My tank have been up and running for 3yrs. In the beginning I did not have any problems. Parameters were where they we supposed to be. I did water changes weekly. Everything was fine. No algae problems of any kind othe than bubble algae. I started using pappone and had to stop because I started getting crazy algae of all kinds. I have stoped using it and it's been about 3mos. I have hair algae on a piece of two of my rocks. Just a small patch here and there and also behind my Tunze. I don't overfeed and I am trying to trace the source of the algae. My fuge is fed from my tank. I was told not to mess with my fuge and any waste that's in there will eventually be broken down etc. I also have this hazy looking algae on my return spouts and on my upper rock. What's going on with my tank?
