    • Polyp Lab One (250mL, 500mL)

      Polyp Lab One (250mL, 500mL)

      20 in stock

      What is Polyp Lab One? PolypLab One is engineered from two forms of acetate and hydroxide salts. When dosed, the calcium magnesium ions are freely available for uptake by corals, clams, and many other reef organisms. The acetate ions are metabolized by bacteria to create biologically available biocarbonate. The hydroxide salts provide further buffering capabilities.  - Does not elevate salinity. - Does not contain calcium carbonate. - Phosphate and silicate free. Ingredients: Calcium Acetate, Magnesium Acetate, Hydroxide Salts Contains Approximately: 70,000 mg/L Calcium, 16,000 mg/L Magnesium, 4,000 meq/L of Alkalinity Directions: Each Genesis Rock can support up to 350 gallons of the aquarium, our kit includes 700 gallons worth of coverage in two rocks. Heavier bio load tanks such as predator tanks for example should increase the coverage suggested above. Rinse material well with purified water, but preferably aquarium water. Our rock is specifically designed for zero leaching so we have very little dust, but we recommend washing just to be sure.  Place Genesis Rock in a plastic container, filling it with aquarium water, and then adding your favorite bacterial product. Add your bacteria to the container based on the size of the aquarium you are adding the rocks. Allow for your Genesis Rocks to stand at least 12 hours, and then place them inside your aquarium. If you are not using any bacterial supplement, you can place rock directly in the aquarium after rinsing. You can discard the soaked water to ensure no microscopic dust gets moved to your aquarium. Using more blocks than the capacity recommended above is ok, and will increase your filtration power. Aerobic - Optimized for Nitrite, Ammonia RemovalTo use the Genesis Rocks to create aerobic bacteria, place the Rocks above water level over your refugium, overflow, or suspended in your system. Run tank water over the rock, and allow the overflow to run into your water column. Do not run your entire system flow over the blocks, only around 40 gallons per hour estimated. Anaerobic - Optimized for NItrate RemovalInstall the Genesis Rocks in a very low flow area, deprived of as much oxygen as possible. This can be a low flow area in your sump or refugium, under your sand, or hidden in your aquascape. Aerobic & Anaerobic - Optimized for general performanceInstall the Genesis Rocks in a medium flow area of your tank, sump, refugium, or other portion of your system which has a medium flow of water. This will allow the outside of your Genesis Rocks to propagate Aerobic bacteria while the inner portions of your Genesis Rocks generate Anaerobic bacteria. *Be sure not to place the Genesis block in any area where it might rub against other equipment and cause damage to the block such as a vibrating protein skimmer as an example.    *Discount codes cannot be applied to this product
