Directions: For best results adjust system KH to 8 to 10 dKH with Superbuffer dKH or Marine Aquarium pH Buffer first. Add 1/8 minimum to 2 teaspoons maximum powder per gallon of fresh water for a stock solution and let it stand for several hours. Be sure to only mix enough to last a week at a time. Note, a white precipitate may form on the bottom of the container. Above this is the clear calcareous water which should be added to the tank SLOWLY! Use drip method or dosing pump to drip into system on a continual basis to replace all water lost due to evaporation. Does not cause pH to rise significantly when added slowly, but measure pH regularly. Use Kent Marine Superbuffer dKH to control pH and carbonate hardness For best results use Kent Marine Strontium & Molybdenum Supplements also.
