Howdy.... I just built a smallish frog pond for my garden. There are still aesthetic improvements to be made but before I get too involved with that I'm trying to come up with a cheap DIY way to aerate it. I'm guessing it's in the neighborhood of 500 gallons. It's too far from an electrical power source, but I have a 100 watt solar panel system (that needs a charge controller replaced) and I'm wondering if an inexpensive 12v auto air compressor type pump might be enough to utilize a single air stone. I'm sure they're not designed for continual use but as it would be under almost no load maybe it would suffice. If I already had the pump I'd just hook it up to 12v and check, but lacking one I didn't want to go buy it as I have no other needs for one. Has anyone tried this? I appreciate your input!
