I am going to be setting up a fuge this next week...just making sure I am going to get everything right.
I have a 55 gal...I was thinking of getting a 20 gal fuge.
A pump question?
I need one pump to pump from the fuge to the display...and then another to pump from the display to the fuge...right?
Never used a pump so just making sure I understand them.a
is 650 an hour okay for water flow?
I planned on getting LS, LR, and of course the other essentials...what type of lighting do you recommend...is the bulb that comes with a stand hood good...or do they require more light then this?
Thanks!

No!
Only use a pump to move water uphill. Always use gravity to get water downhill. If you don't follow this basic rule you will evertually have a flood or worse.

It just seems as though water would be going out of the fuge faster then it was coming in.
That might just be my little brain not grasping the concept.
Thanks for the advice so I don't have a flood!

Sorry to keep asking I just want to make sure this is right...
So how can I calculate how much flow will come out of my tank. I dont have an overflow in my tank I was just thinking of attaching a 3/4 tubing to my tank....do the whole suck the water throw and then let it go into the fuge....then have the pump....pump it back up...how do I dont how large of a tank I should get for this then?

let me clarify. I just recently set up a fuge. I have a 20g, with a 180 pump going up to it. Then a syphon going out. Its hard explain without seeing it, but as long as the syphon tube is larger than the incoming, the syphon will match it flow,(the syphon cannot suck more than the incoming, or else it would break the suction). As for as a flood, the only way to stop it would be to drill your fuge. if the power goes out, your suction will stop, then the power comes back on and theres nothing to restart the suction, you will flood. matt

Don't ever use a siphon. You need an overflow of some type. A siphon will stop during an overflow but it will not start up again after power comes back on. You will never be able to reliably match a siphon and pump speed.
I prefer built-in overflows. If you don't already have thet then your only choice is a hang-on overflow.
