The most common way to kill bacteria in your pool and keep your swimming pool water healthy is to use chlorine. Before using chlorine, it is important to have a correct water balance first. Once this has been achieved, chlorine levels between 1.0-3.0 mg/l should be satisfactory to preserve bacteria free swimming pool water. There are two ways to tell if your pool is a well-managed chlorine treated swimming pool is that it will have no odour and the level of chloramines will be less than 0.5 mg/l. Here at Cascade Pools we have a wide range of swimming pool chemicals for you to choose from to suit your swimming pool requirements.

Multifunctional 200g Chlorine Tablets
These tablets are designed to slowly erode over 3-5 days depending on the water flowing over them.
Tablets contain clarifier & algaecide
Prior to using this product, adjust the pH levels to the ideal range of 7.2 – 7.6
Note: As the tablets release chlorine relatively slowly it may be necessary to shock dose or oxidise prior to their use to first establish some chlorine more rapidly.
Application Instructions: Place one tablet in the skimmer basket per 45,450 litres (10,000) gallons and adjust tablet numbers as necessary to take account of your water flow to achieve 1-3 mg/l (ppm) relatively consistently. If using a Floating Dispenser fill with tablets and adjust the aperture mechanism to obtain the desired chlorine range of 1-3mg/l (ppm). Alternatively keep the dispenser aperture constant and vary the tablets inside to achieve the ideal chlorine range. The dispenser should be removed from the pool while swimmers are bathing.
Chlorine Feeders: Few feeders take the 200g tablet so the smaller 20g tablets may be required. Fill the dispenser and follow feeder instruction manuals on flow regulation to maintain 1-3 mg/l (ppm) chlorine levels.
