## Questions & Answers

**Q: my Filters clog daily and have UV clarifier with this help clear filters?**
A: If its algae that is clogging your filters then algae ide works real well. Ive been using it for about 3 yrs now and never have clogged filters from algae.

**Q: I have an approximate 90' x 40' x 2-3 ft deep frog pond.  Will Algaefix harm the frogs?**
A: I have had several small local frogs throughout the years and they seem to do fine. My pond is 10 x 20 cement and I have had turtles that are not harmed by pondcare products.

**Q: Can this product be used with a a UV light?**
A: Algae fix reduces oxygen in the water and as far as I know a UV light does not do that, so it should be okay, but I would as a expert pond person such as at Aquascape.

**Q: How much is used per gallon of pond water?**
A: 8 ounces treats 2,400 gallons. To use: Add 1 teaspoonful of PondCare AlgaeFix for every 50 gallons of pond/fountain water. Repeat dose every 3 days until algae is controlled. Do not use with crustaceans, including crabs, shrimp, and freshwater lobsters.
