hi, guys i finally come up with this new idea. I am using two powerhead for the DIY filteration for my 100g tank.I got this 60litre Engine oil bucket from my friend. will turn it to a filter . with filteration material include
1st layer sponge.
2nd layer scrubber
3rs layer ceramic rings
I am using intervert power head means suction part upside and exit side wize .
but not sure with the powerhead speed.
can any one explain what should be the speed rating of the return powerhead and the one which pulls water into the filter.
