Welcome to our forum.
... For regular use by our family, I dose 3-5 ppm after use -- and every second day if it is not used. That results in a very low chlorine reading before we get in. When entertaining guests, I make sure there is 1-3 ppm residual before use, and add enough chlorine to get it up to at least 5 ppm after. 8-)
Go to Doc's site (www.rhtubs.com) and look in the FAQ section to find the Vermonter's water treatment program. That is the way to use dichlor. Contrary to Steve's comment, the free chlorine residual can be and often is low or even zero when you get in the tub. In fact getting into chlorine free (or close to it) water is a big part of why the Vermonter's method is the best option for many people.Regards,Bill
Mmmmmm, guess I need another 12 years before I get it right? :-/[size=18]It is unsafe to get into hot water with no sanitizer.[/size] Does anyone disagree? Ask yourself what sanitizer is for... to keep the spa water safe for bathers by killing bacteria or to keep it looking clear after use?Remember people...this is the internet and not everything you read is true. Take all of this with a grain of salt and talk to professionals face to face that you can trust.
