    Easy to use, just pour 30ml a week into your tub and it’ll keep the water clean.
    It is slightly on the pricey side but the quality is good as it works.

    I always order the Clearwater chemicals, they have been great quality and work well in my hot tub.
    Even when the hot tub engineer came out to service my tub he said to be careful with online sellers however when he looked at the product he said it was good. He opened it and looked at the actual product before commenting.

    Also, one of my kids have sensitive skin and it’s never been a problem in the tub.

    Product always arrives fast and well packaged.

    This product looked like the original but on close examination just looked a little faded. When opened the strips were much narrower than normal and when dipped into the hot tub the colours did not resemble the match colours on the outside in any way. This product was completely unusable.

    Does what it says on tin. Not a bad price.

    This is a very good alkalinity increaser, with a wide lid that you can actually get your measure in, rather than pouring it out and risking spillage like some other brands. Very pleased and will be ordering again.

    Golden Review Award: 4 From Our UsersBought this for the first time this season and I’m delighted. Was having difficulty with maintaining alkalinity and this has helped so much. we don’t have any problem as it keeps the hot tub within the range we need.

    Easy to use – helped me get my TA levels in line which resulted in easier PH levels which in turn resulted in easier chlorine management. Absolutely worked a treat.
    Seemed expensive but get a big tub and only need a little at a time so good value.

    Golden Review Award: 2 From Our UsersGreat item, just what I needed to get my hot tub right as this isnt in a starter kit. After days of trying to put my hot tub water right this sorted it. Tub alot larger than I expected so even better, so all good

    Great price for a product that is more expensive everywhere else.

    One word of advise though don’t open the lid and sniff the contents as the smell will not leave you for a long time and send your head west for a small time!

    Golden Review Award: 3 From Our UsersHonestly i have no real idea what total alkalinity is. It seems its important for the pool to maintain PH and chlorine stability. There you go.

    On the basis that it is needed, and it seems from the dip sticks it is as my tap water is usually very low on TA score, this is a good quite large pack of easy to dispense material to raise the values.

    It does indeed do this and therefore seems good value and effective – so recommended.

    Golden Review Award: 2 From Our UsersBrought my PH in line perfectly after just one dose as for a year struggled with PH and chlorine levels and PH plus didn’t work but just needed a little more alkalinity and now everything is staying perfect with PH and chlorine would recommend to anyone else having this issue and don’t waste adding PH plus only

    Golden Review Award: 2 From Our UsersSurprised to open it and only find it half full….. but the weight was correct, just a very big bottle.
    Does the job, doesn’t need much but is a pain to do the initial dose as it has to be pre-dissolved and unless you have very large buckets it takes a lot of jugs to get the alkalinity right For the first time. However once this is done, it’s quite easy to keep on top of.

    Golden Review Award: 4 From Our UsersBe careful and read instructions as this has to be mixed with water before being put in hot tub etc ” don’t pour water on it, but add to a measure of water and take precautions ie eyeware protection!) received promptly in good condition, At present whilst waiting for delivery, I managed a chlorine HP+ balance so that all 3 levels are well balanced after not using the hot tub for a few months. I will use this as friends recommended product when they had to resolve issues
