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.

Blue Horizons Multifunctional 600g Chlorine Block containing algaecide and clarifier. pH 3.0
This product is an ideal holiday treatment as the tablet is designed to erode over 12-20 days depending on the amount of water flowing over it.
Prior to using this product adjust the pH level to the ideal range of 7.2 – 7.6. Chlorine levels should be maintained between 1-3ppm.
Application Instructions: Remove the circular tab, prise open the lid and place the container and its contents in the skimmer basket. Keep the filtration running as normal. This will allow water to flow over the Multifunction block, helping to maintain a chlorine level in the pool.
As a guide use one Multifunction block for pools up to 10000 gallons or two Multifunction blocks for pools over 10000 gallons.
NOTE: The pool filtration water flow is unique to each swimming pool so dose rates may need to vary due to each pools circumstances.
