Epoxy for rock wall

[Clown Fish 39]

Hello every one, I was thinking about making a rock wall for a ten gallon tank

I was wondering if I could gorilla glue epoxy?

It was the only epoxy that did not say not for aquariums

also it said it released no toxins when dry

also the only great stuff I could find was big gap filler , it has a

high expansion rate and comes out black?

Do you think the epoxy and foam will be okay?

Thank you very much

coat the foam with a epoxy resin.I used the bondo brand when i did one

so the foam really wont effect the tank if you coat it with epoxy?

where did you get the bondo brand?

The black pond foam found in the garden section at you local big box hardware store works great. No need to use epoxy on that even if you do cut & trim it.

 

The window section will have the cheaper great stuff foam. Make sure theres nothing like anti-mildew stuff added to it. I've also seen it at end isles at the lumber areas

 

For epoxy, I went to a model railroad shop and picked up a few packs of the 2 part epoxy. Forget the name but I believe its the Bob Smith Industries product. Ask the clerk, they know.

 

with the great stuff foam you MUST epoxy any and all exposed foam.

 

note: the black foam is more expensive (around $15/can) but the other route (~$3/can great stuff and ~$8 for 4oz epoxy) you may spend more (depends on wall size and how you apply the epoxy).
