Hi al I just got my 2 Hydor Koralia #3's. I am using them in a 65gal tank. what is the best placement for them? I have a finger coral in the tank, and have been trying all day to get the powerheads set so the coral will sway. I'm having absolutely no luck. I have the filter return set in the middle of the tank aiming straight out. The powerheads are on the sides of the tank aiming towards the middle facing each other. This is pissing me off so much help. I know this sounds redicules but I need help with this.
