Roland Jacques · 07/15/2006, 07:26 AM

i getting that 18 LPM = 38 SCFH. the ER rc180 cliams to get 18 LMP. and i no it cant pull 38 SCFH

The RC coversion chart says
28.316846592 = 1cubic foot

im doing something wrong and i cant figure it out, i need some help.

1 Liter is .0353146667 cubic feet.

so 18 Liters Per Minutes is .6356640006 SCFM

.6356640006 SCFM = 38.139840036 SCFH

Shortcut:
Instead of doing the math just take LPM * 2.118880002 to get SCFH

bean, we got the same answer. but it is impossable for that size skimmer to except 38 SCFM without it all turning to foam instantly??

I have an old 8-2 euro-reef skimmer (exact same dimensions as the RC-180) that I put a Sedra 9000 recirc mod on and between the stock feed pump and the Sedra 9000 I am getting 18 LPM.

The body can handle 18 LPM fine.

Where does all your research take place? I would think that a company like ER or (any other skimmer manufacture for that matter) may have just a few more resources than you. I could be wrong, but thats why I'm asking.

I've already posted pics of my ER pulling in 15lpm. Why can't a skimmer like mine (RC180) take in 3lpm more?
