return pump

[tinnghe]

i am looking for an external pump that would hit around 1000 gph, soemthing that goes really quiet any suggestion?

You need to know the head(height) the water will be going. Eheim are known to be quiet but the biggest one they have is 900gph at 0' head. I have an Iwaki and Panworld and their both make a humming noise but for external are not that bad.

I am new toward pump what do u mean by head it will sit under my tank in the stand. I actually took a look at the panworld and I think I might get it how long do u have ur for I have a 140 with 40 sump

Like reef_guru mentioned on the other thread you need to know how much water is coming down through the overflows into your sump. Head is the amount of length (usually in feet) that the water has to travel upwards (you calculate from the bottom of the sump to the top of the return tube).

Ive had my panworld for about 6-7 months and its worked fine. But again with external your usually going to have noise due to the fans.

i found that the bulk head is around 1" in the interior, how do u measure how much water flow? i havent set it up yet so i dont know how much water flow down the overflow

I think that 1" is 600gph max, You can also looks a little giants pumps, Ive heard good things from them.

in the tank there are two overflow with four holes together. after doing some research, i found that both eheim and pan world are the good choice that i should get, since you have experience with them, would u let me know how good these run?
so 1200 gph flow?

So you have 4 bulkheads? Two for overflows, and two for return? Are the bulkheads on the bottom glass (drilled tank) or do you have an overflow box?

i have a drilled tank with 2 overflow box that have 2 return 2 overflow.
