Note to all. The EcoPlus7 air pump has an air pressure rating of 5.1psi. This means it will produce air down to 10ft deep maximum. Operating at the 10ft depth forces the pump to operate under maximum conditions (stress) while it is running. IMO this will shorten its useful 'life span'. The pump will last longer if it has to only push air 6-8ft deep. Generally the deeper a pump operates the less air volume it is able to produce compared to the 'open' air flow.
Mr. Cody is correct as he is most of the time! This pump is a decent pump and it works for me in 8 to 10 feet of water. Keep in mind what I just said. (It works for me) that doesn't mean if you go out and by this pump it will work great for you too?? YOu just never know until you try it. The system I put together is just that put together by a rookie (myself) for me, I have no obligations or money involed with Eco 7 so please don't think that there arent better pumps out there cause I am sure there are. I guess what I am trying to say is just like Mr. Cody says (It all depends) on your situation and everything else pondom. So when I say this pump has worked good for me I have no ties at all just letting everyone here know how well of a job it's done for me and that it COULD do the same for you. I have about 350 bucks tied up in my whole system. Heck most pumps alone are more than that so for the small do it yourself pond guy it's worth giving it a try and see what happens.
thanks,
