Rx Clear Swimming Pool pH Plus Increaser, Sodium Carbonate, Granular, 2 lbs

The RX Clear PH Plus Increaser arrived right away and worked very effectively. I am pleased with the results.

PH plus size is great quality for quantity! Works great and was less expensive here than other places. Fast shipping and came packaged nicely in cardboard box with winterizing chemicals ordered as well. Pleased with order.

Excellent product.Have need in the past.

Very knowledgeable and helpful person in customer service.

Great product easy to use.

Product works as it should and is reasonably priced.

I use these in my spa and have never had a problem, the water is clear with no strong chlorine smell

Each pool is different. To keep ph at certain level is not easy because of many factors. To compare this product with all the other products is not possible. The basic chemical in all products is the same, thus cost and handling of product in actual usage determine preference. Likely to continue using thisproduct.

PH + is working as it should.

I have ordered many times from this company and the service, and products has always been good. For some reason this year do not know if I have gotten some very old stock but have received three orders of chemicals shock, tablets and ph increase mainly that just did not perform at all. Have already used more chemical in last 3 months than I would normally use in a whole year. I am not mad and will use this company again sometime but I know this is correct because I just bought shock and ph increase somewhere else and performed correctly.
