I didn't want any ph's in my system, so I designed completely around CLs. I have two CLs, but each one required a big 2" intake...so maybe I traded large strainer intakes for PHs.
There are 4 outlets in the back wall...and 4 outlets on the bottom of the tank. Mostly, they are difficult to notice. In this photo, you can see:
- 1 of 4 back wall outlets on the far left
- there is one floor outlet hidden in the Xenia on the far left
- there is one floor outlet behind the rock, just below the yellow tang
- you can see a floor outlet in the left side cave below a red sponge
From the front, both intakes are hidden...but you can see the reflection of the one on the left.
