BioGuard Polysheen Blue Clarifier - 1 Quart, Fast-Acting Formula & Highly Concentrated Water Clarifier, Effective for All Swimming Pool and Filter Types

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

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.

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. I use two oz a week to keep mustard algae at bay.

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.

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

The best !

Great

super bon !
