Adding Eggcrate to Inside of Tank

I have no more room left in my tank for anything. I would like to maybe add a few frags or SPS Montipora. If I buy some eggcrate and cut it how would I attach it to the inside of the tank? I was thinking a little piece maybe 10x5

 

If you Google Frag Mags you can find magnets that you are able to attache coral to. Will look a lot better then having eggcrate in your tank. JMO

 

I would then glue my frag right onto the stone magnet inside? I never though of this. The only thing is then your piece might be sideways.

 

I made my frag racks out of eggcrate, superglue, zip ties, and big suction cups for walmart.. never had one come off..Let me see if I can find a pic....

 

here's one...

 

and a better one...

 

I built a 3 layer rack using 1/2" PVC and fittings. No glue required anywhere because the PVC fittings were nice and tight. Also allows me to add more layers. The pipe hangs on the edge of the tank with more fittings and the two sides are connected outside the tank with another piece of pipe for stability. I already had the egg crate. The pipe and the fittings cost about $6 total.

 

Looks sweet......

 

Thanks. I made it last weekend. I'll probably make a few mods. I'll probably ziptie the eggcrate down to the supports to keep it from falling off. I also realized that the top shelf will be out of the water during water changes.

 

I just took an old mag float and attached the eggcrate onto it using epoxy. Works great
