I didn't think that a venturi would work for my set-up because peristaltic pump output is too low. I want the dosing pump for the main pump just as it is because I am metering out the amount of water that comes from the main tank and goes into multiple plankton cultures.
I talked to Bulk Reef Supply and they thought that my idea world work but they really had no idea for sure. I was going to go ahead as planned to test it but this wall clogging issue sounds like something that this design might fall victim to.
Then I thought about those drippers that are used for intravenous medication.
Perhaps I could build something that worked like that but just a little different size. Would this be a lot of trouble that would not get the results that I want either?
