You can plan on the 100 delivering ~3.5 CFM at 6' and the 80 delivering ~2.4 CFM at 6' (both interpolated from the chart) If you were feeding 2 discs like I'm using with 2.4 CFM, my guess is you would get similar or greater air delivery compared to my setup. But - I am a complete experimenter here. Compared to the Koi pond folks, there are surprisingly few mentions of linear air pumps on Pond Boss. I suspect that is because 6' seems to be the big cut-off for when it no longer makes sense to use these guys. If it matters, these Medo pumps are MUCH larger than I imagined. Specs are on the Medo site, but the 120 is 16' x 8.24' by 9.1" . I am currently using a kitchen garbage can upside-down as a rain cover until I get the poly laid down - and it just fits...

Thanks for your reply. I will do a survey first to see how deep my pond is in the 2 places I was planning on placing the discs. That is if I need two discs. I plan on running this system just at night. I will use a dawn to dusk light sensor controlling a heavy duty relay. Last edited by passgas55; 06/21/10 03:25 PM.
