I'm pasting in Bill's tank stand questions from his web site so I can offer my opinions/ideas. >1 What other material is possible for framing? Is painted angle iron better, worse or >really no different? Angle iron is stronger per volume than wood, but will rust unless you can either epoxy coat it or find a place that will powder coat it for you. It can give you more space between shelves. >2 What decking material can be used instead of Plywood? That works for me. Flake board may be cheaper. (FLAKE, not particle) >3 If plywood is used, how can it be sealed to prevent splitting of layers due to humidity? If you buy exterior grade plywood or flakeboard, like is used in roofing andstuff like that. It isn't likey to separate due to humidity. But if you want some extra protection, pait it with some kind of epoxy. I'm particularly in favor of marine grade spar varnish. >4 I've planned 6" of clearance between the top of the tanks to the bottom of the 2"x4" >framing material. Plumbing and lighting will be recessed between the framing members. >So is 6" enough, too much or not enough? If you make the upper shelves shorter from front to back, and lower ones longer from front to back, it can simplify getting into the tank. >5 Has anyone mixed flourecent and incadecent lighting? In the old days of metal frame tanks, the larger tank lights came that way. >6 Can floerecent be diassembled and the components installed to allow a bulb in front >and another in the rear? Or should individual components be purchased for this purpose >instead? Some really economical flourescent shop lights come unassembled. You can toss out the stuff you don't want and use the rest. SOme lights come assembled, but can be disected and "Frankensteined" into your own living breathing light fixture. Others cannot be disassembled effectively. Shop with care. >7 What is a good combination of number of bulbs and colors for lighting above the tanks. Loaded question. You know how complicated that is because your on the Plant list. Most of the killie keepers I know keep them in the dark. >8 Will the top shelf be too warm for worm cultures (my guess is yes)? Dunno. I leave this for someone else to handle.
