I'm putting a large aquarium in my shop. I already have a air compressor that I use for my pneumatic tools. I'm thinking that I'll split off a separate regulator to use as an air source for fluid medium in my sump filter. My question is; Will the air quality coming out of that compressor be okay to use in my sump or will it be filled with harmful bacteria or heavy metals from inside the compressor tank.? I don't know, does anyone know?
