Excellent product and customer service!

My calcium level was low and I followed the directions for this Doheny's product and the hardness level was in range the next day. The product was delivered quickly and I've ordered many different products from Doheny's and they all have effective and easy to use. Highly recommend this company!

Allways order a tub of this upon opening pool

Like to keep the product on hand for pool opening because my Calcium Hardness is always low at start up and this product brings it up to correct levels
