New scrubber design contest

Winner! GEDXIN on the PNW forum:

"a new slim-profile submersible upflow algae scrubber. Probably your evolution of the DROP series? Function: air-driven upflow (we provide the air pump) tumbles sump water past growth surfaces lit by red LEDs. Fully underwater so it can't overflow. Beveled top cap that acts as a bubble/splash deflector and directs escaping air out a top slot. Placement: designed to fit narrow sump chambers where a standard DROP won't. Maybe multiple sizes for tanks up to ~50g and ~90g. Color/Material: Matte black, ABS"

2nd place: Garrett Keller on Facebook:

"it pulls flow in through the bottom because of the notches cut out on the bottom. Those notches would allow flow in case it comes in contact with a flat surface. I'm guessing internally it's designed to be used as filtration. The overflow at the top supports the idea that it's bottom fed for flow. I also believe it'd be a great design to incorporate a light vertically and a havestable mesh surround for nutrient control. I could see this used for specific applications like being placed in an all in one chamber or stand alone in a sump"
