How old is your tank? Adding too many new fish, uncured rocks, changing position of too many rocks at a same time,overfeeding or equipment failure can cause this. If your tank is new, then it is a new tank syndrome. Check your protein skimmer if u had.
Thankyou. I haven’t added any new fish within the last week so don’t think it’s that. Tank has been running about 6 weeks so fairly new. Only thing I can think that I’ve done different is turn on the protein skimmer and last night I turned it off? Could it because I turned it off?
Tank is about 6 weeks old. I have 4 fish.
Tank is about 6 weeks old. 60litres a few fish not many. I feed twice a day. I use salifert tests. Yesterday the ammonia was very clearly 0. Today very very clearly almost 2! Only thing I’ve done different is turn my skimmer on and then a day later turn it off as I didn’t think it was working properly
Are the 4 fish recent additions? All at once? I’m assuming the tank cycled somehow? Double check the method on the test kit and follow it word for word. A tank pic would be nice, perhaps even a pic of the test against the ammonia colour card.
Fishing for clues. This sounds like a testing error but let’s check. By the way, if the system has measurable nitrite, it interferes with the nitrate test, so don’t bother testing nitrate.
Thankyou. I didn’t retest as I had to leave for work. I have 4 fish in there and a CUC. Only thing I’ve done different is clean the inside of the glass last night (I’m at the ugly stage) and turn my skimmer off as I was unsure that it was working properly. I feed twice a day?
“Yo ammonia, I hate you irl. Go away. You aren’t wanted here.”
