Works quick and is quick dissolving

Have a pool? Then this is a must have to be in your stock. Sodium Bisulfate. Ph decreaser is awesome. Works fast to lower your ph and alkalinity. I used this last season and worked great it's quick dissolving and the QR code is a great resource if you need it. On the back it provides you with a table to assist with putting in the correct amount when needed. Made in the USA!

Works as advertised!

We are getting our pool ready for swim season and needed to add chemicals. I'm very happy with how this product worked to help start to balance the chemicals in our pool. I'd highly recommend.
