Good thought. I built the structure with hiding spots in the center. Here is shot from the top and a shot from the side.That looks really neat, but doesn't it greatly limit the hiding spots for fish?
Yes. Black aquarium silicone. Seems to hold so far. Fingers crossed.did you bond the shelf to the glass using silicon?
I bought a bigger piece and cut it myself and drilled the holes. The rocks are attached to the acrylic piece with silicone to compensate for the uneven surfaces. I even sanded the acrylic to help create a rougher surface for better bonding. Rocks on top of rocks are attached with some silicone, some glue. After things dried, I used E-marco-400 to make it look like one rock and hide the exposed acrylic. Oh, and the overhang in the front is an extra piece of acrylic I siliconed to the other one and glued rocks to it. Its like creating a rock sculpture.Looks great! did you make that acrylic piece or buy it?
That would be cool.I really like your idea. Looks really cool! Any plans for some non-photosynthetic corals under the floating structure?
Yes, I agree. My understanding was that the silicone does not bind acrylic because the surface is so smooth so I used sandpaper to add texture and hopefully help it bond better. Fingers crossed. If it starts to detach from back wall, Ill just support it with a rock and learn from my mistakes. If I ever want to take it down off the back wall, I should be able to cut the silicone with a knife or razor pretty cleanly I imagine.You’ve got a fair amount of surface area that you were able to silicone but since silicone doesn’t bond to acrylic I hope it doesn’t cause problems for you over time. In the future you might want to use something like e6000 adhesive.
Your rockwork looks amazing though.
Edit: I just saw the inspiration video and he referenced using silicone and it seems to have worked fine for him. Maybe you’ll be fine too.
