What type of compressor are you thinking to use for the root scape aerator?
Bluegills only will severely overpopulate and stunt in that small 70ft X 70ft pond unless you stock only the males that you can catch and easily recognize during spawning season. Transport 5-8 each fishing trip. Haul them in plenty of water - maybe a garbage can with plastic bag liner. I would not put any more in that size of pond than 35 to then maybe 50 if you feed them high quality fish food as in 40%+ protein.
