SeaKlearPhosKlear 4000 Natural Clarifier, 1 gallon

expensive, but it works. I had struggle to fight algae, shocking the pool this year did not seem to yield the usual results, and i tried different brands of shock to no avail, and i used water clarifyers, and algae killer, but things were not working. i learned then that it may be a phosphate problem, so i used this product and so much improvement with the first bottle. ordered a second bottle and used half. pool is now clear. be ready to clean filters though.

Best product I ever used

Works as described..will buy again!!

This product is great. I had a algae in my pool. The water was clean but I had algae along the walls. After using this and brushing the wallsone more time the pool has remained algae free. Of course the other chemicals must be correct also

was not aware use of this product over time would cloud the water in a pool.

Worked very well. Highly recommend if you have high phosphates.

Great product. The phosphate levels in my built-in pool had been rising all summer. My local pool store sold me different products (3 times) that didn't work. After my phosphate levels climbed to over 2,500 PPB I finally decided to research the problem and handle it myself. I purchased this product, added 50 ounces to my 25000 gallon pool and within 48 hours my phosphate levels were undetectable.
