The Pond GuyOxy-Lift Defense Powder Treatment, Lift Scum, Sludge & Stains from Waterfalls, Rocks & Fountains, Reduce Water Garden Maintenance - 2 Pound

Purchased Oxy-Lift in a kit. Only put one scoop (oz) on waterfall .. left it 20 min to work .. turned pump/waterfall back on. ALL of my fish DIED within two days! Five 1-year-old Koi and several healthy Goldfish. They are not responsible if your fish DIE .. even if you follow package instructions! BEWARE!!

My father used Oxy-Lift Defense per package instructions (16 spoons for heavy debris in this situation) and all 32 of his large Koi fish were dead within 20 minutes. The product was the only possible change in their environment and he's had these fish for about 5 years without any deaths. These were his "prize fish" that he has taken care of every day, and my parents are quite upset. Beware.

This product is the best algae remover on the market for your waterfalls. Just shut off falls, sprinkle on and let it sit 20 minutes then turn the feature back on. By the next day the algae will be gone. I also use the nature's Defense and Water Clarifier by Pond Logic, but prefer Micro-Lift over Pond Logic's Much Away.
