Brightwell Potassion Concentrated Potassium 8.5 oz. 250 ml.

Complex system of non-pathogenic aerobic and anaerobic microbes, as well as natural enzymes, specifically formulated to establish biological filtration in new aquarium set-ups, and to enhance the rate of nitrification, denitrification, and organic waste degradation in marine and freshwater aquaria through complete nutrient remineralization. Benefits are: 1. Rapid reduction of organic carbon, ammonia, nitrite, nitrate, and phosphate. 2. Digestion of uneaten/undigested food, excreta, detritus, and other latent organic material, resulting in cleaner and healthier aquarium substrate (without having to physically clean or disturb the substrate bed). 3. Reduction of organic compounds into nutrients that encourage the growth of photosynthetic organisms (e.g. zooxanthellae, macroalgae, plants). 4. Greatly-reduced hydrogen sulfide production. 5. Increase in dissolved oxygen concentration. 6. Limits availability of pre-existing phosphate to undesirable forms of algae and cyanobacteria. 7. Increased water clarity. Supplied in a state of suspended animation for maximum longevity. Formulated utilizing extensive data compiled by microbiologists. Liquid Royal Item Number: ABAPTS250
