Great Stuff Pond and Stone?

[RadReef]

Does anyone have experience with Dow Great Stuff Pond and Stone? I'm wanting to use it to do foam background. Here's a description from their site:GREAT STUFF™ Pond & Stone is the easy way to create beautiful aquascapes and hardscapes. By expanding to fill gaps and cracks, our foam filler helps direct the flow of water in waterfall, pond and streambed construction to the exterior of the water feature, instead of between or behind rocks. The foam’s black color means it’s easily hidden among the stones and shadows. It creates a permanent, water-shedding bond to stone, rock, masonry, concrete and most other building materials. You can construct the stunning water features you’ve always envisioned, without harming plants or fish.

I used it on mine. When I was done I covered it with epoxy and sand so it would blend in better. I havent heard anything good, bad or otherwise about it. AFAIK its completely safe for fish and its made to be submerged, unlike the normal greatstuff foam.

just remember that it floats...a lot

Thanks for the comments! I figured that it would work for aquariums as in the description it states that it's safe for fish. I also heard that it floats. What I want to do is put it in-between my marco rocks and build structures that look like a single piece of rock. Plus, my wife is doing a full foam/rock background. I definately want to epoxy it and cover it with sand.

Hey, thanks for links!! I have an Ace close to my house. I'll have to shoot over there and see if they carry that product.

for the stand alone/ column pieces you are doing, you shouldn't have a floating issue...trim away any excess with a serated knife, drill, wire brush, or whatever. you can drill holes and what not to make it look more natural if you like. As for the wall, use a lot of rock...or a lot of adhesive on the glass...or both. Mine is form fitted, but more or less free-standing. Oh, and my local HD and Lowes stores both have the foam if Ace doesn't.

For her tank we were thinking about using cell crate (what's used in flourescent lights in drop ceiling) to build a frame and then zip tie the rocks to the background then marine silicone that into the tank and then add foam in-between. Mine will be a system of towers and an arch. That's a good idea though about drilling the foam and ruffing it up so that when it becomes coraline covered it will look natural.

Thats how I did mine. I have a couple different caves and contours built that way. When it was all done I siliconed it all to the back to keep detritus from collecting behind it.

I started using a dremel to shape down the foam so it looked more like rock instead of the round blobs it normally makes but found out a needle nose pliers worked better. Just randomly stab it in and rip pieces out. It gives a nice jaged look and gets rid of a lot of the buoyancy. I have 25 pounds of Marco rock spread on 2 pieces and had no problems with floating before I sealed the parts down.

Ill get a full tank shot for you in a few minutes. After a month and 250 views it was obvious there was no interest so I stopped updating. If you have any questions feel free to PM me.
