Hey, if future employment brings us closer... save me a spot in your club. I'll bet you're gonna lead up to one heck of a gathering! BTW, I have 3 clams(as you've seen) and believe that depending on the size of the clams in relation to the system, that it may be beneficial to run a wet/dry for nitrate production as well as a "less advanced" filtration system. Possibly just a fuge.
