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.

The depth of the venturi depends on the amount of pressure that your pump can produce. If the venturi is too deep it will take too much pressure to pull the oxygen down the standpipe on the venturi.

That being said, you are way better off getting an air pump and putting several high quality air stones in your pond. It will increaase your DO levels much better than a venturi.
