Hi all, I am currently running a 20 gallon tank with acropora. This is the ONLY tank, out of 4 that I have kept so far, that given me an insane algae issue. I have diatoms, Green hair algae all over the rock a little more than a month ago. After treating it with flux rx and taking out my fine sand bed (since its never clean), the condition improved a lot. I was planning to refill the tank with crushed coral, as suggested by the guy at my LFS before, but now, I am wondering if I should just run a bare bottom for easier maintenance and change out the live rock slowly and use the Tonga branch rock if possible. Any advice and suggestions? Thanks
