Hello,
we've had our new caldera salina spa for about 3 weeks now, with the in line spa frog bromine system. We cannot keep a good level of bromine in the water, no matter what we do! the highest we've seen it was at 2ppm and that was after shocking with an oxidizing shock treatment. Stayed up for a day and went back down to zero... Non chlorine shock doesn't seem to help at all, but we use it after every use. I don't use the chlorine shock as often, as I heard it is harsher on the tub and shouldn't be used on a regular basis.
Would you say it's a biofilm problem from the wet testing done at the manufacture? We're planning on flushing and draining if it doesn't get better...I contacted Caldera who told me it was unlikely, but that we could super-chlorine the spa...haven't looked into that yet
Also, i find it very hard to get good results from the test strips. we got the AquaCheck digital thing, but the results are always very different than the ones at Leslie's pool supplies...I tend to trust them more than the machine. Should I?
Thanks!!
