can I ask you what "GSA" is?Increase Co2, more circulation and reduce the time lights are on. I went through the same problem at the beginning when trying to get everything to grow rapidly. I occasionally spot treat some GSA on my anubias and hair algae on moss with hydrogen peroxide...no harm to plants & livestock. Also, regular water changes will help.
Green Spotted Algae...very common on aquarium glass. I use a razor blade to scrape it off. Can't scrape if off plant leaves but hydrogen peroxide does the job.C
can I ask you what "GSA" is?
My plants are growing good, but with my new bulbs I'm starting to get some algae growth. Anything that can help? Lights are on for about 12 hours a day.
