Low Total Alkalinity can make it difficult to maintain the pH of your hot tub water between 7.2 and 7.6. Use pH Stabiliser to increase the total alkalinity and to stabilise its pH.
HTH Alkanal is a fast-dissolving powder with no residue compatible with all filtration equipment. If you have soft tap water, we recommend that you add 100-200g of pH Stabiliser each time you refill your hot tub.
pH Stabiliser contains sodium bicarbonate, which also makes the water feel softer on your skin.
Note: HTH Spa has redesigned this reference, so you could read “Alkanal” on the presentation label rather than “pH stabiliser”. It is the same product.
