For about three months my HOB
refuge was working great. I had great growth with my macros (caluepra and chaeto) and my nitrates always remained at either zero or at the most 5. Anyway, I went to check my water, which I normally dont do because it was stable, and my nitrates were around 30 and the macro stopped growing. Well I looked at my refuge and saw that the entire top of water level was just cyano
. My first assumption was that since their was so much cyano
at the top of the water that no light could get in for macro. Anyway, I removed the cyano
and trimmed up the macro. Do you guys think that was the reason for the non productivity or is it something else (I have been slacking on pwc
's). Any other suggestions? TIA........
