DIY Protein Skimmer

Postby mekoi » Wed Jul 05, 2006 12:11 pm

Hi all,

Built my own protein skimmer back in Oct '05 from bits and pieces lying around in my shed. Here is the finished product 8)
Image

This shows the test run and you already see the sticky bubbles coming out of exit pipe
Image

And here is the first collection after running it for 24hrs....yukkkkk :shock:
Image

If you're planing to make one, it should cost you more than $50AUSD, not sure how much is that in pounds :oops:

Any comments bad or good are welcome :)

Hi Jon
I have been thinking about how I could build my own protien skimmer and this one looks good. But being a woman I need more information on how it work's. Could you please explain it to me so I can maybe copy your idea.
Thank you
All The Best

Kim

Sooooo you're a woman, lucky my wife is not around, just kidding :lol: :lol: :lol:

Okay. What happens is the pressure created by the bubbles from the airstones pushing the water/bubbles up to the PET section. It is then tappered to smaller exit pipes pushing only sticky water/bubbles and get discharge, the rest goes to return pipe. You may have to play around the height of the PS to get good result. If you getting water instead of bubbles then you PS is too low, lift it up a little and so forth. Does these make sense :wink:

If you need more info let us know and I'll be glad to help out :)

Hi Kim

send me your email address and I'll send you a diagram of one I built myself (very similar to mekoi's) with bits from a local plumbers merchant.

Better still, if anyone knows how to post a word document, I'll happily send it to them and they can post it on here for everyone!

Cheers

Bob

Kim,
This is the one I've built, from the original article from koi chat.
No photos, but does what it sez on the tin. They're all using the same principle, just slightly different bits...

That's the one Neil.

I spent about half an hour looking for that one in the archives but couldn't find it - then remembered I'd saved the diagram on my hard drive.

Much better with the photos as well though!

Cheers

Not seen one of these Blue Peter'ed before so I want to understand it.

There is no pumping of water - it is just the rising air doing all the work?

And you just sit it in a section of the filter?

Ok. I understand how this works (I use air bubbles to power my undergravel filter in my aquarium) but what is the purpose of this?
What is the gunge being kicked out?

hi john ...the gunge which sticks to the bubbles is pure protein , save the goo and feed your plants with it, excess protein left in the water can lead to water going cloudy or green etc if you can get rid of it so much the better water clarity.
