Looking for some advice on a good reliable pumps, trying to throw a diy setup together for my +-1 acre pond for a 2 diffuser setup, placement will be roughly 6-7ft of water. Water has no movement, except when it pours and it�s starting to reflect on surface and quality, and I want to get something going before I start seeing livestock problems. I seen a few videos on hiblows, which seem like they last a long time and you can buy replacement parts which is a plus. Don�t really want to spend a lot in electricity bills to run something. Thanks for any info
