I Just changed my water, going to try the Dichlor-then-bleach method. I did the bromine method but family complaining of fumes.
So I followed the start as described. 450 gallon Jacuzzi Hot Tub with ozonator.
I balanced the water, then added 1 ounce of dichlor, so that means FC should be at 10 and cya is 9? I checked the FC the next day and got a zero reading?
I am using a professional Taylor Test kit with powder and drops for the FC
So I added another 1-ounce , took reading today and now FC is at 1 PPM. all other levels ok, so I added another one ounce.
Will retest tomorrow.
So I have added a total of 3 ounces of shock ( dichlor) so my CYA should be 3x9= 27 correct?
Why is my FC not going up 10 ppm with every ounce I add ? does ozonator affect this? I am on the right track? any suggestions?
