HELP my tank is now cycleing with 4lbs of live rock and 10lbs of old rock that someone was giving away that they used like live rock, it also has 20 lbs or about 2.5-3'' os live sand. i mad the sump myself and i used a pwerhead for my water return. should i get a diff water return pump? and what do i use and where do i get one??? i was going to use bio filtration but since i have so much rock and sand i found out i need carbon or protien skimmer so ill be putting carbon in the sump. should it trickle over the carbon or does that matter?

The check valve is there to make priming the overflow easier. Without it, you'd pretty much have to submerge the entire overflow rig in water to fill the top loop. Instead, with the check valve, you can just suck the water out of the top loop to fill it with water.kimowen04;3252895; said:
Chances are you have a hole, or your check valve is dead. Check valves tend to die after you've sucked water through them a few times. Try replacing it, but if that doesn't help you will have to check your piping for air leaks. Even a pin hole will stop the DIY overflow from functioning.kimowen04;3252895; said:
