i noticed that there are alot of air in the drain pipe. How do I limit air so that more water volume is in the drain?

also, how much lower should the top of the standpipe be from the DT water level? Is an inch ok?
 
Have you looked into a herbie(2 pipes) or beananimal(3 pipes) style drain pipe config? I'm not sure about your current setup. Pics and details would help.

Running a pipe at full siphon will limit air, but you must limit the amount of water the siphon can take.
 
I had to put a hole in the cap and run air tubing into my so I could fine tune the bubble because it was loud on my 45. My impression is that RR tanks with standpipes are adjustable for this though.
 
sorry for lack of picture as I'm at work at the moment...

current setup is a standard AGA reef ready tank with 1" drain 3/4" return. When I look at the bottom of the drain entering the sump (which is a flex pipe at this point) I can see that there is about 25% air in the tube. The drain at no point does it get smaller in diameter. Even the flex pipe has an ID of 1".

That actually is precisely my question, how do I get a full siphon going on the drain?
 
You cannot run a single pipe at full siphon without causing other problems. If you run a single pipe at full siphon it will either take too much water and gulp, or take too little and your tank will overflow. This is what the 2 or 3 pipe designs address.

Oh ok. So I guess by design, my pipes are doing what it's supposed to do.

Also @Nate: the standpipe kits are adjustable...I have a diy standpipe.
 
you can reduce the drain size with a bushing and the end of the drain pipe to backup the water, creating less air

Might be the case. This is why most single standpipes are oversized. They take both air and water at the speed gravity can pull the water down. It's quieter than a full siphon gulping and has less chance of overflowing.

Putting a muffler on the air inlet, keeping the water drop short, and free of sharp bends all help quiet things down.
 
Or as Herbie suggested, drill a hole in the top of the drain and place an air line tube in it. You have to play with getting it in the right spot but it helps to release the trapped air and stop the gurgling sound.
 
The issue isn't with the sound but with the amount of water that is being drained. And it seems like the only way I can increase the amount is by adding a second drain...
 
I have a Maggie muffler for $10... Will solve your problems. No more gurgle at all. Simple to install. I ran a hose from hole in the muffler into stand to limit the air sucking noise.. like a skimmer almost.

thanks for the offer but again the issue is with how much water is being drained and not the noise
