Clears Organic Build-Ups
Step 2 – Algae & Nutrient Control™
Plant Essential® Freshwater Essential® Black Guard™ is scientifically formulated to clear your plants, driftwood and other decorations of organic build-ups. Organic build-up is one of the most common issues for freshwater aquariums and if left unkept, it can cover glass, wood and plants which may cause issues in your aquarium. It is important to maintain stable nutrient levels as a preventative measure, such as those found in our Plant Essential® Bio-Nutrients™, Plant Essential® Bio-Molecules™ & Plant Essential® Bio-Trace™ supplements. Please follow our dosing method correctly and do not overdose.
