Which size return pump?

hi im planning to make a 55g sump for a 55g tank up to 125g tank. i like the mag series pumps but which one for a sump/fuge this large?
thanks

 

anyone?

 

I have run the Mag 3, 5, & 9 for a while...I find that they work well. You will need to allow for maintenance of these pumps as the impellers need cleaning every 3 to 6 months.

For my current system, I opted for the Reeflo Hammer head pump... I chose this for the reduced maintenance activities, external configuration, and lower power consumption...It is mounted on a 55 gallon sump supplying the 120 gal display tank and 30 gal refugium...as well as all filtration...

 

I am not a fan of Mag pumps due to heat, power consumption and noise issues but I would think something like an OceanRunner 2500 or Eheim 1260 would be perfect, comparable to a Mag 7 but better pumps. The key is going to be the size of your overflow though as it will gevern how big the pump needs to be.

 

ok thanks to both of you umm i have a eheim hang on overflow but not sure on how many gph.

 

I always oversize a pump to account for future additions to the filtration. It's easy to dial a pump back with a valve but impossible to get more gph out of a undersized one.

 

I just about said the same thing to someone last night in a P/M and using a ETSS skimmer get a large pump and valve the skimmer then run it all on one pump .

 

Has worked great for me. Less pumps means the ol lady doesn't have the electric bill to **tch about any more.

 

This is the thread I have been looking for. Return pumps!!!!!!!!!!

 

Its everything you ever wanted to know and then some LOL
