CombiSanTM New Updated Formula - is a bio-activator that contains all essential trace elements in special compounds easily absorbed by invertebrates, micro-organisms, and marine fish.

You can depend on CombiSan to replenish deficiencies in the composition of aquarium water resulting from protein skimming, use of activated carbon, biological processes, precipitation, and extraction from the water by marinelife. CombiSan fosters the development of pink calcareous algae and the rapid growth of reef building stony corals. It promotes tissue repair in fish, and brilliant coloration in photosynthetic corals, anemones, and Tridacna spp. clams. It's the one marine supplement that does it all. CombiSan is nitrate and phosphate free!

 For optimal results use CombiSan and Two Little Fishies Kalkwasser, the formula Wilkens developed over 20 years ago to replenish calcium and maintain alkalinity, benefiting corals, clams, and calcareous algae that build skeletons, shells, and crusts from calcium carbonate. Dosage for new formulation: For living reef aquariums with heavy use of protein skimming and activated carbon, begin with one drop per gallon, weekly. Slowly increase the dosage. You will notice improved coloring, expansion and growth of the corals and anemones.

 Maximum dosage is 3 1/2 drops per gallon, weekly. Do not overdose! If algae growth increases, reduce dosage. Also, be sure that the protein skimmer is operating properly, and maintain pH between 8.2-8.4 by dosing kalkwasser and/or C-Balance. For fish-only aquariums use just one drop per gallon, weekly. Shelf life is 3 years. Keep out of reach of children. Not for human consumption. For aquarium use only. Not for use with fish raised for human consumption.
