Coiled Denitrator DIY

[JohnO]

BL,

Is the CD going to be sitting in the Sump? If so how about this for an idea :-)

Remember the old under gravel filters? The ones with the plastic plate and the riser tubes? You would connect an air pump to the riser tube and the bubbles rising up the tube would move the water.

If you DC was sitting in the sump you could put a tee piece in the output pipe ( it would have to be a vertical pipe ) and feed air into the tee. I would bubble up and suck water slowly through the DC.

I would not want to be inside your brain JohnO! You are just too creative!

Actually, it is too big to fit in the sump.
But I got the coils in!!!

Do you think there would be enough flow or pressure to be able to push through 40 feet of tubing and the actual cylinder. I have heard from the few people left that swear by UGF is that they do have a decent flow rate. I personally am skeptical.

SF,

I'm skeptical too, I was just throwing in another idea, that's all :-)

I saw you got the coils in :-) The patience of an Angel :-)

Now if I sent you a piece of pipe and some tubing.......................................

Sadly, I needed to use a good bit of glue....I hope that is OK....

[JohnO]

It should be just fine :-)

John I think you need to wrestle your coil back from the dog and try that out. That's an interesting idea.

Thanks Matt,
I've been thnking about air driven water circulation for a while. The idea can from the Aquatics Engineers website diagram shown here

That's wild you used that diagram, that is what I was thinking about as an example too. Long thread in product review board about that thing.
