I wouldn't lower the water level unless you have your sump designed to trickle water over them and keep the exposed balls constantly wet. Have you seen a wet/dry filter in operation? These have trays with many holes in them that drip water over a large surface.

Yes, that's how my sump is designed.

Keep in mind that having an adequate amount of LR in your DT will also provide space for the anaerobic bacteria and help with nitrate reduction.

Great! Can't wait!
