DIY Monster Beckett- Graphic Intensive!

Ryan- I use O-rings that I counter-sink in to grooves.

Niko- That varies- about 24" or so though. Much taller and you can't get your hand in it to clean, so it needs to be made in two parts, with another flange.

Hi Zeph,

Here is my DIY skimmer during the run-in test. I have no space in my sump for the submersible pump, so I test the Skimmer in 100 l Test Tank.
The picture shows after running in 15 minutes. Why the foam stop raise up after running in 25 minutes?

New skimmers don't perform well until the acrylic has been washed clean, and coated by organics.

Give it a week or two before you start to worry about it. It looks reasonable to me so far.

Zeph, My current 24" model is starting to get algae and tiny specs of coraline growing in the reaction chamber... is this a problem? I was thinking of blocking the light it gets with some plastic. what do you think?
 
I get algae in mine too- I don't worry about it much.

Blocking it with black plastic would not hurt at all, and might help too.

Zeph does yours run with a gate valve to adjust the height in the skimmer or do you have the pipe come up and elbow back down at the height you want? Which do you like more?
 
A gate valve makes it easier to adjust. If your skimmer design has a slow flow rate that you never adjust, then the U pipe is fine really.

Zeph and others,
would you mind taking a look at the attached pdf and see if you see any flaws in the design. Or at least other ways of doing things. I was going with a 3" down tube and won't have the pocket like your ultra had between the down and the coax portion. I appreciate your input and your designs absolutly rock :thumbsup:

I'd be concerned about the 3" tube- It tends to collect air and air-lock unless you drive it with a big pump. You may need to restrict the bottom of the tube down to 1" or so, to prevent that.

Looks good though-

Add in some Novaqua or other foaming agent, and watch it empty gallons of water on the floor. :)

You could try soaking in a light vinegar/water bath, but I just let them run on the system. My latest big skimmer I put on my tank was foaming in a few hours. The previous time, it took days. It all depends on the type of acrylic used, and how it was manufactured I suspect. (They were both cast construction, similar designs).

bl, you did a great job on your skimmer! I do want to know more about your DIY nozzel. what do you mean by
"I mounted plastic toy ball with plastic strip and in PVC Sock Dia. 1" I Mounted shaft with cone usually use for fountain nozzle"?

This Injector is the same injector I use for the skimmer.

Finally, I change the plastic toy ball with bioball.
I have no more fountain nozzle, so I cut the Injector into 2 pieces the last DIY Injector in hand because I didn't use anymore.

I hope those pictures can help.

Downdraft tube

Downdraft tube

Does the downdraft tube have to be higher than the entire riser tube? In my design, the downdraft tube was only half as high as the riser and I have water shooting out the air hole. The beckett was not sealed, so I plan to seal it and increase the height of the downdraft tube to almost the height of the riser but not higher than the colletion cup. Does it need to be higher than the collection cup, or is the problem that the beckett injector was not sealed? Anyone, please advise. Thanks

The Beckett chamber has to be sealed.

Higher than the water level helps- After I started doing that, everyone else followed. :)

Zeph,
I have been planning on doing a DIY skimmer and just finished reading this thread. Beautiful work! I admire the patience of a craftsman.

My setup has a feature I desire to exploit, if possible. My upstairs tank flows to a basement sump. The net result is from overflow to bottom of sump is about 10 feet of potential head.

I could therefore deliver up to 10 feet minus height of Beckett injector worth of pressure to the injector without using an additional pump. Volume would be a non-issue.

I can't find any data on Beckett 1408 pressure ratings. Do have any data or opinions on this idea?

Cheers!
 
10' might be enough to make it work, but I suspect that it would not work as well as an Iwaki pump.

Best thing to do is to get a Beckett, make a chamber for it and simply try it in to your sump.

A long time ago I took made a water flow/air flow curve for the Beckett, but I've never tried to measure pressure in to the Beckett vs. water flow/air-flow. That would be a good test to run, I'll add it to my list of things to do. :)
