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.

Wow. Very nice tank & sump. Beautiful design.

Did some experimenting tonight and found if I changed the drain size from 1 1/2" to 1" in the overflow and added a tee to the bottom of the drain, it is quiet as can be. The water level in the back is set just below the top of the emergency drain. The only thing I can hear now is the Eiheim pump and it is very quiet.

So we drained the freshwater and started to put the light rack back together. With any luck I should be starting to put saltwater in it tomorrow night.

Looks Like a nice set up what are you planning with this one mixed reef?
