i always stick with 000 BUT i did some tests at home anything up to 014 to 017 leaves them real nice still. hope this helps

002 for me, although you may get away with it a bit higher during winter.

i used to use 012, but had a couple of complaints so now its .000 only!

  I have accidently used 30ppm before now and not had a complaint, I happily use upto about 20ppm, but the again I am good!

[DanC]

Yeah I did that, went up to about 013 without realising but didn't get any complaints.

Used much higher than 001 it will be fine

i have had 51 with no complaints. There cant be much difference at all with 1 or 20 pparts per million its so minute. Id love to know the recomended ppm to change where windows will spot. Im convinced these suppliers are full of it regarding resin  change.

well i have 35tds coming straight out of tap sometimes here.so in essence i could just use it with no treatment whatsoever then??

[roundbuilder]

id try if i were u daz. I have never  tried with mine as 380odd ppm out the tap. Maybe i will though after ro and no resin. Prob a long shot but worth a go.

I change my resin around 5ish but I am not bothered by it as long as it stays below 10

i use mine at 3-4ppm as it comes out my ro at that. You tds meter could be 1 or 2 out so using 1 is fine IMO
