Regarding the cl tabs... I know. This is an experiment in process. I did call the mfg, they said it would be fine... but I am (like you) - skeptical. I would never have done it, but I have two other people in the marina doing it and have been for 15 years??
I will say one thing: that smell that seems to permeate boats is gone from mine. Within an hour my boat smelled BOAT SHOW NEW BABY!! HAHA!!
Course, I have this strange blue liquid leaking out of the head, the holding tanks, etc... but hey, it all goes in the bilge and dissapears? (I wrote that for Surf's benefit, whom I think has left the board).
