Water changes

[moo33284]

Awesome! I made my own sump with a huge 30g tupperware bin instead of another tank... The first part where the water drains in has a sock it goes through first, bioballs and phosphate sponges all contained in a tall tupperware container. that water pours over the top/through holes into a shorter container containing thick sponges. The water from that compartment drains into the last part through holes in the very bottom (so it has to travel through the sponges and doesn't just overflow and bypass them) and ends up at the pump. I hope this makes sense....

Think I can put a fuge down there at all? Maybe in the middle one where the sponges are? Or should I just go with a hang on the back fuge?
