If you want a pump that is small and easy to modify, a maxi jet comes to mind. That being said, I don't think they get to 600 gph
. This begs the question, regardless of brand or pump, why do you not just use multiple pumps? For example, 3 200 gph
powerheads would be much easier to make shrimp safe, be easier to hide (as there are probably multiple places for each to hide), and ensure better circulation.
