For coral propagation, Coral Accel should be used daily. It is a clean product, however, water quality should always be monitored. You must judge overfeeding by the condition of your aquarium. Kent Phytoplex marine phytoplankton is a good choice to feed daily along with the Coral Accel. Feed Micro Vert once weekly in lieu of Coral Accel. Continue your normal regimen of Kent Kalkwasser, Tech CB and Coral-Vite. Kent Marine Essential Elements should be used simultaneously to replace those minerals lost to protein skimming and carbon or resin filtration. Tech I Iodine will provide excellent results. Live corals require strong lighting, with proper spectrum and strong water movement, in a well seasoned aquarium. Do not attempt to propagate corals in an aquarium that is less than a year old. Regular water changes with Kent Sea Salt are encouraged. Use Kent Marine Superbuffer-DKH or new Pro Buffer DKH to control alkalinity, prevent pH swings, and encourage deposition of new coral structure.
