1 kg pH Plus Increaser Granules for Hot Tubs and Swimming Pools, pH Level Booster for Spa and Pool Water Balance, Improves Water Quality, Supports Chlorine Effectiveness and Comfortable Bathing

Ordered other products before and they are all used up in 5 mins this comes in a proper sturdy box with proper measures and clear instructions plenty of test strips and potions to fix all in the tub

Would recommend easy to use and instructions for the set up of the spa is easy 👌 😎

Having just set up our new inflatable hot tub I needed a chemical starter kit and they all seem to be much of a muchness so went for this one. The containers are full and have clear instructions. The different measuring spoons are useful and the test strips easy to operate and gave readings for all three parameters so for the money I'm happy.

Keeps the pool clean but I find instructions very confusing. So I googled how much to add for a 10ft pool.

Brilliant kit for hot tub lasts for ages

It arrived torn to me

Good product for a good price.

Great product , thank you
