Back wall rock work question.

[TheBlackSloth93]

So I'm redoing my 55 gal. I want to do a African cichlid set up. I've never used silicon in a tank before but was going to with this one to make some caves. I also wanted to IF I can. Do rocks along the bak of the tank up the glass. How can I do this. What kind of rocks should I use? Will it be to much weight? Thanks for any help

You can use real rocks if you want i personally wouldnt use real big ones that are heavy. If i did it thay way i would get a firm piece of glass to build it on and use as an insert.

This may help or give another option

I built a backwall out of great stuff pond and stone and attached driftwood into it. It's fish safe and holding, but it's twice the price of the regular stuff, it is black though instead of that sickly yellow/orange color. Just make sure your silicone is the right stuff, you want 100% and not mold/mildew resistant.
