Water flow Question?

[SSpiro]

Any good reads on water flow?

I have my return on the left hand side of the tank.. where is best to place my heater and powerhead? Should I place on the right hand side?

Place em anywhere you want just make sure you have enough flow for the corals (10x turnover is a guideline).

OK. Stupid question. How do you measure turnover?

[Fish_wiz2]

Take total gallons x 10 or whatever you like an ex. mine is 40gals x10=400 gph needed for a 10x turnover.
