What is the best way to remove the hair algae in my GSP? I have tried blowing it out without success. I noticed it the other day when had a power failure for about an hour, it closed up showing it. It is now swaying in the current as shown in the picture. Not asking how to treat the whole tank for it, it's disappearing more now that UV is back on. Showed up during PraziPro dosing. Just asking how to remove it from GSP without ticking it off.
