Hi,
I have a new small hot tub. 130 gallons. Filled it (hard well water) and got it up to temperature. Does anyone know if the TFT test (TF-100) kits react the same to hot water as they do with cold?
My TA is around 100 and doesn't seem to want to increase to the 125 recommended in the manual.
My PH is high, 8.2, and I am concerned about trying to move it before getting TA to where it is supposed to be.
My CH is 130. They recommend 150 and I am trying to raise it.
My FC has been struggling to stay up. Only been 3 days though.
I have been told bromine is preferred for hot tubs, but I am using chlorine because a bunch of chemicals came with the hot tub and there is this silver ion thing that doesn't work with bromine.
A few questions...
Can I use the same methods to change the levels as I do with my pool? Same ideas apply? Liquid chlorine better than solid, muriatic acid, baking soda, etc.? Or should I be using spa specific chemicals? Should I be checking CYA?
Any help is welcome. First thing is to make sure I am getting accurate readings.
Thanks very much.
