looks good, glad you took my advice regarding the built in tunze holes in the overflow.
if you are running a CL or even for the return i'd plumb the lower returns on the inside of the overflow box down. that way they can get behind the rock work and keep anything from accumulating back there. It would really prevent dead spots.
You can purchase new intake screens for your Tunzes. It's not cheap (roughly $100 for the pair), but your opening will go from 50mm to 63mm. Your flow pattern will be much wider, and aiming the Tunzes will be less critical.
Am I messing with you? No. Keeping a moray in a tank that size in inhumane.
:hammer:
I forgot to add. The new larger intake screens are designed for the Tunze 6200. They are compatible with all Streams.
