ClearwaterTA Plus Alkalinity Increaser for Swimming Pool and Spa Treatment, White, 19.0 cm*9.7 cm*9.7 cm

I found our spa water was struggling for alkalinity so was good to find this product. Simply added it in small amounts over a few days until the reading was good, after that things were a lot more stable. It maybe because I live in a hard water area that it wasn't great to start with. The amount supplied in this tub is quite a lot, and should last a number of water refills or top ups to keep things level. So it's good value.

The Clearwater CH0030 TA Plus Alkalinity Increaser is a fantastic product for maintaining the perfect balance in your swimming pool or spa. It’s easy to use and highly effective at raising alkalinity levels, which is essential for keeping water clear and preventing pH fluctuations.I noticed an immediate improvement after using this product—no more cloudy water or erratic pH levels. The instructions are clear and straightforward, and the packaging is compact yet contains enough product for multiple treatments.This has become a staple in my pool maintenance routine, and I appreciate the reliable quality that Clearwater products consistently deliver. Highly recommended for anyone looking to keep their pool or spa water in excellent condition!

Good quality

Arrived on time, after 2 treatment it got the water treated spot on.

Great pool and spa maintenance chemicals. Probably others out there that works just as well but I like the easy to follow instructions and the results that I've had from it so I'll stick with what I know. Would say that the price does seem a little high for what you get but the size suits me for storage and need

Good

Brilliant ph balance stable in no time

Quick delivery and product is fast dissolving.
