Maybe to help this new section get off the ground i'll post about my one and only DIY effort. A 300 gal plywood system. I say system as i tried as far as possible to make as much as possible from plywood. Thats tank, hood, sumps and apart from some strong uprights the stand too. Much more, well actualy a bit more info can be found on my web site (still working on it sometimes) at My reef setup Cheers, Viking.
