JD,

It depends on how deep your pond is if your Kasco will do the job of breaking down nutrients all the way to the bottom. Surface aerators tend to only go down so far (I think 6 or 8 feet -- Mike can clarify this).

If your Kasco will draw up water from the bottom and it is not too deep then it is fine. I have seen one surface aerator that draws water up in deeper water with an extension tube. Not sure what brand it was.

When it really gets hot I sometimes run my diffusers only at night to keep water warming down. If you are not feeding with pellets and your fish density is low and your pond is fairly large than the breakdown of fish waste may not be as crucial either. I'm feeding a couple pounds of feed a day into this small 1/12th acre pond and that can add up over time. Just as last year I have a build up of filamentous algae on the rocks down a few feet, and it is starting to break loose and float up. However, if it is the same as last year, I will net it off the surface for a few weeks and then it just vanishes. I think it may be the bacteria I add finally multiplying enough, and competing for nutrients, or the water is slightly warmer for optimum growth of the bacteria over the algae. Or both. I don't know for sure.

One lure that is deadly on trout and facilitates catch and release is a panfish jig with a tail that flexes alot. I just cast it out and let it sink to the bottom on a tight line just in case a fish hits it right away. Then I bounce it in and the hit is unmistakable.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
