Over the past month or so I have been getting brown and light green algae over pretty much everything in my tank, glass, and very thick brown algae on my live rock. I haven't changed anything. Phosphates have always been 0.5 in my tap water (I am waiting on my ro system in the mail to change that) my hardness is also about 16 which is why i just bought an ro system. My temperature has been varying +/- 4 degrees about 76-80 due to the weather lately. Nitrates are 10 or less. I have been changing out my bio balls and replacing it with live rock rubble in my canister over the past month about a 1/4 at a time. Could this be my tank cycling again because of the exchanging of bio balls? Thanks you guys are always great and very knowledgeable.
