MICROBE-LIFT Microbe Lift 16-Ounce Pond Large Fountain Cleaner 10LFC16

good product

In my front lawn I have a lion's head fountain that continually draws praise. The problem with the fountain is that like any open air water cache, moss and fungus are attracted to it. The resulting green, murky water did a disservice to the fountain.Initially, I used the natural clarifer that I use with my hot tub to maintain the clarity of the fountain's water. The clarifier sort of worked, but the clarifier functioned by coagulating the water impurities so that they were removed by the hot tub's filter. The fountain did not have a filter and the result was that the impurities clogged and killed the pump.An extensive web search suggested that Fountain Clear would help. I purchased a bottle, with guarded expectations, but it really works. I believe that you are to add an ounce for 100 gallons. My fountain is perhaps five gallons so I would add half of a cap full. The entire summer the fountain water remained crystal clear ... and I do mean CRYSTAL clear. It was amazing. The water would evaporate at a rate of 2 gals a week. One week I would simply add water, the following week I would add water and half a cap of the Fountain Clear.I highly recommend this product, however, there is a caveat. While the fountain's water remained crystal clear, algae invaded the fountain like never before. The water was clear so you could see the algae all the better. It was no big deal because when the cold weather of winter came, the algae froze and literally flaked off. However, I will search for a chemical to limit algae growth while allow Fountain Clear to maintain the water's clarity.

It’s been helpful but not great. Fountsin still gets dirty

Just started using this brand for large 3 tier fountain. Seems to work well.

Regardless the amount of product we used in our fountain, it never helped stem the algae growth.
