UK Indoor Pool Refurbishment

[Newdude]

CYA 10 (waiting to see whether this needs to increase once the pool is in-use and uncovered as I don't know how much UV gets filtered out by the windows/glazing)

We rec CYA 30 for indoor pools and spas for bather comfort. You don't 'need' it, but you'll likely want it.

Will add a bit more tomorrow then and bring FC up slightly too. I've got a big tub of CYA already and just didn't want to overdo it when I first added some.

With a fresh fill, it's the only time you'll ever know it's truly 0. But people misjudge their volume all the time, so best to creep up to the target.
