aero pump problem/question

Made a system today using a rubermaid storage tub, pvc piping with 23 nozzles, drain, and a bucket below with a 515 gallons per hour pump. The nozzles only shoot about 2 inches into the air, will not reach yogurt containers suspended in 3 inch holes in the lid. Obviously I need a larger capacity pump, but how much? Do I guess and get a 550 GPH pump, or do I go all the way to an 800 GPH pump? I thought the 515 GPH would be enough, had it left from an outdoor water feature where it fed a 2 foot high fish sculpture with a 8 inch high spout coming out of its mouth, so had it already. Any suggestions on how much larger a pump to buy?

Go big to grow big with lights and air handling equipment for all growers. For hydro go big on air pumps and submersibles. I've seen 30 site cloners with 20 or less nozzles using 900 GPH pumps.

You need to reduce the amount of sprayers and/or increase diameter of feed line. I run one sprayer per plant.
