Description

Clorox Pool&Spa Crazy Water Clarifier is a concentrated pool water clarifier that creates crystal clear pool water. The formula combines the small particles that make your water dull, hazy, or cloudy into larger particles that are easier for your filter to remove. You only need 1 ounce of product for 5, 000 gallons of water to see results. No dilution needed - simply apply slowly around the edges of your pool's deep end, and allow the pump to run for at least 8 hours.

    • Good product. Would buy again and will next summer
Worked as it should. Cleared the pool up real nice but it took a couple of days and it was combined with Drop out because the pool was so cloudy. Put it in. Run the pump on high for about 3 hours and then just shut the pump off and let it sit 2 or 3 days while it works. Don’t be impatient. Vacuum pool to waste as the sediment will pass through a filter. I bought a liquid transfer pump to do this but you can remove the filter if a cartridge, plug all return lines to pool with the exception of the one to expel the cloudy water. If pump is 2 speed, vacuum on low very slowly so not to raise sediment. ... show more

    • Useful Pool Chemical

Review Image by Paul Paul
For almost two years of owning this home my pool water has always looked great. Nice and clean and clear. Then one day the water changed to the appearance of skim milk. It was probably my fault by not waiting the prescribed interval between adding the treatment chemicals. LOTS of effort was expended to restoring the water clarity. The pump has been run 24/7 for almost two weeks. A new OEM Hayward filter was installed. The filter was cleaned twice per day. AND this Clorox Crazy Clarifier was used. Being an American, of course my thought was if a little is good, then a lot is better AND I wanted the water clean NOW, so I initially used lots of this chemical. After this method didn't work for days I called the manufacturer. I was informed lots is not better. The chemical method I switched to then had great and "rapid" results. The pump remained running 24/7 w/ the filter being cleaned twice per day. BUT now, after each cleaning of the filter, I added the small amount of chemical listed on the product label. The water is almost back to normal clarity and is expected to be fully restored shortly. This chemical is recommended. ... show more

    • Definitely Purchase This as Bulk for Hot Tub Maintenance
My hot tub instructions are to put 2 oz of clarifier every week as part of weekly maintenance. Buying the smaller boutique bottles was getting really expensive. This was a no brainer in getting costs under control. I've done the same for the other chemicals I use on a regular basis (oxidizer and descaler). It seems to work fine. (FYI - When the water gets cloudy, my retailer told me to use oxidizer, which Clorox also sells.) ... show more
