Zooplanktos-S is a highly concentrated suspension of phytoplankton-enriched, adult Brachionus sp. (rotifers), their unhatched eggs, and additional crustaceans eggs, creating a rich food source for marine invertebrates and planktivorous fishes. This product contains over four-thousand prey per ml and is formulated with a proprietary amino acid to support the natural coloration of corals and other marine organisms. It is also enriched with vitamin-C to aid in recovery and is recommended to be used alongside other planktonic suspensions for a varied and balanced diet. Zooplanktos-S does not require refrigeration, but storing it in a cool, shaded area will benefit the longevity of the product. Remember to target feed for maximum effectiveness and to avoid impacting water quality. It is also recommended to rotate foods for a more diverse diet.
