I'd steer clear of any quick fix algae treatments. I'm a big fan of large frequent water changes. You've got some phospates loading up somewhere. Try water changes and cutting your lighting a few hous a day and see if that helps. Also is your tank in dirrect sunlight because that can cause some issues as well? This is also assuming your using RO/DI for top-offs.
Agreed. The only true cure for algae issues is to solve the source, which is phosphates. There are several ways to cure the phosphate issue... waterchanges being the predominate one (as long as the source water is RODI or Distilled and not Tap)...
I have addressed all those issues and I never can measure any detectable phosphate level, I'd just like to see about getting it killed and then starting "fresh". I wonder if these products that say they are reef safe are actually reef safe.
Most home aquarium phosphate tests are useless they dont test for the right kind of phosphates. I'd say if thats what you wanna do go for it. There are alot of products out there that claim to be reef safe that arn't. The golden rule is you dont put anything in your tank you cant test for. If your rock is totally infested I'd cook it and start over.
phosphates are the food for algae...
remove the food (phosphates) and you are heading in the right direction.
1. frequent water changes w/rodi until the algae is gone
2. high quality frozen food rinsed well in order to remove --- Phosphates
3. good skimmer
