I have spent more on sinking line than I care to admit. Actually, I have purposely never added it up just so I don't have to know how much. If I had it to do all over again..... I would do it all over again. I wouldn't cheap out on that. Just seems like asking for more problems down the road to me.
wbuffetjr; I bet I could figure that out for you! LOL
dirtrider88, save yourself the headache, time spent and money lost doing the make your own sinking airline. After a year or two you will pull it out of the pond, throw it away and tell your wife to kick you you know where right before you order the self sinking line like you should have in the first place.
The 1/2 ID line will be plenty for the 375' run. The Gast 0523 rotary vane pump will be plenty to run the 4 diffusers PROVIDING THE SPECS FOR THEM SAY THEY NEED LESS THAN 0.7 CFM PER DIFFUSER TO OPEN.
BUT, my biggest question is "What is your goal for using the aeration system?"
