Just last week while I was waiting for my new upgrades of the Seio 1500 to arrive, I was down to about 1000g/hr of circulation from 2500g/hr. In the middle of the night I noticed the polyp extension on the Acros has been longer than any other time before. It normally extends considerably at night, but on these two days, it was double or triple it's length.This leads me to believe that low current does benefit the corals feeding habbits in some way....good I hope. I may have to do futher testing to see what the long term affects are. No signs of decline or bleaching on any of the corals previously in high flow areas.
