Hello all! I just bought an 100 gallon, 4 by 2 by 2 foot galvanized animal water trough that I will use as a pond next year, and I wanted to know how to keep water temperatures under control for fish...I was hoping to keep it in at least 6 hours of sun a day for the Nymphaea odorata water lily I just bought for it and wanted to know how to keep water temps within reasonable levels (the fish I will be keeping is a very sturdy Greek killifish that can take temps into the 90's and down to the high 30's without incident, but I would like to keep them a tad lower if possible). Would a pump work for or against keeping this water garden's temperature down? Any other ideas to reduce pond temps other than keeping the pond in flower-stifling shade? Thankx for your quick replies!
