Additional Details

ClearWater TA Plus is used to raise Total Alkalinity levels if they drop below 80ppm. Total Alkalinity is a buffer that helps the water to resist pH changes.

Well-balanced Total Alkalinity of 80-100ppm results in stable pH and more efficient sanitiser.

Incorrect Total Alkalinity can result in fluctuating pH levels, less effective chlorine, the water may cause irritation to user and it may cause damage to your pool or hot tub.


As with all chemical products, instructions and warnings should be followed very carefully.

TA Alkalinity Increaser

Was really frustrating trying to bring the alkalinity up setting up my new Toronto. I couldn't balance the ph. This solved the problem. Worth buying when your setting up your hot tub.

Product serves purpose. Customer service is atrocious. Ridiculous policies and process for getting a warranty claim complete which they don�t want to honour despite providing proof. They then reply to your review asking you to contact them. I have done and you get an email fobbing you off. Beware customer is service is rubbish once the product goes faulty.

After complaining the product wasn't delivered to our house, we were promised a replacement. No sign of it after a few weeks. No indication it has ever been sent. Can't comment on the actual product

It was so easy to use the web site and get my TA alkalinity as I don't seem to be able to buy it at my normal stores.
