Hi,
We have had our hot tub for about 2 months. I was using dichlor only until about 2 weeks ago I refilled and switched to using dichlor/bleach. The bleach I am using is 14% liquid chlorine. I used dichlor for a few days until I had added 22ppm CYA. My problem is if I take the FC level up to 12ppm at in the evening, by the following morning it has dropped down to around 5ppm and that is without using the hot tub. I didnt seem to have this problem with dichlor.
My thoughts are
a) this is normal - so I just live with it
b) I need to raise my CYA level
c) There is something in the water using up the chlorine so I just need to continue taking it above 10 ppm each night and eventually the usage will reduce (or I will run out of chlorine)
My other reading are
Ph : 7.4
TA : 60
CH: 200
Any help would be apprecicated
Thanks
