as soon as i get a dual over flow box. one to the sump one to fuge and another return pump. not sure what size return pump I would need ie: how much flow?

 

You need to match the overflow GPH to the flow of the return pump. This link will give you a good starting point:

I would not use 2 over flow boxes. you really don't want that much flow through the refugium. Have 1 over flow to the sump area and the a small pump to refugium and pvc pipe back to clean water side of sump.

 

I was going to put a 1" ball valve to control flow. The option you suggested will not work for me as Ive already put in the fuge. cant drill tank

 

Looks great

 

I have a sump/refugium with my flow from the display tank going to the sump, to the refugium, and then through the return to my display. The reasoning is that the "treated" water fromthe refugium will take the beneficial elements fron the macro algae back to the display.

If you haven't already done so, you may want to consider having your prefilter feed the sump while moving your skimmer to the sump. Then plumb your flow to the refugium and back to the display.

 

ok this is what i was thinking.............. dual over flow ...1 to sump where skimmer, heater,return pump are. then back to main tank.  

#2  over flow outlet to refugium having its own return to main tank.  they would not  interact with each other meaning sump/refug thus all benefical elements would go directly to main tank

 

I would not do it that way. it will take twice as long to get the water from the refugium over to the skimmer. shoot it all down to the sump and over to the ref then back to the tank would be better than having 2 returns back to the tank. IMO

 

I agree with dave on his comments here! Good advice IMHO.






This is the syphon feed from the display tank nd the skimmer compartment. My flow is from right to left in the 29 gallon long converted to the sump refugium.[/b]

 

This is the refugium which is fed from the skimmed water and the return compartment.
