Hey fish gurus I need some help please!
So I have a 28 gallon freshwater tank that I have been cycling (fishless) for a few weeks and it was going great! Yesterday my ammonia =0ish, nitrites = 0 ish and nitrates = 20ppm. I was following a guide that said to do one last job...a huge water change (90%) and turn the heater down. So I did that.
Went to test everything one final time a day later and before adding some fish and hey presto! the nitrites are back to 20ppm!!! Did I kill my lovely nitrite gobbling bacteria with fresh water and prime? Can anyone tell me what I may have done wrong?And more importantly how can I fix it? I was soooo close to getting my fish!!!
Thanks Lynne
