I'm setting up my first SW aquarium. Its a 29gal FOWLR. I was thinking about getting a percula clown, scarlet/flame hawkfish, and a lawnmower blenny. One of the things I wanted to know is about not using RO water. From what I've heard, the basic problem with this is algae. Is there anything I can put in the tank that will eat the algae fast enough to keep it gone? Will the blenny eat hair algae? Also, I want to get a cleaner shrimp. I've heard that the hawkfish will eat the shrimp. Is that correct? Also for food, I have no source to get live food, frozen food I think I could possibly get off the internet. I'd like something that will eat flakes or pellets. I could also get marine algae over the internet I think.
