Nice Work! What was the cost involved for everything and approximately how much time did it take you?

it took me about 2 hours in total..
the cost was under 50.00 bucks.
minus the media about 30.00 bucks.
the valves and the bacteria media were the most expensive.
thanks
Neal

Thumbs up

Finally got my Coil DeNitrator up and running. No results yet, as it has been on the tank for an hour.

Drip rate is 1 - 2 / sec. and drips directly into the tank above the surface skimmer, so basically is drips into the surface skimmer, then goes throught filters and back out the other side. ..

will post Nitrate levals weekly to see how they drop. Currently , using Aquarium pharmasuticals tester,

Nitrate is @ 160 PPM as of 03/04/07

Just tested again after water change and 3 hours of denitrator (not having an effect yet i know...)

looks to be @ 80 ppm mg/L

hard to tell with these test kits.

Bumping this old thread back to the front.

For those that tried the coil denitrator, how have your results been in the timeframe up until now?

Default Design question?

4 - 1/4 inch quick connect union
1 - 1/4 inch shut off valve
1 - 1/4 inch quick connect valve
material for growing bacteria - (bio balls and ceramic rings)
1 - 4 foot piece of 1.5 inch pvc
duct tape
pvc glue
teflon tape.
How about using wider then 3” Black PVC ? say 5” pipe?
Then we can roll more tubing say 30% more, and leave it on the smaller diameter 1.5" PVC pipe. Now you don’t have to remove the inner 1.5"PVC pipe, just insert it together with air tubing inside the wider then 3” PVC and drop the bio balls or coral rubble inside.
So this is pretty much the same thing except now we have more uniform air tubing distribution with possibility of longer water travel within same hight unit just wider and one does not need a second person to unload the air tubing.
Maybe if cost is still low this can be done in even shorter but wider unit that will fit under the aquarium stand.
What do you think guys?
