I'm running phosban to try and get rid of it. Driving my ferkin' nuts. I've been manually pulling it off rocks and powerheads. Been scraping it off rocks with a plastic knife and then using the net to capture free floating pieces.
I think some of those little green bubbles must have burst. They look like little green marbles--we talked about it on a podcast a couple weeks ago. I have the damn green bubbles all over in my tank. I imported them on some rocks I bought at the LFS several months ago. :grumble:
I guess I could just buy a sea hare and then reach in a pop a bubble once a week--that ought to keep the algae growing and keep him fat. :roll:
