Baffle installation questions
 

I'm about ready to install glass baffles in my standard 75 glass tank sump. I'm going to have the glass cut so that there is a 1/8" gap on either side to leave room for the silicone. I'm wondering what the best method of installation is. Should I put silicone on the side of the tank first and then place the baffle on the silicone? or should i place the glass in the right place then silicone the edges?

Also, what procedure should I use to install the baffles for the bubble trap? Do I need to do each piece separately? Thanks!

Place the glass then silicon it in place.

get the corners cut or rounded so that on the bottom there will be space for the silicon
