okay so i am building a river type tank. here is a preplan layout:
the blue line is the water line
the yellow and green are filter media
the tubing will be 1 inch
and the squares on the right side of the picture will be the powerheads
so the questions i have are
1) will the 1inch pipe be good enough
2) what flow rate should i have the power heads rated at
3) air bubble bar under the power heads or air line connected to the power head air intake
