some one posted about using two di containers and changing resin in a certain order to prolong life , any one want to remind me
by the way i have ro man 300 with one 750ml di and was wondering if a bigger di or multiple di units might extend resin life? I already have a routine where i remove only blackened resin from cartridge then take out clean used, set aside, half fill with fresh then top up with clean used i find that thismakes my bag of resin last about half as long again but its still a regular expense so if i can get more out of it then i will be happier
