I have an in-ground freeform 1200 gallon hot tub with a Pebbletec finish which really looks more like a small plunge pool. Upon instal a year ago, the pool builder included a Genesis Bromine Generator which, unfortunately, has not been able to produce enough bromine to keep the tub sanitized. We believe the generator does not work properly as it is designed for much smaller hot tubs that are covered, whereas my tub is in the open air and of larger capacity than conventional spas. As a result, I also have a floater with bromide tablets as well. I follow the BBB method and add Clorox every other day, and shock with Clorox once a week. I also have 1 inch bromine tablets in a floater.
My question is regarding the amount of bromide salt required upon drain and refill of my hot tub. The instructions from the Genesis Bromine Generator manufacturer states 1 lb. of Tru Blu (which I presume is bromide salt) per 100 gallons of water. This would therefore equal 12 lbs. of Tru Blu for my hot tub. However, the instructions on the side of the bucket in which the bromine 1 inch tablets are contained states 1/2 ounce of bromide salt per 100 gallons at start up or refill. Obviously there is a huge difference between 1 pound and half an ounce!
I am due to empty and refill my hot tub and will need to reinstate a bromide salt content for bromine reserve. Can someone please tell me whether the Tru Blu (1 lb) or the bromine tablet (1/2 oz) per 100 gallons is correct? The Tru Blu product is very expensive and I don't want to purchase more than I need. Or should I just forget the Genesis altogether and simply go with 1/2 oz per 100 gallons which would be 12 ounces total at refill, and then Clorox and 1 inch tablets forever more?
Thanks so much for this fantastic forum.
