I have had my 90 gallon fish only tank set up for 4 1/2 months. I have a wet/dry filter with a filter bag. I have 5 snails, two hermit crabs, a bloodfire shrimp, two percula clowns, a royal gramma and a yellow tailed damsel. All have been healthy and I have not lost anything yet. I am having issues with algae. It started with brown algae. I purchased the snails and they take care of that except in the sand. They barely touch that. I also have a dark green algae that grows on my live(dead) rock skeletons and in clumbs in the sand. Are there animals I can add to the tank to help control the algae. It just looks so ugly and I rustle up the sand whenever I am having company so it looks better. I have been testing my water and everything looks good except my nitrates are around 20 ppm. Am I safe to add more fish? I have been trying to be patient but I would really like to add an angel, tang or butterfly. Thanks for any help/advice/guidance in advance.
