my hot tub is consuming 2ppm per day FC and CC is above 0.5
using lamotte commercial 7 testing kit
hot tub had been standing for a few months with residual water in the pipes after the pump broke and I emptied the tub
after refill i have been slamming. Cya is zero, the bugs ate it when fc dropped to zero when I couldn't keep up slamming.
i even hyper chlorinated to 50ppm but still the demand and high cc exists
i will change the filter again but what else can i do? Change water? It has only been a few months since i recommissioned
it is becoming tiresome now.
Our pool is behaving perfectly...
our hot tub is 980 ltrs Toronto spa from canadian hot tubs
