Eheim 1250 enough?

bestreef · 11/01/2011, 11:46 AM

Is Eheim 1250 (317gph) is enough flow for 70g sps only tank with few fish?
The tank dimension is 30"x30"x18" with 30g refugium sump. Please anyone advise?

Thanks

I think u should go with the 1260 or even with the 1262, i have 1262 on my 57g but my return feeds my GFO and carbon reactor, and i think that the 1262 is little small for this, so i think the 1250 will be way to small for ya

I agree that the 1250 will be too small. It may pump 317gph at 0 head, but by the time it pumps the water up to your tank it's probably going to be pushing less than 200gph, maybe a lot less (depending on your setup). I would go with a 1260.

Agreed, I run a 1260 on my 50 gallon tank and would not go any smaller. On a 70 gallon tank, the 1262 would probably be a better choice, but I think you could get by on a 1260.

I tried a 1250 on a 30 gallon over a 25 gallon sump and thought it was way too little flow.

Running a 1260 now and I think it's a little high but well within reason.

Yes, 1260 for sure. When I test my 1250 after head loss I was doing about 125gph. When I upgraded to my 65g I moved up to the 1260, which I now use as my return and I T it off to run my GFO reactor.
