H2Ocean Pro+ Clam and Filter Feeder
Will benefit all filter feeding species and will be readily accepted by clams, small polyped gorgonians, tube worms and other corals which require the smallest food types. It is especially good for increasing the number of copepods in your system or for enriching brine shrimp. 
The majority of fine particles in this product will pass through filter socks and filter floss so by using it you are feeding your tank and not collecting it in your filters.
