SpaChoice 50-Pounds Premium Alkalinity Up for Pools, Alkalinity Increaser for Swimming Pools, 100% Sodium Bicarbonate

Great value the money.

I do like the competitive price. I use this product to treat the water in our exercising swim spa.

I purchased these chemicals to replace the ones that came with the spa. These are very comparable but more affordable. I would purchase again.

Fair price for a good product. If you have a spa you know you must keep the chemicals up to par or feel the consequences. This product works as it should. No complaints about it!

What can I say? It does what it’s supposed to! Is there anything else you can ask from a product.

Works very well. Reasonable price.

Excellent product and works perfectly in my hottub. A+++

Good deal & prompt shipment
