I want to build a homemade garage setup for the winter. I have 3 tubs that add up to 450 gal and I want to double that. Cement building blocks with pond liner 12 ft long 4 ft wide and 3 ft high. Anyone with the gal size formula handy, how many gals is that?

Has anyone here done this setup or is there some threads on it here?

I concure 1080 US Gallons , one question though why build it from block why not put together a wooden frame work then build your garage pond .
More easily constructed and more easily taken down when not needed , it can also be stored

Hi Dave yes makes good sense. Have you seen any of these type built? How strong would it have to be to hold 1000 gals I wonder? One long side will rest against the wall.

Thanks, I need the space in the garage as to why I want it only 4' wide.
I think 220 imperial gallons equates to one ton of water if thats any help to you , so it would have to be fairly strong , there are a number of wooden builds of about he size you want in threads from a year ago that may be of hekp to you or perhaps the person you need to speak to would be @koiguy1969.
My own pond is free standing supported by a frame .

I guess I should report here that I did make a wood insulated garage pond 10'x4' outside measurements with 40" deep. Followed a plan posted at this forum and youtube videos. Cost about $500 including liner.

water has a pressure of 0.45 lbs/in^2/ foot of depth, so at 3 feet deep you'll have 1.34 psi or 193 LBS/Ft^2; a standard floor is usually rated at 40-50 LBS/ft^2, so you might have challenges with the sides bowing. Maybe have a 2X8 at the base perimeter, another 6 inches up, then 12 and then at 16 inch to the top of the 3 foot depth; talking to an expert like an architect or a structural engineer might be a good idea!

Liner was just able to fit as I bought an end of season cut piece for half price, could be larger, might add extra liner for next year. Gravity filter with 1500 gal/hr pump. Yes I know filtration could be better, but it's only seasonal setup.

It does slightly bow out in the center maybe 1/2 inch but I built it strong. About 700 US gal. Small fry tub 100 US gal. Garage is heated to 38-40 F so they don't eat much all winter.

Any questions on build just ask.

Thanks
Wayne

Looks great and I'm glad your fish overwintered safely :) If you want to add some easy biological filtration, I've seen ponds where they just lay boards over the pond and set up a DIY shower on the boards. over the pond.

I have added most of the outside pond media to it, filter has extra as well.

Nope none. But I did 2 winters ago in parts of walls where the insulation did not have vapor barrier cover. Without the barrier the plywood walls sweated and then frosted up under the insulation.
