Thank you ,Both , what I needed , NO O2, using a 5,000 gallon pond aerator , per tank , wouldn't know where to start with O2 , and I know it.. 50 gallons of water. per tank , 4 tanks available. 100-150 per tank , if that lucky , very conservative first trip with wild fish . Have to ID each of the little boogers before going into pond . Thank you both , again . .
