As mentioned in the title, I was wondering if anyone knows how well air pumps(the aquatop for example) work in high humidity environments, up to high 80s and low 90s. I've got a greenhouse near one of my outdoor miniponds that has high humidity at night and drops to the mid 50s during the day. and temperatures ranging from 10 to 20(and possibly more) Fahrenheit above outside temps according to the time of day.
