Clearwater TA Plus Alkalinity Increaser for Swimming Pool and Spa Treatment, White & CH0005 PH Plus Increaser for Swimming Pool and Spa Treatment

Does exactly what is claims, so good value.

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.

Excellent product. Does what it says and fast delivery. Highly recommend!!!!

Perfect for sorting my hot tub levels out

I order this because my alkaline was low I also ordered alkaline plus lucky I had strips from my starter kid as I added the alkaline but it didn’t go up every think else seems fine so I tried the starter kit strips and they showed the alkaline was spot on ! Very worried as the other two was fine but this was well off

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.

Product was as described.

Some exactly what it should for our pool and hot tub- raised the TA
