Hi All, I need help figuring out where to put Venturi in pond. How deep? All the research I have done gives conflicting advice. I looked up diy but found a white pvc 1.5" at AE for $11.00
I only get one shot gluing it together and I need to do it right. What size pump is ideal?
I have a two tier pond. Weir is out of commission till I figure out what to do about my leak.
5000gal 4.5-5 feet deep (sloping.) Please advise,

Your experience and expertise is appreciated.
