I have a 55 gallon tank with a 40 gallon planted sump and a 2+ cube per day algae scrubber, I am very comfortable that the scrubber is working correctly, I remove about 1.5 - 2 cups of algae ever 5 days or so. Since I got the scrubber a few months back my hair algae problem has disappeared. However my bubble algae is INSANE it has gotten worse and worse, it covers absoutely every surface that recieves even the tiniest bit of lite. I have triedlowering my light as low as it will got (about 5%) and left it there for weeks, I have tried everything from 8-12 hour light cycles, and I just tore the entire thing apart and removed every scrap of it that I could find, which was about 6 cups.
Anyone have any ideas outside the norm to get rid of this or slow it down? My scrubber is my only mechanical filter of any kind.
