(Man, Boomer pulls no punches, does he?)

Brad, not to try and pick a side here, but I saw the box of carbon in question. It clearly read on the side: "For freshwater use ONLY." Like you (and others) I too thought the notion was totally absurd that it could have been the carbon, but, (and Alan can feel free to jump in here and correct me if I am wrong) I thought the green water went away almost immediately following his decision to discontinue using that carbon.

Frankly, if it was the carbon that caused his woes, that's a brand I'll just stay away from altogether, saltwater OR freshwater or whatever. No thanks!!

I could be remembering wrong. I wasn't in town when the greenwater finally cleared.

If I think of it, I will run over to Big Al's tonight and see if I can find the box/brand of carbon that had this statement printed on it .. (Or Alan do you happen to remember what it was?)
