Tank turnover rate??

[150reef]

Was just curious about this, when you hear people say that to properly maintain an aquarium you should at a minimum turnover your tanks water volume 6 times per hour. My question is what is or are the determining factors of turnover? Do you only consider the return pumps output to measure turnover or do you include: return pump, skimmers, powerheads, canister filters etc..?

Thanks,
Jack

That should answer your question.

I think you would include anything that causes water movement in your tank. I have a mixed reef and by conservative estimates I am at 43 times turnover.
