Can you give a bit more detail regarding the lighting rack... Looks pretty slick..

Because of the depth of the tank, 24" and not knowing what the rock placement would be like I wanted a light that would slide from the back to the front. That way I can push it farther back if I'm working in the tank and can vary the position daily if wanted.

It's all built with a series of aluminum that has been bent to form channels for strength. I mounted heavy duty drawer slides under the middle set of channels and bolted the last set of channels to the slides. The light will then hang from the bottom set.

If this isn't very clear, I do have step by step pictures.

Yea, I kinda got lost in the second paragraph.. lol

Here's the step by step in pictures.

Well, after many months and redos, the tank is ready for a freshwater test. We had to rebuild the stand 6" higher, as there was not enough room to run the plumbing. With a ledge on the front, it should be just perfect for bar height.

Here's the empty tank waiting for water.

Here's the sump and plumbing. Water looks a little discolored because it's a test with our well water. A little bit of iron in the water.

Interesting sump, you have a diagram of it somewhere? Curious to see what the layout is.

Freshwater has been running for a couple of hours now and no leaks. Overflow is quiet as can be. Eheim 1262 pump is completely silent.

Now, here pics of the noise problem. Extremel noisy where the water is entering the sump. There are no leaks in any of the fittings, so I cannot figure out where the air bubbles are coming from. This is the same problem I had with the Durso. Changing the gate valve only raises and lowers the level in the overflow, but does nothing to eliminate the noisy bubbles. I'm sure that once I figure out how to eliminate the turbulance coming from the bottom of the drain, this will be a very quiet system.

Here's the water coming out of the bottom of the drain. (ABS is being used until I figure out how to solve this problem)

Here's the bubbles that have risen to the top. The white hose is the emergency drain. The water level in the overflow is just touching the top of the drain, but no water going down.

To elimiate the noise, Slice little slits in the pipe that is submerged int he sump. this will allow for the air to escape theline before being plunged into the sump.

you will still obviously get air bubbles, but super quiteer.

anyone else have any suggestions?

Here's the drawing of the sump. Quietone pumps were changed to a single Eheim.
