I too was wondering about powerheads...being a novice!
Do I really need one in a beginner 30 gal
. planted community tank that I plan to set up? The LFS
tried to sell me one, but I decided to hold off until I researched it a little more.
Filther will be a EHEIM 2213 canister, lighting I plan to start at about 2 WPG
. Fish and Plants not yet determined - but easy, fun and hearty for the first learning period.
P.S. How would you determine dead spots in the aquarium?
