hi guys, I got a saltwater tank about 4 months ago but all I put in it was a few crabs and some liverock and sand. The sand is now completely covered in algae but I have not done anything else with it. I was wondering if anybody had suggestions as to what to do with the tank and where to get the fish. My current lfs does not have saltwater fish so I have to get them off the internet. Thanks for the help.
