aquarium rock wall

Matt would know about this, He just made one if I recall correctly. He will probably post when he sees this thread /DesktopModules/ActiveForums/themes/_default//emoticons/smile.gif

 

[hr]I just finished building one myself. Havent got my build thread started yet but I can try and walk you through what I did. I used the following: Egg crate, black pond foam, z-poxy, zip ties, and sand/rock from marco rocks. Basically I cut the egg crate to the shape of the tank wall. Then I zip tied the rock to the egg crate. Filled in all the gaps between the rocks with the black pond foam. After the foam had dried I removed the zip ties,  covered the foam with z-poxy 2 part epoxy and sprinkled the sand on to it. I will have more details/pics in my build thread I plan on starting but if you want to PM me I can give you more details or answer questions.

I built one a few years ago. Here is my thread.

But what MillerTime said is basicly what I did. I used Great Stuff foam but should of used the black pond foam.
Have any questions just shoot me a pm.

 

I think the toxic part may be true for some of the foams but you will be safe with pond foam. I have seen many tanks where they didnt even cover the foam and just let coralline grow over it.

 

here is a link to the one I did. http://www.greateriowareefsociety.org/tabid/78/aft/24231/Default.aspx I used egg crate, Black pond foam., fiberglass resin marine grade poured sand over the resin let it cure. The black pond foam isn't toxic. I didn't seal all of mine and its fine. I am not sure about any of the other foam. You just have to let it dry all the way in the thicker parts of the foam. I let mine dry for a couple weeks mainly because of time constraints. I didn't use any zip ties to hold the rock as the foam held it in place all by its self.

 

I would also like to know what kind of epoxy to use.

 

I used the great stuff pond foam found at Menards. I used z-poxy which can be found at bass pro but I purchased it on amazon as it was way cheaper.

 

I used z-poxy because it says drinking water safe. It's also what a lot of others I had talked to used without any problems.

 

Yes that's the one. One bottle is pink and the other is black.

 

If your not in a hurry and don't mind letting it cure in water for a few months you could use Portland cement and dry rock to make your wall

 

need to becareful using tat great stuff or any foam. That stuff is very boyant and I know a couple folks had some trouble wit their walls floating when they were done.

 

If you use the mortar from marco rocks it will never float. Sets up in hrs.

 

I put bigger rocks in the foam never had an issue of floating .The foam holds the rocks in place I used some pretty big chunks on parts of my wall and it hasn't floated or moved. If you use small pieces of rock it will probably float like rubble. I used a mixture of rubble and bigger rocks.
