I've been running a diffuser in the shallow ends of the two ponds with fish but I'm still a little concerned. Two reasons:
About 18 inches of snow cover and I went into winter with significant submergent weeds on one half of the pond. I will temporarily get my D.O meter back from Scot and do some testing. If I have to I will put in my surface Kasco aerator and open a hole about 30 feet wide with it. I did that two years ago when D.O levels were dropping but I didn't run a diffuser that year.
