I'm not an aeration expert but have an bottom diffuser aerator.
Your shallow depth stands out. I wouldn't think there would be much if any stratification in a 6' deep pond in S. IN. Bottom diffusers are usually better for ponds deeper than yours. There are some shallow water bottom diffusers out there now though that would be worth a look.
What can you expect? Well, I saw clarity increase within a few days. Some pond owners have actually had their clarity reduced due to turbidity or algae blooms from nutrients released.
Muck reduction from bacteria and/or aeration results are all over the place. Some people see great results some people see none.
I'm pretty handy and frugal. I seriously considered and researched building my own system. After estimating material costs, considering the expected end product looks and function I bought a tested, proven, well reviewed system. I estimate it probably only cost about 25% more than what I could have assembled one for (not including my time)but I feel I ended up with something that looked better, probably functions better, had a warranty and customer support.
