Does your restaurant’s menu card feature shellfish? In that case, you will need a saltwater fish tank to house lobsters, crabs and other tasty seafood. Shellfish and crustaceans thrive in saltwater. The good news is you do not need to drive out to the seaside every week to stock up on saltwater, as we have a very easy to use alternative: HOMARSEL. In amongst other things, Homarsel contains sea salt and has an unlimited shelf life as it comes in practical, resealable buckets.
