Algae " the bad stuff"

Always tricky to tell Cyano from Dino's without a pic.

I've used Chemiclean a number of time and never had any adverse effects.

Never in an sps tank though so can't comment on it's effects there.

I've used it several times, never an issue. I never understand why people don't use it. It's quick ,simple and done.

The only adverse effect I've noticed, if you can call it that, is it will put a skimmer into overdrive...

it is incredibly effective though.
