Pool owner here practicing TFPC method for the last two seasons. I have just recently purchased a used stand alone hot tub(firs time with a hot tub, no experience). Currently in the process of setting it up. I wish to use chlorine rather than bromine as my sanitizing method. What is your approach to administering bleach(once you reach desired CYA level with dichlor) to the tub without a mess/splash-out? Do you guys transfer the amount required from the bleach bottle into a measuring cup or do eyeball the amount and dump directly from the jug? What seems to work better? I understand this might be a stupid question but I'd like to understand how you guys do it to make it trouble free as possible. Thanks again.
