Links to DIY backgrounds

I bought a used 55 gal tank to play with a 3D background. After looking at several on youtube I decided to try the PVC idea. I got some pieces of 2, 2 1/2 and 3 inch tube and ripped them in half on a table saw. I glued them together across the back randomly and cut holes for caves. I painted the tubes black inside and out, foamed them and then drylock them with some concrete dye mixed in. I glued a few plants up and down the walls. It came out pretty descent just couldn't get the color I wanted even mixing the dyes. I was trying to match the native granite rock around here from the Witchita Mountains which I use in my tanks. I have holes near the bottom of the tubes and then put enough gravel in the tubes so it runs out a little. That way if a fish dies and gets stuck they can be gotten out of the tubes from the bottom. That hasn't happened so far. Knock, Knock. It's been running for about 3 months now with no problems. Only thing bad about it I have so many caves sometimes you can't see a fish in there. The other is the tubes take a lot of room so the tank is not very wide any more. All in all I like it and the fish seem to love all the caves.

Hi guys, I'm a new member here.
Just got back into fish keeping from a 5 year break after emigrating to Australia from the uk, I've had a little tank for a while and a few weeks ago we bought a 60 gallon for the living room and it's given me the bug again.

I wanted a large tank, I had a 6 foot tank in the UK but it was only 18 inches tall and I always wanted a bigger one, after seeing the price of the larger setups I decided to make one myself, I've finished the stand now and it's more than strong enough.

Measurments of the tank are 2,429 / 900 / 600
280 gallons or 1050 ltrs.

I know it's my first tank build and I should start smaller but I'm a carpenter by trade and I work with more than just timber.

And if I'm really honest I do love having a project, I built 1 bed, 1 dining table, 1 coffee table, 1 bench set (to go with the dining table ) and that pattern I'm sure will continue.
Plus the wife will only let me have 1 more so I'm making it a big one.

I'll try to post some pics of the project as I go, ordered the glass today too.

Wish me luck.

This is a background I made. I used 2" styrofoam board from Home Depot for the medium. It was $20 for a 4' x 8' piece. I siliconed several layers together in some places where I wanted to add a piece jutting out. I textured it using a 3/4" spade bit on my power drill running it parallel to the surface as opposed to into it. Then I put a coat of drylok over it and then about 10 more coats each tinted a different color with acrylic paint. Some advice, use more silicone than you think you need to attach it to the back glass, styrofoam is very buoyant and if it comes lose it will come out the tank like a rocket ship. Also drylok won't stick to silicone so wipe away any excess on the front before you apply the drylok.
