Review: Works as described - Works as described. Cleared the algae in my water lilies/goldfish pond, which sits in direct sunlight.
Review: Crystal Clear Koi Pond Again! - Went into August with crystal clear water in my koi pond... Until algae decided to take over. The water turned green and I couldn't see any of my fish. I came across this product and gave it a shot. Took two doses, and my pond is almost back to crystal clear again. The directions are easy to follow. This product works! And the 21 fish I have in my pond are all doing fine. Highly recommend if you need to clear up your pond. Just make sure you read the directions! You need to keep the pond aerated while using it. I have 2 aerators and a waterfall.

## 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.

### ⭐⭐⭐⭐⭐ Crystal Clear Koi Pond Again!
*by C***. on September 22, 2025*

### ⭐⭐⭐⭐ Great stuff; works well with no adverse effects
*by T***M on July 18, 2025*

Works better than any other product I've tried to control various forms of algae in a 3000 gallon pond. Water gets and stays clearer than I've seen it previously when using other algae control products. I don't have any fish to be concerned about but it hasn't harmed any of the water lilies or other pond plants. Only downside is for me it can be a bit expensive if I use as much as the directions say every week, so I'll often stretch out the applications to a lesser frequent schedule and I've found a frequency that works well for my situation.
