On the Coast Spa Aruba I have a diverter plate that is meant to sit on the top filter, the slimmer basket then goes over the top of that. The installer told me I didn’t need it as I use chlorine granules and not tablets. I’m now trying a natural treatment called Aquasafe and it has a weekly tablet dose, should I put the plate in and what does it do?
also anybody used the Aquasafe 90 product? I’m getting quite a bit of scum with it.
