Review on Seachem Reef Zooplankton - 500 mL / 17 fl. oz. by Cassie Marie

Easy feeding of filter feeders in any aquarium. I use it in my marine and brackish water aquarium. Both my corals and other filter feeders (clams, scallops, oysters) responded very well. You really can't overdose, but you don't have to use a lot. I put the cap on all day and everything thrives.
