I know I'm kinda shooting off in a tangent, but how about taking two pumps and a timer that alternated sequencing on the pumps and then figuring out either the volume needed for alotted time or duration per volume given and created a sort of sped up tide pool. It would be great for biological filtration. Not as efficient as a typical wet/dry but still might be cool. just curious.
The first tank is an internal filter that a guy did.
The second pic is from something that I did similar, but I didn't completely get rid of the HOB. I took a 20g long and put a partition about 3" from on end and then made a tray/ramp that collected the water from the HOB and diverted it to the other end. In the partitioned section, I placed foam in the sections cut for overflow and then put nylon scrubbies in the rest. worked quite well until the fish out grew the setup.
