You normally drip depending on your evaporation rate. It varies from tank to tank. It also depends on how what your calcium levels are at and what you want them to be at and adjust accordingly to those.

ok. tonight was SUPPOSED to be a good night but when the sump was full and the tank was at the right level, we started the syphon on the drains and the return pump and it ran good for about 2 min. then we heard somthing coming from the sump, when we got there, we found this.
 the return pump is sucking the sump dry. its like the water isnt making it around the baffles quick enough.....we had to restrict the flow on the pump to almost nill to keep it somewhat full.... what the hell did i do wrong??? here is another shot. a little closer  PLEASE help me ASAP

Can't you just add more water? Won't that work?

did you get a pump that will somewhat match your bulkhead rating?

How are you drains plumbed? I only see 1 drain pipe going back into your sump?

 Did you join the 2 1" pipes coming from the drains Did you use 1" pipe after join If so the 1" pipe won't be able to handle the flow of 2 1" pipes If the tank overflows when you open up the flow on your return pump the drains are being overwhelmed, 2 1" drains should be able to handle that volume What are the linear dimentions of your overflow? From Reef Central Mag 18 at 4' head with 2 90's = Gallons per Hour = 1115 Drain and Overflow sizes are calculated as Recommended minimum drain pipe diameter = 1.38 inches Recommended minimum linear overflow size = 17 inches HTH Dan

Looking at the sump, I noticed couple of things.
1.Try having the overflow pipe come even with the water, ti minamize the bubbles in the sump. 2. I dont think you have enough water in the sump to go to the tank. What im saying is you tank will drain the waterthur the overflow. once gravity takes over. If you have any of the piping blocked off open the lines to the sump wide open. What are the overflows are they 1" pvc or 1.5 " rule of thumb is 1" pvc will handle 750-1000gph 1.5 " can handle1250 to 1500. But IME/IMO add more water to equal out the sump... Now saying that on my tank i have a 3MD with 1.25 PVC and it works good and that is pumping around 500 gph. IMO
