This has probably been addressed so forgive me if I'm rehashing something, but I'm now getting purple hairy algae all over the sand, and green hairy algae on the live rock. We've had the tank up since the first of August and all has been well. We're not putting anything new in uless it's been quarantined and to date, have 2 chromis, 2 emerald crabs, a a handful (12-15) turbo snails and a couple of hermit crabs. Recently, the purple algae started growing like crazy on the sand/crushed coral and I've done two 5 gallon water changes in the last 2 weeks on this 74 gallon tank. How can I get rid of this stuff?
