Generally, subtracting 25/30% will give you a reasonable estimate. If your set-up requires exact or constant flow monitoring then a meter might be necessary.
http://www.purifydrinkingwater.com/Product-A-DF-086.htm Yes "actual" flow rate is a better indicator of how your filter is doing but for me, approximation ('ballpark') will suffice. "T"
(Oh! BTW great flow on that FX5. 925gph mfgr. - 660gph actual = about 28% difference) approximately!!
I should of been more specific, in this thread the mfgr is useless... you agree?
But it is useful as a reference when choosing a filter for your tank size and species kept, but noobs need to realise manufacturers will do whatever it takes to get the highest output possible so they can quote it on their box(test them with very short same length tubing, no media, low head height etc.) so once you add media and start using different length or longer tubing(canister) the mfgr goes out the window...
were you being sarcastic about the fx5 flow rate? i can't tell
NO! NO! NO! Not at all neighbor. 660gph is a very good flow. My point was on the 28% of the mfgr. stated 925gph. I had previously stated you could be 'in the ballpark' by estimating a 25/30% difference from whatever the mfgr. stated & you proved my point is all. You'll never get sarcasm or ill will from me cause that's not my way. What size tank do you have that monster on anyway? How many turns? "T"
