Bob, Terry ...anyone else using it: have you noticed anything different with Doughnut? I know you all often use different coils to the ones I do, but the last lot I bought has been clogging up coils faster than it usually does.
Initially, I thought I had a poor pack of the OCC Subtank coils, but a second pack from a different supplier bought at a different time, was the same. They only last around 2 days compared to the 6 I was getting previously.
So I then tried it in a MOW tank with the V2 coils - exactly the same.
So, I'm thinking there has to be something different with the Doughnut itself.
