I believe my tank has finished cycling. Last time I checked the ( on Friday ) amm. and nitrite were 0 and nitrate was 10 or less ( the test kit doesnt have a reading for 0 ). I thought that the red growths on the live rock were the start of coralline but when I came into work today I noticed that much of the rock was covered in a layer of red fuzzy growth which I believe might be some sort of nuisance algae. I will try to upload a picture tomorrow but I doubt it will be clear anyway. Can anyone tell me what this is and if it is a normal part of cycling? I wanted to add my cleaning crew tomorrow so help is appreciated.
