Good stuff for my jacuzzi

As described

It is 100% sodium bicarbonate, AKA baking soda. So it is quite overpriced, but I suppose having it in a plastic container is nice versus the cardboard box you can buy for a dollar.

’ve been using this with my Coleman SaluSpa, and it’s done exactly what I needed it to do. My alkalinity was a little off, and this brought it back into range pretty quickly without a lot of guesswork.It dissolves well and doesn’t leave any residue, which is always a plus when you’re dealing with spa chemicals. Once balanced, I noticed the pH stayed more stable instead of bouncing around, so I’m not constantly having to adjust things.The container size is also practical—you don’t need a ton each time, so it should last a while depending on how often you’re maintaining your water.For the price, it’s a great value and an easy addition to regular spa maintenance. If you’re running a SaluSpa or similar setup and need something reliable to keep your water balanced, this does the job well.

Good price and works well

I had been struggling with fluctuating pH levels and cloudy water, but this product made it so easy to get the alkalinity back to the optimal range. It dissolves quickly in the water and doesn’t leave any residue or cloudiness behind. I noticed a significant improvement in water clarity and feel almost immediately after using it. It also helps stabilize the pH, which means fewer adjustments are needed over time. The instructions are clear and simple to follow, and it’s easy to measure out the right amount for my hot tub’s size. I’ve used this product a few times now, and each time, it does exactly what it’s supposed to – it restores balance to the water and makes my hot tub experience even more relaxing. If you’re looking to keep your spa’s water perfect, I highly recommend this alkalinity increaser!
