New pool (shown in the Under Construction section). Looking for a pool service as we will be gone quite a bit over the summer. The service person and I were discussing what was needed with a SWG pool and he made a long statement how several states (California, Florida, etc) had tested SWG and shown that they increase the calcium in the water. I cannot figure the chemistry in that. Now our area has high CH source water (250) so it will increase over time in the pool with evaporation thus leading to a drain and fill every year or so. But the SWG adding calcium? Any thoughts?
He also stated that we had to monitor phosphates in this area due to bird fecal matter causing yellow algae. Said they use Sodium Bromide as the chlorine does not kill it. Another one I cannot resolve --
