As i have said. i was not there for the presentation. so * In nature, each gorgonian polyp eats up to 8 times a day, grabbing food that is being deliverd on currents that are up to 132,000 gallons per hour. No way we can replicate that. no. we won't match 132k per hour. increase the "food" concentration by 10k at 1300gph and it evens out. i won't even get near 8 times a day, let alone per polyp, and how that is measured. that is a question for the Dr. I would like to go on about frequency and amount but my corals are out of dog food........since mixture don't matter.
