Back for the first time in about a year, and I need some help urgently.
My sons tank broke about 4 weeks ago and I went out and bought him a new larger one (10 Gallons). Because I was going to have to put the fish straight in, I did all I could to get the tank right.
Here is what I did: The tank has a boxed, up-and-over filter which has ceramic rings in the end, and in the large compartment in the middle it had a big bag of carbon surrounded with filter foam. I replaced the carbon with well and truly matured ceramic media from my Eheim Ecco external pump. Put his fish in a bag and floated them in my tank (Juwel Vision 180). I then checked all my water levels twice, and they were: Ph 7.6, Ammonia 0, Nitrite 0, and Nitrates were 10. and filled his tank with water from mine. Checked the temp of his new water, re floted the fish in there, and then released them!
All has been perfect ( for a month) until Monday. His fish were all gasping, so I checked the water peramaters and they were: ammonia 0, Nitrite 0.50ppm and as for the Nitrates, they were about 100ppm!!!!
I did a 50% water change and added some Sera Nitrivec. I noticed lots of food waste in the tank, so Aidan has obviously overfed them. 2 days on and smaller water changes, the levels have not improved and he has lost 2 fish!!!!
What can I do?
