Home depot has alot of pond pumps that are good for that.
Not sure about what size you would need though I'm sure its not the largest or the smallest. Maybe around the 140 range.
GoldenGoblin Reviewed by GoldenGoblin on . good small submersible pump? Ok I am starting my own small (3-5) 5-gallon bucket hydro/aero system. What is a good solid basic pump to use? I was looking at little giant brand but I am very open to any out there. I really want your opinion. I am looking at 2 or 3 spray heads inside 3-5 (5 gallon) buckets - all coming from a source resvoir. Any one have any input for me? what do you use? Rating: 5
