Raising Water Line with Pump???

[peppie]

I have a fuge tank mounted to my DT. The fuge tank is 22'' x 8'' x 22'' high. it is 3'' higher than the DT. I want to use gravity to drain back into the DT.
Will a QuietOne 1200 return pump rated 300gph @ zero head, fill the fuge tank so the water level is 3'' higher than the DT?
My thought was the pump will shut off at 6' (max head). There is 2.2 gal of water the needs to be added above the DT. That is a;ot more water than a 6' x3/4'' tube will hold.
I also would like to mount the pump as close to the bottom of the fuge as possible.
Will this work?

Maybe some pics would help to see what I am trying to do. The pump in the drawing will be a QuietOne 1200 NOT the maxijet.
While your looking pick the design apart. I have thick skin. I want this to work. (two heads are better than one)

Thanks for looking. Any thoughts??????????

Just add a shutoff valve from fuge tank to main tank to adjust levels..

Yes it will fill the tank without any problem, but I would change your drain, if it plugs for any reason, your fuge will overflow and cause lots of problems. Put a nice large drain in the fuge and skip the locline.

Hollister, Not sure why I would need to have a shut off valve. Pulling the water into the fuge and letting gravity dump the water back into the DT after it reaches the 2 1/2'' bulkheads.
Any thought on the pump raising the water level higher?

The quite one 1200, will pump a max head of 6 feet, so it will fill up your fuge without any problems, but I would not do 1/2 inch drains.... to easy to plug.... But it is your tank

Thanks Kgross. I'm Going to have to post this build as Peppie/Kgross
I though about trying to apply some type of back up for that. My first thought was using 3 1/2'' bulkheads one above the other stacked. I need the lock line idea to span the skimmers over flow.
Or I could build a drain style like what is on an Aquaclear HOB power filter. I'm sure you have an idea. In-lighten me

You could just move up to 1 inch bulkheads and stick with 2 of them, with some type of a grate in front of them to keep the everything out.

Now building an open drain would be the best solution since it could not overflow but it is hard to do. I have tried a couple of times on some hang on the back fuges I have built with no luck. What I ended up doing was using 1.25 inch ID acrylic tubing that glued in as the drain, so I had the full 1.25 inch id for water to flow through.

The head in your case is from the top of the display level to the outlet of the fuge. You have no vertical head. Its more of a closed loop.

 

[kgross]

Scott, I can't believe it. I get to call you on this. There will be three inches or so of vertical head, since the fuge is mounted above the display tank. So yes there is a small amount of static head.

I think the 1" bulkheads would be easier on my part. I have room for them. And yes they will have some type of screening on them.
Thanks Kgross.

Build Thread to come soon with Pics. Just cut the acrylic to size today

I saw the 3" but didn't think it was worth a mention, but yeah, a tiny bit of head. I think a pump with 6' max will be OK!

 

[kgross]

Yes there is in this case Scott, the fuge is not sealed, so the "suction" from the drop, does not pull water throught the pump, like in a closed loop. If the top of the fuge was sealed, you would be completely correct.

 

[sjm817]

LOL. I think I edited when you were typing. I thought about it and you are correct!

Either way, I think it will work fine. Id also say ditch the loc line.

 

[kgross]

I just had to call you on it Scott. your one of the few people that are normally correct all the time in their answers..... I'm just glad a few of the other people are not around anymore for some reason....

Sorry to hijack your thread peppie...

No prob guys. It is a very very small price to pay for the expert info I have received.
