  • Effective pH Increaser at a Great Price
Item Package Quantity: 1 Size: 1.12 Pound (Pack of 1)
I’ve been using SpaGuard Balance pH Increaser for a while now, and it works great for my hot tub! It’s super effective at adjusting the pH levels, keeping the water balanced and comfortable. What I really appreciate is the great price for the 18 oz bottle – it lasts a while and does exactly what it’s supposed to. This product is a must-have for anyone with a hot tub, and I’ve had no issues with it. Highly recommend if you’re looking for an affordable and reliable pH increaser! ... show more
