Really sorry to hear things haven't improved Adam. Can't imagine loss on that scale.

HC-GFO from where?
I doubt properly working gfo knocks the levels down noticeably with one pass. I always thought it would take a small amount out (too small a change to detect) but it's the continual running of water through it that brings the overall level down in a measurable manner over time?
