I didn't like the look of my heater and intake for my pump so I whipped up this corner cover. Pretty straight forward
2 pieces of acrylic joined with Weld On
Drilled at the bottom to allow cooler water to enter
Painted with epoxy enamel
Siliconed in place
The heater is right beside the intake which should work well as it will pick up the warm water and run it through the discharge.

This was my freshwater 45 that I'm just setting up for salt.
