Hi,
I've had my tank setup with 12 cichlids for the past month (yellow labs, afra coubes, demasoni) The tank is fully cycled. Amonia and nitrite are 0 and nitrate is 20-30
today i cleaned the filter for the first time but when I connected it all back, it started spitting out white fluff. I'm not sure what that is but the fish seem to be doing ok, the fluff settled down after some time and it's now clear again. Perhaps I didn't clean the filter properly. I used tank water to clean it.
The tank was used for cichlids before it was mine. I am wondering if it's maybe some old bacteria or something...
Has anyone seen this? What can I do to fix it?
Thank you.
