![]() Have a 45g with 10g sump and 5-6ft head.
Was thinking a mag7 or 9.5. Wondering if anyone has one for sale used in good shape? Thanks |

![]() I just picked up a Mag 5 from JL for $68. They have a special on them.....15% off.
My head height is just under 4' with a 25g sump. I'm hoping turning over the tank 7x is adequate opposed to using a Mag 7 with a turn over rate if 10x. Good luck! Last edited by byee; 11-03-2013 at 01:35 AM. |

![]() You could always put a valve on it and tone it down too with a more powerful pump. This way it gives you the option to throttle it up if needed.

![]() Just put a piece of foam rubber under it. I ran a mag9.5 for 5 years and it was silent with a pad under it, other wise the vibration goes through the glass bottom of the sump and can be loud. I had mine throttled down (discharge side only) for the five years with no issues, the new owner has no problems with it either. With a larger pump you can also tee off of the discharge and use the extra flow to run reactors or divert flow to a refugium, etc.

![]() If you want to valve off a mag put a tee fitting on your return with a ball valve and open it up letting the excess flow go into your sump

![]() Quiet ones suck IMO
Better off with a sicce or eheim

![]() I'm of the school of thought that high sump turnover rate is NOT a great thing. I like to have my dirty water go through slower so my skimmer has more chance to skim it clean before its pumped back up.
Besides, faster turnover equals bigger pump equals more electricity used 24/7 (very inefficiently). A Mag 7 uses 70w, whereas a smaller pump will probable use 50 or less. The 20w extra only gets you 200 gph through the return but will get you 1400 gph + with decent powerhead. Just my opinion. Anthony

![]() Yep, I've got the pump valved and slowed down. It's not the flow I'm worried about it's the fact my whole tank vibrates with this thing and it sounds like a blender... I'm looking for something that's quiet, not something that I can hear 2 levels down :-/
Those eheim pumps are wicked expensive. However the sicce pumps seem to be reasonable. Are they reliable? |
