Nothing I can do without another dose and I'm out of it. Shy of throwing 1lb of dichlor in there which is not enough for a 22000 gallon pool I have no more chlorine and won't be able to add more until about 6pm due to my schedule today.
A week is a long time for CYA to register.
Does it begin to have effect on chlorine retention sooner than it shows in the test?
From my experience the CYA will register in a day or two. The week I mentioned is probably overstatement but better to wait and see than to add more and get the level too high.
The chlorine tabs will give you some chlorine and some CYA but also lower pH. You can use them and keep an eye on the pH.
From the look of the pool it is moving along even faster than I thought it would which is great.
