I'm thinking of building a plywood tank but the cost of materials almost makes it more beneficial to just buy one when you price 1/2inch glass and acrylic. plus all the labor involved.\

but anyway everything I find says 1/4 inch can be used for anything under 12 inches tall or shorter. could I get away with 12 inch windows or portholes in 1/4 inch thinkness?

If my cost of glass was cheaper I would be more prompted to build one.

I've built 150 and 180 gallon wood and glass aquariums. A 24"x 72" piece cut and preped is $105.00. Total tank cost $300.00 using cabinet grade Birch. Tank and stand $500.00. I live in Alaska so my costs are a little higher. The first one took a long time. It's a breeze after that.

Where are you getting your prices? I get a lot of things from Macmaster & Carr, and plastics shouldn't be very expensive at all. I was given a 500g round white plastic water tank a couple years ago to use as an aquarium. I cut rectangular windows in in the side with a "sawz all" type saw, and installed polycarbonate windows. I believe they are 1/4". The windows are approx. 12" x 24" and because silicone doesn't stick to plastic I drilled holes along the edges and bolted the windows to the tank with nylon bolts and washers. And ofcoures silicon was squeezed into all possible cracks and cranies before things were tightened down.

The 1/4 inch glass is ok up to 18 inches. A website to calculate the thickness of glass required is www.fnzas.orn/glassthickness.0.html I built a 180 gal tank with a 18 inch window and grand total it cost about 500 Can with the cabinate. I would never build another tank with a 18 inch window. It is too damn small. I have just finished a 70 gallon tank with a 27 inch window. It looks awesome. I have found that the bigger the tank the more cost effective building your own is. So if you want a big tank have at it.
