    Anti Foam

    HTH Anti-foam is specially formulated to work with all hot tubs and spas including use in any Wood Hot Tub. Anti-foam is used to remove unwanted bubbles in spa and hot tub water. HTH Anti-foam is compatible with all sanitizers including bromine.

    Phosphates left over from washing bathing suites, can produce excessive bubbles in hot tub water. Antifoam chemical is a completely safe way to eliminate these unwanted bubbles. Simply add a small amount on to the bubbles and they will quickly disappear. These bubbles can be the source of hot tub ring (line that forms on the top surface of tub just above water line). Use Anti Foam regularly to avoid scum formed by bubbles.

    Choc sans chlore

    Choc sans chlore aka Non-chlorine shock (replaces Oxy-Pur)

    Non-chlorine shock or "Monopersulfate" (also marketed as "Active Oxygen") is a powerful oxidizing agent. It kills bacteria and eliminates residues left behind by bathers: sweat, sunscreen and so on.

    Some people rely on Active Oxygen as an alternative to bromine or a mineral ionizing system. We don't recommend this; it's good stuff, but its anti-bacterial effect doesn't last very long. It is much better to use it as an occasional shock treatment in combination wih an ozonator and brominating tablets or as a combination with an ozonator and an mineral ionizing system.

    Shock treatments are essential for maintaining clean water in your spa. You should shock the water once a week or whenever the bromine level drops to zero. For heavily-used spas (including any commercially-operated spa), add shock at the end of each day.

  • pH Booster
    pH Booster

    pH Booster

    Northern Lights pH Booster is specially formulated to work with all hot tubs and spas including use in any Wood Hot Tub. pH Booster is used to raise the pH in spa and hot tub water. Northern Lights pH Increaser is compatible with all sanitizers including bromine, chlorine and biguanide.

    Proper pH balance is an essential part of spa/hot tub maintenance. The recommended range is 7.2 to 7.6. If the pH level becomes to low, the water will be acidic. Discomfort to the skin and eye irritation can develop. Low pH levels also cause sanitizers such as bromine and chlorine to become unstable and less effective. Test water levels regularly to ensure proper pH level.

    • Effectively raises the pH level in spa and hot tub water
    • Prevents corrosion and equipment damage from low pH
    • Reliable, safe and effective

  • pH Stabilizer
    pH Stabilizer

    pH Stabilizer aka Alkanal (replaces Alka Rise)

    Low Total Alkalinity (also known as TAC) 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 of your spa water and (surprise!) to stabilise its pH.

    If you have soft tap water, we recommend that you add 100-200g of pH Stabiliser each time you refill your spa.

    pH Stabiliser contains sodium bicarbonate, which also makes the spa 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.
