Pump for refuge/sump

Looking for a good pump for my 20 gallon refuge/sump. My tank is 30 gal reef with cpr overflow. Are these any good? http://cgi.ebay.com/ws/eBayISAPI.dl...4361067104&rd=1

You would probably be happier in the long run with something like this...

If you really want to go small look at the specs on this one http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=46312&item=4361033262&tc=photo

 

Out of those, I'd probably go with 700gph Mag. With head loss I'd guess you'd get around 600gph which is probably the max on your CPR overflow.

 

actually the max is 1200 GPH on the cpr, would that be too much ? Keep in mind the 20 gallon tank was made into a sump/refuge 2/3 = refugium this is where the water enters and the last 1/3 is the sump where the water is pumped back out

 

Curious, do you have it so you can control the flow to the refugium itself and have a bypass for the additional flow?

 

you mean like a T valve type thing...well if so no but i was thinking about it eventually

 

diver I think 900 GPH would be too much flow for my refuge but this one isnt looking bad http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=46312&item=4361033262

 

this one looks alright too http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=46312&item=436115531
