💦 Clear waters, zero algae—own your pond’s glow-up!
Crystal Blue Plex Lake and Pond Algae Control is a liquid copper sulfate solution designed to eliminate various algae types effectively. It remains active for up to 30 days, with one gallon treating a 1-acre pond between 1 and 3 feet deep. Safe for most fish species except Koi, Goldfish, and Trout, it requires careful application to avoid oxygen depletion, making it the go-to choice for maintaining vibrant, algae-free ponds.
