Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I run leds, and I have been increasing them slowly for the sps I have. I also bumped up flow on my bottom power head hopefully that starts to make a difference.
I just killed the sandbed on my 10g Xenia specific as it was causing cyano probs. But I never maintained it as its my 'what happens in the tank stays in the tank' tank.
Conversly, I churn the sand and blow off the rock in my 25g zoa tank every other day with a baster and it's pristine, no cyano concerns.
