I wanted to make a new Sulawesi tank but I didnt want to buy a canister or HOB filter. I wanted the tank to have a cleaner look as well. I like the 12" cube size, but i wanted more surface area for the shrimps/snails to crawl around on.
i ended up deciding on making an overflow, with a waterfall type spout, all powered by a single 65gph pump.
heres the initial design of the built in filter area in the back:
and how it looks in real life..... the bioballs arent near the heater like the picture. I dont want them to melt, i put a bag of crush coral on top of them to keep them down:
the current flow.. the overflow, and waterfall spout....
this is how it currently looks (white slime on the manzanita is kinda gross):
approx 7.5 gallons
substrate: eco complete
rocks: cobble stone
current inhabitants: 2 african dwarf frogs & nematodes
when the tank is clean, i'll put in my cardinal shrimps
