BioGuard Polysheen Blue Clarifier, 1 Quart, Single Pack

I used this stuff back in the day and decided to try it again. FANTASTIC!!! Pool looks super blue and clear.

Helped a little but not enough to make a difference for what we needed

Good product does what manufacture says. I use it every 7-10 days with a small amount of phosphate inhibitor. Every one says I have beautiful clear pool water.

Sand filters allow micro particles like dead algae to flow through. I regularly use this a couple of ounces a week to help the sand filter pick these particles out and turn dull water into sparkling water. I've also had to use it a couple of times for algae overgrowth. Once dead, it can make the water quite murky. The trick to using this for clean-up is: 1] Overfill the pool above the skimmer 2] Pour this product into the skimmer at a rate of 1/2 bottle per 10K gallons of pool water to disburse it into the water and let this circulate for several hours. 3] Turn off the pump to allow the fine debris to settle on the bottom 4] Use the vac-to-waste setting on the valve and quickly vacuum the pool. You'll lose water, but this is sucking the debris right out of the pool and out of the system entirely.

Works well, drops dirt out with in 24 hrs and then you need to vacuum… says only 2ozs needed but that never seems to be enough.

This stuff works great when I have cloudy water. A little goes a long way.

Quality product at a good price. This is the clarifier that I use all season.

This product clears my pool water better than any other product I have used, including shocks. Highly recommend.

super bon !

Great
