75g sitting on a 4 foot stand.
Large section for skimmer and bubble trap. Over/under/over baffles each spaced 3 inches apart (made a good little refugium before I added dedicated 20g), then another large area for settling and pump section. The large pump section was good for handling evaporation but since the ATO really not needed.
Have the tee off the return also. Plan was to place a multiport manifold to feed things like CA reactor, Phosban reactor, skimmer, etc. Just ended up threading in a 1/4" JG off the 45° fitting for the CA reactor and a MJ1200 for the skimmer. Still think a good idea but probably will never do.
