I used my hot tub last year but only put bromine in it, in a floater. I drained and filled it every 3-4 days while it was being used.
I left it empty for a long time, my wife was pregnant and couldn't get in it with me so it wasn't really any good for much. Now I'm ready to start using it again.
I want to maintain the proper water chemistry from now on. I filled my tub, got a water sample and took to my local pool store. They tested it and I done exactly as they said.
Now I've tested the water twice on two different days, and the strips say there's almost no bromine in it. I filled the bromine floater and set it at the 350gal setting for my tub. I turned it to 450gal yesterday and it reads the same on the strip. (0ppm-.5ppm)
The other stuff reads dead on reading with the strips. I've read some of the other threads about bromine and I think maybe I have algae or some build up in the pipes/pump because the hot tub sat for a while and the chemicals weren't maintained before. Should I put 1 fl oz of bleach in the tub and go from there?
