do sumps need a light

Where did you want to put the macro?

I was racking my brain as to who told me that. Thanks for chiming in.

I used a very similar sump to the one you have and i noticed it was best to just add a baffle before the intake chamber.
It helps keep crud from reaching your return put, allows you to lower your water level in the sump, and the chamber can easily be turned into a fuge chamber.
