Denitrification coil

Quote: Did I read that correctly? 5'-0" of sand in a 3/4" pipe?


That is correct, it goes through very slow like a drop a second. It's a tiny table fountain pump and there is a valve on it that slows it down even though even at full flow it would barely come out as a stream. I built it in 2 sections like this because I can either remove the tube part or the sand part while the other part can still work. So if the sand clogs, I can remove it and put in new sand, then in a month or so the sand will cycle. It's just an experiment and I doubt it will revolutionize de nitrification as these things have been around a long time and always prove unreliable and a little irratical

Hey Paul this is off topic but do you still have that white or black worm cheeper you build.

 

[Paul B]

I have a white and black brine shrimp hatchery and shell seperator that I use every day but my worm keeper is white

Hi fizzy how does it work?? Nice job

 

[fizzy]

this is a simple design, there are 2 inlets, 1 for water coming out and 1 for water going in, the water that goes in is the bigger fitting on top, this is conected to the coil of airline tube that is wrapped around on the inside where the bacteria lives then the water passes over some plastic media and then come out via the small airline fitting very slowly.
