pump and flow options
Hey everyone. Thought I would get some oppinons from you guys.
I am currently running 2 mag7's as my return pumps from my 55gal sump/fuge into my 125 display tank.
this produces aprox 1400gph at 0ft, at 6-8ft, i have no idea. my idea was to either leave it as it is, put an educator on one of the outputs, or on both the outputs from the pumps, or make one of the mag7s a closed loop pump, keeping the other for a return, giving me, i hope, 500ish gph through the sump/fuge.
or, should i throw a mag12 in the mix, and what would be its best suited job?

I would only use an eductor with a powerfull pump. It increases mixing, but cuts down on flow.

if you want to go the eductor route, you really should use a pressure rated pump, with a closed loop would be easiest too.

well then i guess an educator is out.. what about pump options?
option 1:
1 mag7 for return, 1 mag7 for closed loop
option 2:
1 mag 12 for return, 2 mag 7's for closed loop
option 3:
2 mag 7's for return, 1 mag 12 for closed loop

If you are doing a closed loop, why not ditch the mags all together and get an external pump? You will find the flow to be better, with the same if not less electricity consumption. If you get a good external pump for the closed loop, you coudl even put penductors/educator(s) on the CL

so I guess my choice would be mag 7 return, and none of the above for closed loop.

Personally I would only use one mag 7 as a return, use the other for utility and BACKUP if the first goes bad. For more flow in the tank I would use seio, maxijet mod, or tunzi.

well the 2 i figured was backup, and i am running both of them external right now with no issues so far. I also have 2 maxi 12's running, but they are both at the end of the tank where the overflow is, and i thought it might be better to get more flow..
whats the maxijet mod?
fritz, sounds like you might think i would want to use one as a closed loop? if i dont have to, i would rather not spend any considerable ammount of money, and i know i can get a mag12 for 65, so...

if you already have the maxi jets laying around, I would do the maxi mod. Talk to seamonkey, he has nearly perfected the process, I think, and could give you some insight/pointers.

I have a Mag 18 I would trade you for a smaller one in good shape plus some flow. Not much but to even things out a bit as mine is in perfect shape. (besides for some coraline)

ps if you want to do eductors, I am really happy with how my 125 plumbed out with a single external preassure rated pump which was not to bad on price. I used a GenX 55 and have it split off to both returns on each end with a Penductor on the end of a length of locline for each return. Plenty of flow if I need it but I have it turned down to keep that stupid live sand crap in check. I am not sure that it was blasting at my meeting or not but I am sure someone else would vouge that if you do not want powerheads this would be a good choice on route to go. I run a 1 1/2" drain and it keeps up great with little to no gurgle.

I don't mean a closed loop at all.
I mean run one supply (mag 7)
Have one for spare (mag 7)
Run something in the tank for flow IN the tank (Sieo 1500 (would be my choice)).
Unfortunatly, there are a million ways to skin this cat.  |

well, i tried to get the best of both worlds...
replumbed the intake of 1 of my pumps, so it can suck from either the sump, or from a tube in the overflow. when the overflow valve is open, is a closed loop, when the sump valve is open, it is a 2nd sump pump.. problem i noticed is that when it is sucking from the overflow as a closed loop, it seems to suck up air... im not sure where its coming from. this of course gets chewed up in the impeller and causes microbubbles..
i think the best option will be to use 2 sump pumps, so if one fails when im not home, there will still be something running, and mod the maxi1200's.
sound like what you guys are thinking?
