85g shallow & deep FRAG tank to display tank

[Mr Cob]

I was picturing it a bit different than the pic above. With that setup you would have issues with bubbles from the skimmer entering your tank via return.

not if I have the 20g dumping to the sump before the baffles.

Man, thanks for the pics...so much easier. I'm not much of a DIY reefer...maybe in my own amateur way but not at this level.
