had a very busy day planned today. i went to use my new bag of tulsion resin from daqua i'd bought recently but i was showing 300ppm with fresh resin. After 1 hour of sratching my head and snapping the filter on one of my DI vessels through being impatient, I rang Daqua and I managed to order the Bio Diesel Resin. So thats £70 and and afternoons work wasted!
so learn from me, there are more than one type of resin!
