in and since then...well u can imagine. I have had quite a few deaths and now have about 20 fish in the tank. Currently levels are
Ammonia: around 8ppm (I know!!!how are the fish alive)
Nitrite: around 1ppm
Running an undergravel filter with powerheads and two 800l/hr internal filters (currently sponge only due to meds)
I have been doing regular water changes but even after a 50% and a 25% two days later the levels didn't drop at all. I've been dosing prime with the water changes and had to treat for ich last week (tri sulpha). I can't figure out why the levels won't drop!! Have read lots that ammonia suppresses growth of nitrite bacteria and so can adding detoxifyers like prime. Can't believe these fish are still alive, need HELP! Know I didn't start off right but where to I go from here??? Have tested tap water its 0 for ammonia and nitrites.
