Review on Optimized Pond Nite-Out II - 16-Ounce bottle by Microbe Lift by Gary Konduru

I had to restart the filter after the pond repair. I was afraid of how long it would take for the filter to work, especially since I had to have 8 koi there. I contacted the company with many questions and received the best email support which was very helpful. I used it every day and it continued to release nitrite which reduced the number of water changes (rock salt in the pond helped protect the fish from high nitrite levels). My filter lasted 4 weeks instead of the usual 6.
