180 plywood/glass tank

[dirk50merc]

Allright I have researched it read some great articles and think I'm ready to do it, a fully planted 180g diy tank 18" x 24" x 96". I am planning on using fiber glass body tape and filler in all corners and edge to edge contact. I am considering 1/4 saftey glass for 18" tall or 3/8" saftey for 24" tall.

What are experiences with tanks 24" tall or should I consider 24" wide 18" tall?

Is saftey glass a better material for this than plate glass?

I have reda that stands need to have solid bottoms can you use insulation board or styrofoam between tank and stand?

How far appart should cross members of stand be (support beam under the solid surface of stand)?

Any other thought or experiences that can be shared is appriciated

Thanks for any help or advice, Dirk

Mine is a 100g, 48X24X18 high. I used Epoxy paint about 5 coats. The tank is supported on a 2X4 frame on concrete blocks. I have a centre braise on the frame. I used solid styrofoam in between the tank and frame. No solid support. It's been up for about 18 months and holding firm.
I used 1/4 plate glass. The glass sits inside the opening I made on one of the sides. I used silicone on the inside only and did not realise wood tends to flex a little under pressure and because of this a tiny leak developed. I drained the tank and sealed the outside as well and fixed the leak.
Good luck with your project.

I built a 180 2 years ago. I used 1/2" tempered glass just to play it safe. worked great. My stand that i built was made out of 2x4s with 2 center suports to spread the weight. i put 1/4' sill seal to albsorb the pressure points between the tank and the stand. i made it the standard size. I believe it is 6'x2'x25". I know the 6'x2' is wright but i am guessing on the heigth. I modeled it off of an all-glass tank. Sence then i bought a all-glass tank just for the overflowes. wish i would have been thinking when i had the botom made for the homade tank. It is so nice not seeing any of the filters or heater.

Yup think i'm goimg to do it overall tank cost $250 vs $587 for a store bought.

*Moon- thanks, do you think two thick beads of silicone .5"+ with an outer bead (glass to edge of wood) would do the trick? I think I will do 18" tall 24" wide 96" long to keep cost in check

I plan on making my light out of 2 flourex 65 w compact flourecents has anyone used these lights? they have great luminens per watt ratio burn way cooler than HIDs and would be easy to house in a small hood w/o a fan

Can anyone email some pictures of their DIY tanks?

Thanks for all the help, Dirk

My silicone beads are about an inch thick. Half inch on each side. On the out side it is only about half inch. This will ensure that any flexing of the wood is taken care of.

WOW that's alot of screws! Started today, this project has taken on alife of it's own: 96" long (actually 84" interior with a foot cabinet on end for my canister, hoses, and cords) x24" x24". this is going to be one big bad aquarium. Actual gallons are going to be 210 gallons.

Ill keep everyone updated,

Did you use stainless steel screws and waterproof wood glue?

[dirk50merc]

used heavy duty water proof liquid nails, exterior grade wood screws (rust proof) and today I am using fiber glass ribon and body filler/sealler to seal all corners and edges with, maybe overkill but thats the way I typically do things. If you want I can email some pictures of my progress

Thanks for your advice, Dirk

[Moon]

How about posting some pics here of your work in progress?

[dirk50merc]

Moon, I'm guessing I'm more technically challanged than I thought. I have tried a couple of times to post with out any success. I wasn't shure if jr. members can post pictures? If so I could really use some help.

Thanks, Dirk

[Moon]

I am the same. I am photographically challenged. So I don't even try.

Moon I got it finally, here is where the project is at know [IMG]

[dirk50merc]

Still need to finish the exterior and add glass [IMG]

Nice work Dirk. Just need a nice finish on the outside.
A few questions
What type of paint did you use on the inside?
Did you silicone the joints?
What type of filtration? If it is wet/dry you might need to drill holes.
