I am setting up a sump on my 210 and i wanted to know what turnover rate you guys are using for your sumps. I've read some people using 10x and others using 3x. Looking to buy a pump, and was wondering how big of one to get. Thanks all.

DeLgAdO;473304; said:lets say your tank is 200 gallons
if you want a 10x (times) turn over rate
just multiply the 200 times the number of times you want the pump so "turn over" the tank
lets say you want the pump to turn the tank over ten times
thats 2000gph (200x10)
so you would need pump with a 2000 gph flow rate to do the job
1000 if you want it to do it 5 times.
cockroach;473333; said:turn over means the whole tanks volume going through the filter. if you have a 100gal tank and your filter is rated 1000gal. then the tank turns over 10 times. ie 1000gal (pump flow rate) / 100gal tank size= 10x (times).
another way to put it is how many times you could fill your tank using the pump if it were pumping water from a limitless source. 1000gal pump could fill 10 100gal tanks in an hour.
hope this clears it up a bit.
