Product Description


This product uses the natural abilities of barley to break down sludge and string algae and combines them with the natural powers of strong beneficial bacteria and enzyme colonies. The distinct combination of natural ingredients make this an effective 3-in-1 product. In terms of filamentous string algae removal, ClarityMax is one of the safest, and most effective, economical algae treatments, and least likely to inhibit the growth of aquatic plants. It is also 100% natural and safe for fish and plants!


Please Note: For best results use in water temperatures above 50°F (10°C).
