We bought a house two years ago that happens to have an indoor pool, not the reason we bought it. The pool is 20 years old and hadn’t been used for perhaps ten years. We changed the pump, cleaned the filter, added a UV lamp and got it working. Then it got complicated because everybody has opinions on outdoor pools and nobody knows about indoor pools, especially the professionals. So it’s been a voyage of discovery.
The pool is around 45000 litres is heated and has an excellent cover. It almost never gets any sunlight. My current chemistry looks like this
free chlorine 3.1
CC 4.2
pH 7.4
TA 240
calcium hardness 350
CYA 27
I never get algae and the water is clear. We live in an area of limestone so the water is naturally hard. The pH rarely moves and once I realised that stabiliser was pointless the CYA is stable too.
My question is around the CC. It is invariably above the FC and marches in lockstep with it. But we have no smell of chlorine or stinging eyes. Is this ok?
