I was looking on Algae Barn and debating on getting some pods to give my tank a little boost. I know I have pods because I find a couple in the filter sock all the time but I want to add more. Its a 150 gallon with a lot of rock and a lot of coral. Is 16 oz (3000 plus pods) good or should I go with the half gallon (12,000). I am thinking the 12000 might be over kill.
