correct I used a heat gun, after it sat in direct sunlight for a few minutes( temp was 100+). it wasn't easy and no way efficient. I didn't get a chance to try it again last weekend, but will make every effort to this weekend.

The red ring can spin and adjust the hole size. so the water exits through the very bottom of the skimmer! (i guess it minimizes any bubbles going back in the tank... )

CaptiveReefs counter current HO 5ft 8 in Skimmer Design





With this design the skimmer can be run high output 400 gph, I take the water from the sump put it through the skimmer and directly to the tank. Small footprint, but the height is 5ft 8in. Been using this skimmer for 4 years.

This might be a dumb question but here it goes...

How are your making sure the bubbles are small/fine enough? What is doing the bubbling here?

Not a dumb question, the skimmer has a venturi installed in the middle which is driven by an 1,100 gph pump, and a second pump adds water to the skimmer at the top at a rate of 400 gph. When you remove the top you can't see down the tube it's all white with micro-bubbles. The skimmate produced is a wet thick jelly that is dark brown. ( please note I dose the tank on a regular basis with vodka) that really kicks up skimmate production.

Skimmer



Some people had questions on how the skimmer works, the skimmer's main tube is 4 inch pvc, the middle is where I install the 4 inch pvc tee. Here is where I use pvc bushings to reduce down to the size required for a kent venturi valve, which is powered by a 1,100 gph pump.
The same 4 inch pvc tee is also installed above where also bushings are installed to reduce down to allow for a threaded elbow to be installed, this is where I use a 400 gph powerhead to feed water to the skimmer, creating the down flow against the bubbles coming up, (counter current).
And the last 4 inch pvc tee is installed below where a 2 inch pvc elbow is installed pointing up, which connects to a 2 inch pvc pipe, then a 2 inch pvc tee, another 2 inch pvc elbow pointing down, then you can customize the return angle you want.
Looking at the photo you will see the 2 inch pvc elbow at the top, the height of this elbow is very important, because it controls the water height in the 4 inch main tube ( it self levels ). The bottom of the skimmer is closed off with a 4 inch pvc cap, and the top is a 4 inch pvc coupling, and a 4 inch to 3 inch bushing, this allows for a 2 inch tube, which I used a clear acrylic tube to be used to monitor skimmate.
I went with a higher skimmer and at a 4 inch diameter it allows for more flow through the skimmer without bubbles being pulled out into the sump or aquarium. Also note at feeding time you will get some bubbles coming out of the skimmer for a short time, as with other skimmer designs, this happens due to fats,oils,carbohydrates from the foods. Then it returns to normal skimming.
Any other questions please feel free to contact me here.

Thanks, Greg

My contribution is very simplistic compared to the amazing skimmers shown in this thread. I created this Nano skimmer for a 12 gallon desktop build.

I ended up using a Luft air pump, adding a Hydor Evolution Pico pump and crafted a small bubble plate/column (still being tweaked) to quell some of the turbulence. I'm very happy with it's performance
