Well, that easy-as-pie skimmer is not the prettiest, but certainly the most creative one I've seen. I suppose it would work OK in sump. As is mentioned, I'd be concerned about the long-term status of the holes drilled into the jar. I'd submit that the contact time on this skimmer is not very...

For most aquarium acrylic projects, I would recommend to you Weld-On #4 or MC-Bond. Where you are connecting acrylic with PVC, use Weld-On #40. I try to stay away from Weld-On #16.

I know what you mean. I will have it on my 58g but I like to overskim.

Hey Louey, Is that the Fergy model? If so, how's it working for you? Regards, Art

I found it strange too. I did not prep the tube very well as I machined a groove and used the 40 instead of the 4. THe only thing I can think of is the fumes. Art

It's not on the seam. It's in the tube body. A number of locations.

Just be careful not to cover the tube. I put a little weight on the tube when I bonded it to the box. Of course, I got busy for a day or so. When I returned the tube had crazed in places. Art

Surge devices...Most are difficult to implement (e.g., Carlson, Reverse Carlson, Borneman). They give a nice surge but it may be too much close to the device. Additionally, they add noise and bubbles. Wave2k gives a nice motion. Read the posts on RC. IMO, the stream is the most dependable...

Tunze stream. Best movement for SPS to date.

Fergy, I polished the edges and did the Weld-on 40 gluing yesterday. I am extremely happy of how the polished edges look. I followed your previous comments and used 150, 240, 320, 600, 1200, 1500, 1800, 2400 and then buffed with the wheel. It was a lot of work (2+ hours) but the result is...

I'm going to take a shot at building an algae turf scrubber, a Nilsen reactor, and a couple of skimmers. That's all I can think of right now but I'm sure I'll dream up something else.

Louey, It's a float valve. It is really overkill in my opinion. If CO2 accumulates too much in the reactor tube, it causes the water level to drop. If the water level drops beyond a certain point, the float valve opens and vents the excess CO2. This vent is only useful in the case that the...

Fergy, You asked us to post our modifications for the class. I'm doing so. I've added an O-ring as per the other thread. In addition, I've added a stainless steel pressure guage and a CO2 vent system to the top. Lastly, I've added water and CO2 flowmeters. I'll post pictures once I'm...

That's how it works. I also add some weight to the pin arm before I start cutting. The added weight causes the arm to tilt slightly downward applying pressure onto the template. The channel depth on the template can be deep and really doesn't have an impact on what you cut. That is...

Hal, Thanks. The image you are seeing is a little misleading as I have the roundover bit in there. The round nose bit I'm using for the O-ring would only slightly be visible above the table. I then align the pin with the router bit. Then I turn the screw to raise it. Put the piece in and...
