Just when things were going well with my water balance, it seems I have added too much CYA. I had been working the level up from 30 but it seems that my CYA level increased until almost 10 days after the last time I added it. I do find the Taylor CA test difficult. If I do the test on a very sunny day, I can just make out the dot at 90. On a less bright day, the test seems to indicate more like 100. I am going to call it 90. Here are my full results:
FC - 6.2
TA - 90
CH - 250
CYA - 90
Borates - 50
My question is, will it do any harm to leave the CYA level where it is and just run the chlorine level a little higher? What should I aim for? ~8.0PPM?
We are almost at the end of the season in Sydney and I figure my next summer the CYA will have probably fallen into range with a few back washed over the winter? Or should I get it back into range now?
