does anyone have any basic stand designs for a 36"x18"Hx15"D tank i am not looking into making a cabinet sort of thing just a basic stand

Well I was going to say base cabinets can make a great stand... but you're not looking for that. Plus they can be more expensive than just buying a stand outright.

It's really going to depend upon how simple or complex you want it to be though. You could build the whole thing out of 2x4's with a couple sheets of MDF. It wouldn't look very nice though, not to mention you'd have to seal the MDF REALLY well since it's going to be in a wet environment.

Here's a basic design similar to what I was describing: http://saltaquarium.about.com/library/blank/bldiy2x4cabinetframe.htm

Here's a DIY cabinet design: http://saltaquarium.about.com/gi/dynamic/offsite.htm?zi=1/XJ&sdn=saltaquarium&zu=http%3A%2F%2Fwww.garf.org%2Fstand.html

And here's what I would call a BAD idea: http://saltaquarium.about.com/od/algaemarineplantcare/l/bldiyaqstand.htm

thanx heaps i have been looking heaps for a stand deisgn and i fouind the cabinet one but dad said he just wanted something basic and now my friend is going to take some photos of his tank stand which is quite alike to the one you mentioned so i guess if i am lucky it will be all set-up by the end of the week and i will post some pictures in my tank diary

Let me know what you find out in your search for the perfect stand, Bartier.

well so far i have found out that my perfect stand is just going to be a really really basic one :) lol i must just chuck a sheet or something over it 2 make it look nice and hide the stuff on the bottom shelf

I have two of the stands shown on the link below. The one pictured holds a 30 over a 37? gal flat back hex. The other holds a 20gal over a 30 gal terrarium. They're made with 3/4 plywood, 1x3's, and some 1x2 scraps. Everything is glued and screwed. The hazard with a lightweight stand like these is lateral movement. A partial ply back would make a big difference but I didn't like the look. However I would use it on anything larger.
