Hi all. After letting the GDA build up to try to let it go through it "spore cycles" what is the best way to remove it from the tank. Using a magnet scrapper on all that algae made the tank water build up with a lot of free floating algae real fast. Should I take the fish out so I can take out close to 90% out or should i leave them in and do multiple changes by diluting the free floating Algae with new water while changing (which will obviously take alittle long but maybe less stress full? Thanks
