Ok, you�re right, if the sump and refugium are not on the same level and lights go ,  the main tank can be emptied in matter of minutes. Same level is a must. I did this only by placing some bricks under my refugium to be equal as the sump. The power head is just to return water from the refugium to the sump again. Note that the return water form the refugium is entering the sump where the bioballs were. This power head will determine the flow rate  into the refugium, a bigger ph more flow and the inverse, but it is great that there will NEVER be problems like when using 2 power heads. The pvc pipe will deliver the exact amount of water that the ph returns to the sump, no more no less.

Can you explain agian? What's the pump doing in the refugium?    Bob    -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Sisemore, Chris Sent: Tuesday, October 09, 2001 4:06 PM To: '[EMAIL PROTECTED]' Subject: RE: Sand from Home Depot But then you have to worry about a pump failing & adds more hardware to the system. Also if you are pumping water in & out the flow rates would have to match exactly.   Chris -----Original Message----- From: Andrew Dillard [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 09, 2001 3:04 PM To: [EMAIL PROTECTED] Subject: Re: Sand from Home Depot easier idea is to partition a small section of your glass sump and put a pump in it, this way you dont have to worry about a siphon failing.
