Just picked up a used MP40w and trying to figure out the best placement and mode for my tank. It is not currently hooked up. Right now, I still have my two modded tunze 6025, mod mj1200, and K4. What do you suggest I keep along with the mp40 and where do I also place these?
The tank is a 90g with corner overflow. I do have about 3" of sand.
