Hello, I have learned a lot by checking out the numerous threads but now I need some specific advice. I am redoing a pond in my parents backyard that I did about 7 years ago (with less knowledge than I have now). The pond is 14.5' x 12' x 2'. What I need is for you more experienced users to take a look at the equipment I am planning on using and let me know if there are any major problems that I may be about to create. The first question that I have is is it possible to circulate a pond too much?Based on internet calculators the pond will be roughly 2,600 gal. I know that you want to circulate the entire volume at least once an hour, but would a pump that has a max gph of approx 6,000 gal be counter productive and cause problems. Here is a list of the equipment I plan to use: Pump- Dolphin Amp Master ES series ES3500 or ES5500 (depending on the answer of the above question) Bottom Drain- 3" or 4" (I am not sure which one. I would think that the 4" would be better but then is one enough) Mixing Eductor- (How many is optimal?) Skimmer- Atlantic PS4500 Waterfall- BF1250 Thanks in advance for any advice that anyone can give me.
