PONDCARE MICROBIAL ALGAE CLEAN Biological Inhibitor of Green Water, Alternative approach to algae control, 1-Gallon Bottle

I use this product once a week in a 12,000 gal. Koi pond. It takes 5 1/2 C. Per treatment so a little pricey but any other products would be the same. So far, this has kept the water beautifully clear but we'll have to see if it continues to work in the hot Texas sun. This co. Gives free shipping but built into product cost. They are very quick in shipping and packaging is good for liquids. Never have had a spill.

too expensive

Algae infected in fish pond. Two days after using product I can actually see my fish! Happy days are here again!

It works in a way, but I have to dose it more often and a higher dose than factory suggestion, turn out expensive.Very poor customer service.

I have to drain my pond weekly this product doesn't work , even after doubling dosage I still get green sludge alge. Going back to my original .

It did the job I wanted it to do, my pond is full of algae and it cleared it somewhat, Algae is an uphill battle especially in the open hot areas of florida

works great love this stuff

I have had ponds for 15 years. This stuff works great with little effort and you clean the filters a little less often. I love it!
