View Full Version : Stand for 850 Gallon Glass Tank

07/19/2017, 02:31 PM
Hello RC, I am upgrading the tank and going for Glass Reef Tank size 90" wide x 60" Deep x 34" High, I want to build the stand for this beast and I have few ideas in my mind, I can do with 3" Extruded Aluminum T-Slot or Steel Stand that will be 2" Square tube with Enough Supports, What you guys say, I know there are plenty of people on RC who own larger tanks, Please give your suggestions since this is gong to be 1 time shot. I want it to be strong and cost effective at the same time.

Thank you all,

Wow, that will be a beast. Don't really have stand suggestions, but definitely post some pictures as you get everything up and running.

My first choice for something on the "big" side is always steel

I was dealing with the same problem on a similar sized tank (120 x 36 x 30). I was also going to use aluminum extrusions. I bought and cut all the extrusions, assembled the stand, but at the end of the day, I decided to just get the stand included from the tank builder. The T-Slot nuts just did not give me confidence that they would not let go, leaving the uprights to pancake with the tank filled.

I have a welded stand now made with tubular steel and powder coated. I will need to keep an eye on it for corrosion, but I have no worries about it's strength.

My $0.02 is to use a welded steel stand.

welded steel or concrete blocks

I am leaning towards Steel Stand but Concrete blocks might be good as well, I will not be using space under the tank anyway due to height of the stand.

Pick the material and construction method you're most familiar with, if you're doing the work yourself. It's completely possible to design and build a stand out of a variety of materials, regardless of tank size.

The closest I've done to this is building a stand for a tank that was 770 gallons (in a local museum). We used conventional 2x4 construction. It's been in place for around 10 or 12 years, I'd call it a success.

Thank you der_wille, I have decided to use construction blocks on left and right side of the tank and then I will be using 3 pcs 3" x 3" square tubes from left to right, I will use epoxied marine grade 3/4" plywood that will sit on top of the steel tubes and then 1/2" Styrofoam on top of the plywood, I think 3"x 3" tube is will be fine. I will make sure that wall of the square tube is thick enough, I will have all the access under the tank to add storage or very large sump ... what you guys think of this ideal/design

If you don't need to use the stand under the tank and have a concrete floor, then we always used cinder blocks with the "foam" board on top of them to level it out a bit (forgot what it is called, but they use same stuff with steel stands. We did the blocks ever two feet, or so and on the corners. You could park a 18-wheeler on this... the concrete does not bend like wood or metal will.

We always had the sumps out the back so only pipes and cords need to be under the tank.

That is good idea as well, as of right now I have pavers were tank is going to sit but I having concrete poured in where tank is going to sit and then concrete blocks and 3" x 3" tubes.
