DIY Deltec update (pic)

[kentrob11]

Well, I finally got around to getting a twist lock flange mounted and actually did a test run with salt water and I gotta say this thing looks really promissing. A while back several people mentioned the possibility of using a 2400 on it instead of the 1500 and while I think that wouldn't be a bad idea, I think it's looking great so far with the 1500...I can tell this thing is going to need a few days of break in time but we'll see how it looks in a few days...

Looking good.

 

[Letmegrow]

Nice.

 

[DrBDC]

How many gallon tank do you think that will be good for?

 

[kentrob11]

well, the pump is comparable to the Sedra 3500 so it's comparable to the ER RC100 rated at 100 gallons. I would say that this skimmer would do a solid job of skimming a 100 gallon tank....

What kind of fittings are those? They look like some kind of union connectors/bulkheads.

 

[Letmegrow]

Compression fittings.

 

[chadfarmer]

kent that is a 6 inch tube not a 5 inch tube


i would say rated for about 125 gallons

 

[ARLO]

Pretty awesome looking..

kent remember there will be back pressure on the pump as you are flowing water into the skimmer

 

[dela]

You mean like Uniseals? If not, then where do you get them?

 

[kentrob11]

OK...catch up time:

The main connections on the body are uniseals with modified sch80 unions. The connection on the top is a CNC milled twist lock...

Chad- I was thinking the same thing but didn't want to over-estimate. As far as back pressure goes, The water level inside the body is what causes back pressure due to gravity- I filled the skimmer to the height that I believed the level would be at when water is being fed to it so I think what I'm seeing is a pretty accurate demonstration of how it will perform when in operation...BTW, Sanjay got my address today and is sending the H@S Eheim tomorrow

Here's pics of the skimmer for those that missed the earlier threads:

 

[chadfarmer]

let me know

 

[kentrob11]

Will do man- Sanjay is doing some cool stuff with his too- He's machining plates that are about 1/2" thick and flat on one side and contoured to mount to the side of the 12" tube. That way he can use bulkheads to mount the pumps to the skimmer body instead of uniseals...should be neat

I was just wondering how you modified the union? Do you have an pictures of the union so I can see how it was changed? Thanks

 

[kentrob11]

I took the threaded half of the union and cut the pipe slip fitting portion off with a band saw. Then I wet sanded it down to a smooth, flat finish flush with the bottom of the threads. At that point, you still have about 1/4" of gluable surface area as well as the flat surface on the inside that the pipe butts up against when you push the pipe in. When doing it this way you need to be sure you have a smooth, perfect right angle cut on the pipe that you are gluing in so that you get a solid bond when gluing it up.

 

[shadofax69]

That for the help

 

[shadofax69]

I had another question. What type of venturi valve are you using. I just got my GenX 1500 today and the verturi they supply cannot be used for a recirculation type skimmer. Did you make that venturi or purchase it.

Thanks,

 

[kentrob11]

I made it- Before you go doing anything, WHat size tubing are you using and how tall will the skimmer be? The reason I ask is that After running mine for a few days I've discovered that this pump is a bit too small for this skimmer. I'm going to replace it with a 2400....
