Never used before but it deffinately made a difference adding the TA Alkaline to the main water made a lot of difference from the start would recommend

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!

I had run out of my genuine ones. I’ve got one from Temu but far too many things in it and said my water was off for my hot tub. Got these as good reviews and great value for money. Soon got my water back to staff levels. That test strips and a must for any hot tub starter kit

Used for our hot tub. Not had any issues. Good product

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.

Exactly what was required

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

I had really low TA so I bought this and had to use half a tub to bring the TA from 10 to about 90 (1200 litre hot tub). I tried to figure out how long I need to wait etc. to be able to use it so I googled the safety sheet. As it turns out (bit of a facepalm because it makes sense) it literally is just Sodium Bicarbonate. For the price of this 1KG tub you are actually getting between 5-10KG of bulk Sodium Bicarbonate. So yes it works. But it makes now sense why the ingredients aren’t printed on the tub.

Fonctionne très bien

Wenn Chemie sein MUSS

Fait parfaitement le job

Nutze die Streifen zum überprüfen der Wasserqualität von unserem Whirlpool und man sich sehr gut danach richten und es gut erkennen und ablesen. Ich Chlore dann nach bedarf und mache etwas TA Plus rein nach bedarf und habe seid dem eine super Wasserqualität und das Wasser ist klar und stinkt nicht.

Wie erwartet!
