red bubble algae..how to control/eliminate

[JPotter]

Thank you for the input. I don't think I have "dead zones" as I don't see debris accumulation and my rock set up is very open. My clowns have arranged my sand from zero to 1.5" depending on the area. I have the impeller return pump, a Nano propeller and a Koralia 1 propeller. The propellers are on separate timers to allow for (set up) varying patterns of chaotic flow. I scraped a lot of the algae off with a dental scaler (worked like a charm) and sucked up what I could catch with a baster (didn't work so well). I agree the tubastrea will be an ongoing issue. I plan to have extra water made up so I can transfer it to a small fresh bath to feed it..then through out the bath water and return the tubastrea to the main tank. It sounds cumbersome but once a routine I think it might work. What do you think? I also put in an Emerald crab but haven't seen it since the first evening The porcelain crab seems very content
