DIY Protein Skimmer Design

[@nickk6109]

Good video (8 years later!) - just researching for.a skimmer in a gravity fed airlift system for a koi pond. 30,000lph. This has help a load!

Very good explanation of skimmer design and the various methods used to produce bubbles. Thanks for posting.

[@scott98390]

Thanks for the video - I've watched twenty or so videos and none of them tell me what the heck a skimmer is. Now I know.

Tnx Brian for an excellent video. I am trying to get the basics and essentials to what a foam fractionator is. Your video is smack on :-). On question I am pondering on on setting up a pilot for PFAS removal and I have read some litterature on it and watch some YT videos. One of my idea is to use a fine bubble diffuser (EPDM) as you touch on. All the best (independent of it been 11 years since you did the video) /Magnus 😀

Very informative, well done, thank you.

Great video 1st of all I just have a couple of questions. 1st) Your intake and outtake holes are on the same side is that more beneficial than having it on the opposite side? 2nd) If the intake is above the water line (as it looks in the video) won't that chop up the bubbles and prevent them from rising to the collection cup?

Very good video, thanks for sharing...

So clear ,Evan point out the main 2 minutes

love your videos . learning here..... And yeah great idea on cost effective . Saving $for new corals....

[@Admiral_tintin]

Yea great vid! I am still not certain how the water is drawn in and then pushed threw the bottom with out some sort of pump. Do you have this running in your sump now? And can we see it running please!?

[@hotpuppy72]

Not sure I understand your question... air is under pressure so it will go where you put it. I put in a counterflow system.... water enters the top and will exit the bottom because the outlet is at a lower level. Air under pressure enters the bottom and will exit the top. The idea of a very large counterflow skimmer is more contact time resulting in removal of more stuff. Commercial off the shelf units don't allow much contact time.

Thank you for a very no-nonsense explanation. I will also build my own ps. Would one get a similar result by using a larger air stone, wider, yet shorter pipe (so it can fit in sump)?

[@justinsegersten1108]

Good Video, As I was watching it, I was designing my particular system in my head. Came to about the same design as you did based on your info. Couple questions. Does the inside of the skimmer main body need to be accessible for Cleaning? How big is the outlet at the bottom? This is all gravity fed, as you mention at the end, correct? If I don't want to drill my tank, is there a simple way of extending it up in a sealed fashion to create an outlet? I was thinking a simple acrylic box with a hole drilled that is silicon caulked to the black frame? thoughts? Anyways, nice video! I like the use of the whiteboard for explaining!

[@adamsan7494]

Well done Brian. :)

[@limpet76]

Hi Brian Like the video good info for a newcomer like me, half way through you briefly mention a book on Aquaculture maintenance - can you give more info on this book Many thanks

[@nickpotter87]

do skimmers work in fresh water tanks as well?

[@Nickfunny]

thanks for info

[@cichlidselnino6360]

Very helpful vids :)

[@TimothyJanahantr]

i have 30 galonc tank. how length is my skimmer would have to be???

[@P3nur3]

I have a 10 g fowlr setup would you give me an idea for a skimmer? thank you

[@yuvrajnaidu8658]

Hey BRIAN, i want your 2nd part of protein skimmer, please Upload your 2nd Video of protein skimmer.

[@MrWiskin]

Can you do it again but use blue for water? Its just too confusing otherwise!

[@محمدعبدالله-خ6ع8غ]

ممتاز superb

[@TheAtHamptonDotCom]

where do i find the air stones?

[@hierotetsu]

Hi Brian! What's up?! Thank you for the vid, is awesome...:) I saw in the middle of the vid that you recommended some book of aquacultural engeneering for more information. Could you gimme some book references, I'm studing build one for my RAS. Thank you

[@3DEditor]

anyone else hearing the voice of "Peter Griffin"? haha! Great lesson btw!

[@bunnylove831]

THANK YOU!!!!!

Aquatic Systems Engineering by Escobal. Out of print but still findable.

Hi, I am planning to build a tank around 700 gallons (900 gallons in total with fuge/sump). I also plan on using your model since it seems to fit my requirements pretty well. I plan on having my set up possibly Display Tank> Skimmer> Fuge>Sump/return. With this skimmer being a counter flow model, how does the water move through the input and output pipes you drew up? I am in the researching stage and trying to figure out how the water will move from the bottom upwards (if that makes sense) Thank you.

[@hotpuppy72]

The water enters the top, which will be pumped there in the new install. I will run the exit pipe up and use it to establish the water height in the tower. It will then 90 over and go to wherever I want it to be. It's not terribly elegant, but it's efficient. An inexpensive pump in the sump will drive the water.

[@Coasterintheyard]

No, the water is not dense enough to bubble.
