heres a random picture to show how my "dual overflow" is actually just one
and filling it with sand and water
what i didnt get pictures of is the pipe maze under the sand for my ribbon eel.
the sump/dt (known now as the panorama) i was able to get running some time before the rest (mainly due to a friends tank crash and needing space to hold their stuff) you wouldnt believe the free stuff i ended up with that day!
