Sounds like it has all the makings of an incredibly beautiful and peaceful aesthetic feature once you work all the kinks out.
The "only 2 aerators" - are they small, ornamental-pond-style aeration stone type (solar?) or is it a system designed for a larger, outdoor pond? A really good aeration system, sized appropriately, makes a big difference from everything I've seen and my very limited personal experience. If you have the ability to post some photos of what you are challenged with, that might help the folks here with suggestions. There are many very, very experienced pondmeisters that navigate these forums (I'm not one of them) that can likely offer up a few pointers in the right direction.
Congrats on your new home and pond! Cheers!
