I know his question is about algae, but I wanted to chime in about only feeding brine shrimp. Brine shrimp is very low in protein and should really just be an occasional snack (if used at all.) It's much better to use frozen mysis shrimp and/or cyclopeeze. With so few fish, you should cut a cube of mysis into at least 4 pieces (more if you can) and thaw one of the slices (most people rinse it as well.) Then add to the tank. No more than your fish can eat in 3 or 4 minutes.
