I have a 29g biocube, with 29 pounds of live rock. It has been running for about 2 months and ammonia, nitrites, nitrate, ph, and phosphates are all at a good level. I'm still getting brown algea and a little green on the walls and sand. What give? Need help. The fish seem to be doing fine. I have 2 damsels, and one tomato clown, scooter blennie. One emerald crab, about 15 snails ( just added yesterday, the snails that is) I'm not sure how to stop this problem. I'm using pre-mixed saltwater, which is RO water, that I buy from Adam at Partners Pets in Round rock. Any advice is welcome.
Thanks.
