Store tightly-sealed. Do not discard desiccant packet in container until contents are completely used. Do not contaminate container with foreign material. In an area of high water flow, add one level spoonful (using enclosed spoon) of ReefBlizzard per 20 US-gallons (76 L) in system per day. ReefBlizzard may be fortified with nutritional supplements by mixing the desired amount in a clean container with 1 - 2 ounces of aquarium water and adding supplements such as CoralAmino, AminOmega, Vitamarin-M, etc. Allow mixture to rest for 5 minutes, then target-feed organisms in aquarium (recommended), or turn protein skimmer off and simply add contents of container to the intake port of a circulation pump or powerhead and allow to circulate throughout system; resume protein skimming after 30 minutes. Adjust dosage as feeding requirements of organisms in system dictate. Do not overfeed. Monitor nutrient concentrations in system and take steps to control nutrients if necessary.
