How often do you feed your fish?

[supersmile]

So do you think I should be adding another air pump to eliminate the algae as well as rinsing the mysis shrimp? I keep trying to syphon the algae off the rocks and sand but it seems it just comes back the next day. I don't want this stuff to start taking over my tank. I LOVE MY TANK. Can the lack of flow cause my sand to be dirty as well? Thank you everyone for your input. I greatly appreciate it!
