There are other things you can do to get the best out of the chemicals you use to sanitise the pool and to keep the water clear, blue and inviting. For outdoor pools, it makes sense to ensure the water is stabilised to prolong the life of the chlorine. Tests have shown that in water that has not been stabilised chlorine dosed into the pool first thing can be broken down by sunlight and lost before noon, leaving harmful organisms and algae an opportunity to breed. We offer stand-alone stabilisers which can help with this problem.
