Lots of snails including sand sifters, and hermits. My last tests showed my alk was low (6). I don't have any other algae issues, I think the branching stuff came in in a coral frag. Any other suggestions, Im not sure if it's over feeding as I'm careful. What else should I be looking for?

Whats in the canister filter? What media are you running? And when was the last replacement of media?

Maybe cut back on feeding to everyother day and make sure you rinse all frozen foods as they are loaded with phosphates
