From reading a few posts here I guess ionizers are generally frowned upon for use in plaster pools...
Have a 800gal wood teak hot tub with equipment about 15feet away.
chem geek mentioned not to use if not NSF approved, cant seem to find out if it is on NFS website search.
I use granular dichlor and hydrogen peroxide and try to balance once a week.
p-15 inonizer was disconnected when we got house /copper probes are in need of replacement should I order new or use spaRX(in pump basket) instead?
ps from posts here on TFP it says to have TDS, if CH is balanced around 150ppm would that be enough? adding salt is very harsh to the wood right?
