@soxfan the way I look at it is the aerator running 24/7 isn’t going to hurt anything and I leave mine going year round. Active fish need a good supply of oxygen and expel a good amount of carbon dioxide so the aerator is only going to enhance that gas exchange which is a good thing.
The skimmer really only filters debri off the surface. The main mechanical and biological filtration will be done by the biofalls so you should definitely leave it running 24/7.
Also, we’d love to see pictures of your new fish. Shubunkins are my favorite goldfish!
Will do! I will get pictures tomorrow
