Well I'm out of room...... ALl thats left is the coraline encrusted back glass. I was thinking of getting some 1" acrylic cubes and glueing them onto the glass. If I can get them to stay I would imagine in 6 months they would be coralined on perminiatly. So if I mount corals to these, the only downside would be the coral probably growing onto the glass. (NO BIG DEAL TO ME) And Second Id have to mount them low enough as to when they do grow, they dont look like corals floating off the back glass. Let me know if anyone has any ideas or critisms about this.
