Lets have some discussion that may clear up the confusion for newbies or just for the halibut.
So often I see posts on RC: I have 900X turnover rate in my SPS system .....LOL It's always some guy that just put a pair of tunze or the like in use so he does the math @ 40,000 GPH in a 75 ....
or you see "well my return pump is a xxx and 3 magdrives on closed loops and ..etc so my turn over is ..."
Anyway if this were turnover those tanks would look and sound like a toilet flushing.
Turnover = the number of times you pump your total system volume to the display and back to the sump. (10X is a good rule of thumb depending on system size and skimmer design)
Flow= much more complicated, lots of people just take the rating of the pump and divide by tank size and call it x/ hour. I think it really has as much to do with your aquascaping and type of pump as it does rating.
And !... service schedule....If you put a 500GPH power head in your tank 6 months ago how much flow do you have now ? NOT 500!
any way maybe this sounds stupid ...Maybe too basic...but maybe it will make for a good discussion.
