2x EDUCTORS & NO MORE POWERHEADS!! - Page 6

Jester · #**126** 05/04/2007, 01:28 PM

I was able to find everything except the reducing coupler(they were sold out)... I am going to go to another Lowes and look later... or home depot, now that I know what and where to look... I didnt realize how big these things are... I hope they are not too big for my 25 gallon tank... I may only use one...

Does anyone know if there is a way to make a smaller nano-version of this design for smaller tanks..?? If not, I may tackle the challenge after I build a original one first...

I built two of them during my lunch hour, way better than the lockline nozzles that had been there,
3600 gph on 4 outlets, if I close the other two down at all they start pulling air from the top of the water, way better and random flow, corals are doing great

One should be just fine in a 25g tank. I have 2 in a 90g

What return pump are you using I?

Smaller versions are possible but will most likely need higher pressure pumps to perform as good.

I am using a MAG7 return pump and I have it split with a SCWD... I was planning on building one for each outlet of the SCWD... does this sound ok..??

I have all the parts except the reducer coupler... I am going to a plumbing store tomorrow to see if they have it there... also, where do you use the plain abs piping at..?? The parts list calls for a 1" piece of 1 1/2" ABS piping, but I didn't see it in all the assembly pictures... Thanks again everyone..

A Mag 7 on a SCWD should be plenty for a 25g tank

I'm just not sure if the eductors are gonna take up too much space in a tank that size.

Here is a better set of instructions:

You are looking for Step #3

Good Luck!

bbeck4x4 · #**132** 05/05/2007, 09:28 AM

the tank is partly sps with softies as well, one eductor in each back corner, moved plenty of sand around at first, now it has settled down.

I would recommend these to anyone.

Just found the answer for all of you with the Lockline blues

Attach a threaded adapter to one end and attach the Eductor to that!

raddogz · #**135** 05/08/2007, 02:02 PM

cool beans

Thanks!

marino420td · #**136** 05/08/2007, 02:14 PM

I just received those same adapters (only in black) and used them to attach to locline. It works great and they are fully adjustable. Now I just have to make several more for my CL.

ivgonmad · #**137** 05/10/2007, 01:04 AM

I wish somebody had a flow meter I could borrow... It would help me a lot trying to figure out what the ideal pressure is for these eductors.

Where did you get those black adapters from?

Worldwithin · #**139** 05/10/2007, 01:04 PM

I just installed a pair of these on my return and, granted I didn't have the same barbed connecter that was listed, I am not seeing much improvment on the output. I will try to locate the barbed part at a local hardware store to see if that changes anything. Sad part is, there is no Lowes local to me at all. Closest one is at least 30 miles from where I live. I do have Home Depot's and OSH's all over, but no Lowes.

*sigh*

raddogz · #**140** 05/10/2007, 01:25 PM

Try the OSH for the barb as I know that they sell it.

Worldwithin · #**141** 05/10/2007, 01:38 PM

All the barbs at the OSHs around be only sell a 1/2 to 1/2, no 3/4 to 1/2. Granted I may not be looking in the right place for them too.

raddogz · #**142** 05/10/2007, 03:09 PM

3/4" hose barb SSF Osh

The barb is normally located in the sprinkler section, they should have it anywhere they have irrigation supplies, good luck

The link I provided lets you choose between black, orange, and grey.

ivgonmad · #**145** 05/12/2007, 01:57 PM

This is a good source for some if not all of the needed parts

One question: do I need to increase the pvc parts to the next dimension for a 1.5 inch return pvc pipe line?

I understand what you said for the 1 inch, but now I found out that I need to use 1.5 inch all around with the dart.

ivgonmad · #**147** 05/16/2007, 12:00 AM

ivgonmad · #**148** 05/16/2007, 12:00 AM

No, you dont, you only have to find an adaptor that will connect the 3/4" thread on the hose barb adapter to your 1 1/2" return line.

I'm sure there are 3/4" to 1 1/2" reducer couplings or plugs that will do that job.

Psionicdragon · #**149** 05/16/2007, 10:02 AM

oh nice. I thought you have to increase the size of the Ivgonmad's educator because of the increase size in return pipe.

this makes it a lot easier.

Thanks,

Ivgon

DriftRtist · #**150** 05/16/2007, 07:25 PM

Hey, I had a question for you guys. I have already built the educator but I noticed that I can't have a siphon break hole in my return line. So is the only option to have it on a 90 fitting close to the surface? If this is the case, won't it shoot water everywhere when you first turn it on?
