Diy protein skimmer


I plan on building a pvc protein skimmer that is going to be made of 4 inch pvc and convert it to 2 inches for the neck. I am using powerhead to pump the water in the skimmer and I am using a limewood airstone to go against the water flow. Would this work or is there a better design. What other designs are there. I have looked on youtube and the videos do not describe it the best. Can some one tell me if this will work for my 55 gallon tank with sump or is there a better diy design.

I built mine many years ago out of 4" PVC with about 8" of clear acrylic near the top to see the bubbles. It does not use an air stone because it is 5' tall and you would need a very powerful air pump to run it. I built a venturi valve for it but it still uses an air pump to get the air down there. The reaction tube is 1 1/2".
I never had to repair it or clean the body of it. The skimmer efluent runs into a five gallon bucket under it that has a home made shut off switch so if the bucket fills, it shut off the pumps so it does not over flow on the floor. (I'm married)
Before I added the shut off switch it did overflow when 24 local NY urchins all spawned at the same time.

How does the water get out of the skimmer. would the water travel up the tube at an angel like that.

There is a 1" pipe on the other side of the skimmer that goes from the bottom to the top where it returns back into the tank via an algae trough. That is all on the other side, out of the picture.

It does look similar. I added an acrylic tube about 8" long near the top so I can see the bubbles but otherwise it is almost the same. I also built the venturi valve, I don't remember how yours makes bubbles.

that version i just used a Kent venturi valve. for my latest skimmer i used a DIY eductor to provide the air.



the next one will be about the same as the one above, but have two eductors. probably a cone top and a much larger diameter collection tube. it will be for a 300+g tank and will be looking to push at least 1000gph through it.

those simple PVC designed one works extremely well. i had used it for many years. tdwyatt had the original one for a while in his garage. we was going to give it away to somebody. i needed a shorter one, so that is why i went with the eductor driven larger reaction chamber version above.

what adhesive did you use to mate the acrylic to the PVC? did you just use PVC cement? that seemed to work when i tried it, but was wondering about the long term success of it. the next time i had to mate the two materials i used Weld-On 1802 to be safe.

It was many years ago but I think I used regular PVC solvent. The only other option is thickened acrylic solvent, but I think I used PVC solvent. It is thicker.

Is it possible to make an inline protein skimmer from the overflow box to the sump. If I were to make the water flow at a 90 degree angle from the box the skimmer like in the cc shown above and have it flow into the sump. I cannot fit that under the tank but I can fit it behind it. Kinda hard to explain this but if someone understands what I am saying please tell me if this idea would work.

That would work as long as the water exiting the skimmer is at a height above where it enters so it does not empty all at once into the sump. It would also have to be designed like that to maintain the water level at the proper height. Also the water exiting the skimmer can not be in an enclosed pipe to the sump or the water will siphon out. There has to be an air inlet at the top of the bend just where the outlet pipe goes down to the sump.

it could work, but what will you use for air delivery?

it seems some of the newer designed skimmers now have a feed pump that is just a pump, then a recirculating pump for air delivery. if you design a skimmer along those lines than you could do what you want. what size overflow? this will be your limiting factor. the skimmer i just looked at had a Mag 3 feed pump and it was still 10" in diameter. i am not sure how big this skimmer would need to be if it had a to process 600gph or more. 600gph is what a 1" overflow moves.

if you do go this route you will also want to put a safety drain on drain line before the skimmer. it will need to be located just below the highest exit point of the skimmer, either the air delivery hose or the collection tube. that way if something were to get stuck in the skimmer and it starts to fill up, the water will have an escape route besides the skimmer itself. if the skimmer is located completely in the sump, than it does not matter. the safety drain would only be needed if the skimmer is external to the sump.
