Product details

Pool Season Alkalinity Up is a granular total alkalinity increaser in a 5 lb pouch. It is 100% sodium hydrogen carbonate, the same chemistry as sodium bicarbonate, with nothing else in the bag.

What alkalinity does for you

Total alkalinity is the buffer that decides how hard pH is to move. When it is low, pH bounces around after every addition and never settles, which is the state that causes staining, corrosion of pool surfaces and metal, and sanitizer that never quite keeps up. Raising alkalinity into range makes the rest of the water chemistry hold still long enough to manage.

Using it

The product is granular and made to be simple: broadcast it and let circulation carry it through the pool. Test after the water has turned over rather than immediately, and correct alkalinity before chasing pH, because pH will not hold while the buffer is low.

Questions and answers

What people ask about this product, answered by our pool techs.

What is in it?
100% sodium hydrogen carbonate, which is sodium bicarbonate. There is nothing else in the pouch.
Why does total alkalinity matter?
Alkalinity is the buffer that holds pH steady. When it is low, pH bounces after every chemical addition, which leads to staining, corrosion and sanitizer that underperforms.
Is this the same as pH increaser?
No. This raises total alkalinity. pH increaser is a different chemical, and low alkalinity should normally be corrected first so that pH will hold.
What size is this pouch?
5 lb. Pool Season lists this product in various sizes, so check the pouch weight if you are buying for a larger pool.
