I am looking for some advice on what type of powerhead/powerheads to get for my 40 gallon breeder that I am setting up. It will be my main display and will have sand, etc. I don't want dead spots but also don't want the sand blown around. What are the favorites and what would be good for this size tank? I need help in deciding what type of powerhead/powerheads to get, how many, and where to place them.
Thank you for your help.
