Internal Corner Overflow, with 1 each 1.5" drain and it has 2 each, 3/4" returns. This is my first tank so wanted to keep is simple. I will try to get more pics later tonight. They gave me some white sch 40 pvc pipe and fittings with black LocLine and the bulkheads that had a slip connection. I replaced that with Black Sch 40 Pipe, Grey Sch 8- fittings, and double threaded bulkeads. It turned into a project when i decided I didn't like seeing the white at the top of the overflow. It will be hard to get pics in the overflow area as the ceiling gets pretty close, I can get in there for maintenance if I need to for some reason but its pretty tight.
I personally am very happy with CTC, I will say that you should be sure they finish all of your edges to your liking, I think in some cases they could have done better with mine especially on the glass top hatches as the tank has a full glass canopy, and there is some spider lines in the caulking in the top bracing, again for me not an issue but I have heard others complain about it.
I have had the tank since August, but haven't put water in it yet...so assuming it holds water, I will be very satisfied and would absolutely consider buying from them again. Also, they warranty the tank for 10 years if they build the stand.
