DIY Hofer Gurgle Buster!

I had a post like this one in a different category, but it wouldn't have been found if someone was trying to find a build thread for it in General. So here you are folks! The HGB!

Ok, first you need the following materials:

- 1" PVC Pipe (at LEAST 5" long)

- 1" Endcap

- 1.5" x 1" Bushing

- 1.5" x 1.5" Coupling

- Your desired lenght of Small air tubing. 

- And something to drill holes with :D

(sorry, I couldnt get the coupling and the bushing apart, so they are one piece in the picture @_@)

Step 1: Slide the Air Tubing through the drilled hole in the 1" Endcap.

Step 2: Place your 1" Endcap over /w Air tubing on your 1" PVC with 1/2" x5 evenly spaced drilled holes.

Step 3: Sand the inside of the 1.5" x 1" Bushing so that your 1" PVC pip with drilled holes can slide through with considerable resistance, and place into either end of the 1.5" x 1.5" Coupling.

Step 4: Now slide the 2 pieces together to create your mechanical contraption - The Hofer Gurgle Buster!

Wow.

You just created the device that will bring an end to all noise in the unverse. Good Job! (or at the very least your aqaurium.)

Now that you made it, lets get to know it a bit more!

In this picture, you see the HGB FULLY open. With it like this, it's at MAXIUMUM FLOWAGE!

But, if you think you want it to be a bit more silent, and you think it could sacrifce a bit of its Maxium "Gallons Per Hour," simply slide your Bush and Coupling piece up the PVC pipe to partially block the holes inside.

Heres some pictures of my HGB:

WAZZAM!

Thanks again everyone for reading my guide. 

I hope your tanks become alot less loud. :D

Haha, surprised you haven't :) This thing is DEAD silent the way i have it. It's amazing.

I built a silencer for my skimmer and would think you could build one similar that would work would try taking 3/4 to 1 inch pvc and cut a peice about 2 inches long then put caps on  both sides and drill a hole big enough for your airline to go in one of the caps and drill the other cap and add about 3-4 inches of airline in that

That's more complicated than but just as slender as the "modified durso" but if it's quieter...

It was super easy to set up and I'm quite happy with it.. I'm thinking that the air flow might not be sufficient so that's where the noise is coming from. I'm not 100% sure so I thought I would ask.

I thought about the durso but my corner tank has the built in overflow in the back and honestly I'm severely limited on room, so this model was preferable.

I think I'm going to have to have you explain in person or pics.. I'm confused.. :-)

I know I set them up on Charlie's tank (chastings) and it went from sounding like a toilet to almost 100% silent.

As far as the air line making noise you might have to adjust it up or down to fix that. I assume you made the tube on a slide.

I really need to do this mod... how large at tank or how much flow can that handle with the parts and way you did it?? i have a 75 and just want to make sure that it can handle the flow or does it need to be made bigger?

Nice Mark, take a day for you and your wife. Dont work, just relax.

The mod can handle any size tank. When we did it on Charlie's tank 2 overflows handled his return, which was a reeflo hammerhead! He has a 180 or 210 or something. As seen in the pictures above you can drill holes, but I have found that if you cut squares out with a demel and leave 1/4" tabs between the holes it gives you more flow capabilities. I think these are almost limitless on the amount of flow they can handle. Trust me, I have pushed them. I have the parts and need to do it on my 200, since it is a little noisier than I want. Mark you want to come do it with me?
