I think at 7 CFM it is ok for shallow ponds. I would just be interested to know how much volume it loses at different depths. For example we have a linear compressor with a max volume of 5.1 CFM, however at 6' it is already down to 3.5 CFM and at 8' it is producing only 1.6 CFM. Can you see the jump in volume loss from 6' to 8'? Has the manufacturer put on any literature on how much volume it produces at different depths?
I am glad to know you never had a fish kill or any significant problems with your pond. However, I would be very cautious of advising someone to implement a system like this with out having more information on the volume it puts out at 12'. Especially after someone spends a lot of money on stocking the pond. I know we all want to cut corners and do thing as cost effective as possible, but sometimes in the long run it can end up costing us more.
Well I don't need that much CFM cause my fine bubble fusers work from .5 cfm up to 5 cfm each. So I only really need 1.5 CFM to run all 3 of my fusers. I am not just throwing this out there. I have been running this pump for 3 years now and it's a great setup for 350 bucks. Sorry if your offended by that but there are some do it yourself systems that work and work well! I beleive this is one of them. I have never forced anyone to do anything. My suggestion is what it is a suggestion for a system that works well for the guy who don't have much to work with. It's up to them if they want to use it. It doesn't take much cfm or air pressure in a 8 to 10 foot pond to create the flow you need if your system is made correctly.
Here you go check this link out. RoadJoker22 made the same system and is using it at 12 foot no problems.
