If it's about fish in general, or it's a little bit random, then this is the place to post it.

			This is a stupid question but how do you calculate turnover rate for a tank. Lets say I have a 30 gallon tank, a powerhead at 400 gph. What is my turnover rate per hour? thanks

			In your case: 
 
400 gph divided by 30gallon (400 divided by 30) = turnoverrate of 13,3 gph
