DIY Protein Skimmer V2
« on: August 23, 2006, 05:42:15 AM »
Hi all,

I was really bored today so I did another PS, much better version O0

Matrerials
1 x 700mmL 100mm pipe
1 x 100mm junction to 40mm
1 x 2L coke bottle(must be Zero :D)
1 x 40mm 90deg elbow
1 x 40mm pipe at 160mmL
1 x 40mm pipe lenght to suit your exit area
2 x 40mm ceramic air stones
1 x lenght of air hose to suit
Silicon or pipe solvent

Coke bottle will be cut just under the label


Junction with 50mm exit(water return)


Junction and Coke


Junction and Coke  is a perfect fit


Bubbles exit pipe(40mm) glued to coke then glued to junction


After adding the 100mm pipe, air stones and a small lenght of 50mm pipe for water return you now have the
Protein Skimmer version 2 ;)

Jon,

Do you just stick it in the settling tank and run the airstone?

I think i need one for my pond, proteins are on the surface of the pond.

Lots of foam in the moving bed, ask BB and craig...they say it...

Hi all,

       Dont mean to sound thick but can someone explain to me what the purpose of the 45deg at the junction is
       does it connect to a pump or something?

Steve,

You're not thick at all in my book mate :-* The 45deg is the water return.  Look at the pic to explain how it works ;)

The water enters from the bottom of the 100mm pipe(coz of the bugbbles) and goes out to 45deg pipe. The tiny bubbles are force to go out via waste :)

Hot isnt good. We get air temps here of 40*C! Water is too hot for koi!

The skimmer seems easy, I might make one as well soon, so much foam in the fluid moving bed.

Hi koi38

i picked up all the parts from a local 'tradelink' store
they are a national group i think...
cost : 1m of 100mm pipe           $4.77
50mm to 40mm reducer            $1.45
junction 100mm and 50mm        $5.45
1m of 40mm pipe                      $2.26
90 degree bend for 40mm pipe  $0.90
2l Coke                                   $2.70

so all up-quite cheap !                ($17.62)

how have you attached the airline ?
did you drill a hole into the 90 degree bend up top ?

Larry,

Yes, I did drill a hole on the bend. JUst make sure the hole is a little smaller than the airline you intend to use. This will hold the air stones in place and also will place them in the middle of the 100mm pipe :)

Im trying to make this also and to put it in my breeding/qt tank. I use 110 mm pipes.. my junction is 110mm and 75mm. Is 75mm ok for the water return ??? for waste output I use 32mm . I cutted the 110 mm so its aprox. 10-20mm above the bottom floor of the tank...instead of many air stones I only use 1 giant big one. it  makes small bubbles and move alot of water..i can feel the water flows out the water return pipe and the pet bottle is filled with bubbles...also the airline hose is much bigger  than usual one that people uses in aquariums.my air pump is 28 L/M

Having 75mm as an outlet should be fine. Using 1 or 2 airstones doesn't really matter as long as you have enough air to push the bubbles up and out. I think your 28L/m air pump is sufficient enough. You should have thick foam bubbles coming out not water :)
