kimber your setup sounds a lot like mine. I ran 80 feet of weighted 5/8th inside diameter line to my 3 station diffuser. Not sure of your pond size? , but with the correct pump you can run 2 or 3 fusers. IMO when it comes to making tiny bubbles more the better! Go with weighted hose though you will be happy you did. I also went from my air pump to the weighted hose with about 8 foot of plastic tubing in half inch diameter. I bought a 1/2 to 5/8ths brass adaptor so I could fit both hoses together with a couple of hose clamps.

Good Luck
RC,

Oh one thing you may want to consider. I also put a 10 or 12 inch heater hose I got from Auto Zone on first in front of my plastic tubing as them pumps get pretty darn hot and I did not want that pump melting my plastic tubing. Just FYI.

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
