I highly recommend the Tunze skimmers. I am running a Nano DOC skimmer on my 33 Gal reef and it is SILENT.

Please tell me how to mod my mod :redface:
Precisely please.

I've shown you mine now you show me yours. :mrgreen:

I may need to buy at least 3 tunze :biggrin: to run my heavy tank, there are 15 fish including 4 angel fish with lots of sps frags.

What does that mean :mrgreen::mrgreen::mrgreen:

Wow you're making this hard. I'm going to give up soon. I can't see exactly what you've done different and recommend a precise change unless I see a picture of your skimmer. Tunze readily makes skimmers for systems up to 2000gal so they most definitely have one that can handle your tank. http://www.tunze.com/149.html?&L=1&C...-infoxunter055

Whatcaneyedo...is the water going in on the right and coming out of the gate valve? Hard to see what's going on there...

No, they both have an air silencer on the air intake. The one that comes on the skimmers are white and red, but these are the replacement ones so you can see how they are made.

Whatcaneyedo, thank you very much for showing your mod picture. But I cannot see very clear how can you mod it with your return pipe. What is the black stuff you are using ? Sorry, I don't have a camera right now to show you mine, I am waiting for this Boxing day coming to get one. Thanks for your time helping me, I hope I can mod mine like yours without buying a new skimmer. I can see from the picture, your surface is completely smooth has no movement of water at all ... that's what I want so badly.

I lost most of my 2006 pictures in a Windows crash... :sad: Otherwise I'd show something better.

First I pushed the grey riser tube right to the bottom and got rid of the annoying sponge. The mod is as follows: 90 degree elbow on top of riser tube, a T off of the 90 degree, gate valve below the T, tie it all together with some short lengths of PVC pipe and add a an additional length to the top of the T. The location of the 90 degree and the T is probably interchangeable. I don't recall exactly why I put them where they were.

Restrict the gate valve to achieve the desired foam hight in the skimmer. Water comes up the grey riser tube, through the 90 degree elbow, into then partially up the T and then down and out the gate valve. Back then if I were to look down through the top of the T I'd see the water level slightly up into the top. Water would exit smoothly out of the bottom with only a trace amount of bubbles but no splashing or gurgling noise. The white speckles in my picture are little calcium tube building worms of some sort.

Now if the water level in your sump is a lot lower than mine was you might still have an issue. I had a 55gal as a sump so I think my skimmer was sitting in 10-12" of water.

I hope this helps.

Whatcaneyedo, I will follow your exact instruction. Instead of spending money on a new skimmer, I can use that money on something else. Thanks a lot for your time, I very appreciate it.
