THAT is outstanding. Very well thought out and designed. Keep posting pictures - want to see how you finish.
I really like the clean layout and the killer filter setup. I also like the hardline for the aeration instead of tubing.
Nice job.
I'm with ya on the 'only the sump'. I only brought it up because this build is so clean everywhere else. doesn't seem like it would be hard to smear some more silicone on that thing.
Again, this is a beautiful tank/build, amazing work. I can't wait to see fish in it.
