‘BLUE HORIZONS’ – The brand you can trust. POOL FUSION 175g Sachet of Oxidiser(SHOCK) treatment. Fast reacting formula for rapid water recovery, destruction of non filterable wastes and added clarity. 1 x 175g Sachet treats up to22720 litres (5,000 gallons). Recommended for use as a weekly product for routine oxidisation (shock), but may also be used to remove excess contamination after heavy bather use or prolonged good weather or after holiday neglect. By ‘shocking’ your pool you actually increase the chlorine level. The purpose of this is to raise the chlorine level to remove bacteria or any organic matter from the water. This process should occur weekly, in peak use it should be shocked more regularly. Using tablets that release chlorine slowly does not provide your pool with sufficient amounts of chlorine to shock the water. Unlike chlorine based shock, where you cannot go into the pool until the chlorine levels have returned to a safe level, with non-chlorine based shock there is only a short wait before you can return to the pool. Cascade Pools has a wide range of Blue Horizons chlorine and non-chlorine shock products in tablet, granules and liquid form.
