I am going to have a 90 gallon tank soon. I was wondering what part of tank are considered as high/medium/small flow if i am going to put 2 of my powerheads (a 850 GPH) from each side of the tank. to make a circular flow
I am thinking high would be very near power head and then medium probably at the middle of the tank and low would be the end of the tank. But i am not sure if 2x850 GPH is best or I need higher or lower power head. I have lots of LPS that requires medium to high flow, but not sure what is consider medium or high for them.
Thank you for your helps
