Hi folks - it's getting close to opening up time again - looking forward to that!
Quick question - is it okay to test CYA before opening - before starting up the pump actually. I am thinking I may need to dump half the pool and would like to be able to do that and refill before starting the pump and working on other chemical levels. Planning to go BBB all the way this year.
If it is not alright, I would need to fill up and run the pump for a bit and then test and maybe dump out the new water.
