How much gorilla glue did you use?

I used a throw away brush and brushed a heavy coat (like painting), then applied excessive substrate and let dry. Then shook off excess substrate. Gorilla glue expands somewhat, so it seems to work great. A big bottle (the $19 one at HD) easily was enough for my 120. Had about 1/4 bottle left when done.

i just ordered some BSI epoxy and it should be in within the next week days. Just finished putting the smartpond foam on and i didnt get all of the egg crate covered because i thought it was going to expand all the way to the edges. I dont know if i want to get another can or just cut the excess egg crate and silicon the edges but there will be a couple spots were you can see the glass.
Did you silicon all edges on yours? I wonder what would happen if water gets behind the egg crate.

Great Plains epoxy???
Great Plains epoxy???
Has anyone heard of or used this epoxy? I ordered some BSI 20 min finish cute but i don't know if it will be enough and they had this type at my local hobby store.

I don't have any experience with BSI. I have used Gorrilla glue and also Locktite two part epoxy in the past with fine results. I am sure the BSI will be ok.
I never have tried to totally seal the wall with silicon as it would be about impossible. Also I have never had trouble and I am sure water is behind the wall as I just glob the silicon on in places to hold the wall. I also rarely go all the way to the bottom because the rock work comes up on the wall.
Don't overthink this, it will be fine

Haha yea I'm sure im just stressing over cause I don't want to do it wrong. This thread has been awesome and I wouldn't even thought about doing this if it wasn't for this thread.

When putting new sand on the foam with epoxy. Did yall rinse the new sand first or through it on there?

yes a few ppl have done that but can't remember who it was
So a few pictures of my current under construction build. Marineland 5 gallon portrait tank, think the tall profile will look killer. Materials used will be pond foam, eggcrate, zipties and shaded epoxy. No real rock in this baby and I will have 4 sides of adhesion via silicone including bottom.

I built a wall to hide my overflow box and my return...not a full wall, but a partial one that arches across the back. Entirely foam. Sculpted in foamular and covered with black pond foam and sand.
Here's my build posts on it... Completely Foam Wall.

That little worker in the tank has been busy. Looks good to me!
I will be using foam in my oyster reef project, but haven't moved on it lately. I have some work to do with the rock still before I apply the foam and finishing touches. For me, the foam will be to attach some of the oysters to the base once the base is done curing (DIY Rock). The foam probably won't be too visible in my tank, I'm using it as an adhesive mostly.
I am also building a freshwater native american stream tank (darters) and will build a partial wall using styrofoam cut and shaped, and covered with Drylok. I will be using silicone to glue it to the back of the tank and bottom along with natural rocks from local streams to stabilize the structure.

Do you get the benefit of rock with all the pockets of air in the foam?

I mean, will beneficial bacteria be able to grow and use the pockets of air in the foam the same way they do in rock?
