That person MUST have a welder to do something like that. Look at the ROOM in that stand!! You know I could possibly fit my sump AND my aquarium supplies in there. I gotta start calling around to see who could build me one!
I wasn't sure if you wanted room for sump and such. That's why I recommend staying away from larger size pieces of wood than necessary.
Awhile ago a friend told me that I should just go get the metal and bolt the pieces together. Thoughts on that?
No experience, no opinion. If he knows what he's talking about, then I would trust him. Add plywood and it should be solid.
Also, you think that is a 8' tank? Single center brace, oh that would be great. Where did you find those pictures?
Check out reef forums for plans: reefcentral.com, reeffrontiers.com I used to be reefer but family got in the way. My friend posted that design as an idea for his 8' 370g tank. Not sure what size is the one posted.
