Weird stuff this resin malarkey! Tulsion was brilliant when it first came out then went right down the pan a year or two back - I've stuck with it and it varies in quality. I wonder how many companies actually make the stuff? Tulsion comes from India I believe but their quality control seems to be pants.
Hi Dave,
I shared a bag of Tulsion resin with other cleaner about 3 years ago.
I used the remaining bit I had left over from that batch in my DI a year ago. My di vessel is 6 liters. I will report that its jolly good stuff, but the other cleaner said it was rubbish - same bag.
He got that bag from Pure Freedom.
I just bought a replacement bag from Daqua as it will be time to change the resin shortly. I asked him if he would like to share this bag and his response was an emphatic no.

So what's the difference? Same water, same resin but different r/o's. His is a Merlin and mine is a 4040. And we use more water a day than he does. But he is adamant that the resin is at fault.
