Instant Ocean Reef Crystals 160g Bucket

Instant Ocean Reef Crystals is a sea-salt mix formulated for reef aquariums, with additional calcium and selected trace elements compared with the brand's standard marine mix. This bucket is labelled for a nominal 160 US gallons of prepared saltwater; that figure describes mixing yield, not a weight of 160 grams.

Prepare saltwater in a separate, clean container using suitable source water. Add the mix according to the package, circulate it thoroughly, and measure salinity before use. Actual yield varies with the salinity being prepared, so a scoop measurement alone is not a final salinity check.

Never add dry salt directly to an aquarium containing livestock. Match replacement water to the aquarium's temperature and salinity, and monitor calcium and alkalinity as part of routine reef care. Keep the bucket tightly closed and protect the unused salt from moisture.
