1.I'm trying to get the max total system volume I can with a 55g display tank. What I was thinking was using a 55g display over a 55g sump. This would give me lots of room in the sump for skimmers, calcium and phos reactors, fuge, ATO, etc. It also makes the system less sensitive to evaporative water loss issues, like elevated salinity, to ammonia spike from dead fish and make the system more buffered against catastrophic equipment failures. Evaporative cooling will be the the only cooling I will do if I can get away with it. Chillers are pretty expensive and it's just hard to beat 8,000BTU's per gallon for the price of a computer fan...However when I use this design and modeled it up in SW to fit the 55g under the tank I realized that I don't have any room for components that will hang off the tank and other things like electrical connections etc. Basically when I do this the only room I have is INSIDE the sump. Should I just go with a smaller sump or should I make the stand bigger/taller to accommodate the 55g sump and room for all the extras when they get added to the system?
here is a pic of the size of everything...

2.With regard to leveling and squaring of the joints and the stand I have heard that there is a higher grade of pine lumber called white pine that is usually exceptionally straight and less “twisty.â€Â Much more so that your standard grade 2x stock. Is this true?
3.I've also noticed quite a few people who are having trouble getting good square joints at the top corners. I'm wondering if those of you who are having difficulty with this are using a regular corded or cordless circular saw? I think the best way to get perfectly square cuts and equal lengths on the load bearing legs is to use a chop, or compound miter, saw. Possibly even a table saw if you had a rip fence and a miter gage slot. For those of you who used either the compound miter or table saw, did you have any trouble getting square cuts and equal lengths? Likewise I would think that a good framing or drywall square (the large kind, not a 6â€Â x6â€Â speed square) would greatly aid in the assembly of the legs to the top and bottom and keeping all the joints square.
4.Even if you don't get everything perfectly even on the bearing surface where the tank meets the stand, I have read that the best thing to do to ensure even load distribution over a “not so perfectlyâ€Â flat surface is to use the foam insulation boards. If you worried about that pink foam board showing you can just raise the skin enough to cover the thickness of the board. Which brings me to my next question...what thickness foam is ideal?
