Coil Denitrator?

[Delphinus]

Doesn't the Fluval itself have a powerhead? So a valve on the input or output might work? That's mostly why I was asking the question though, just curious how the flow was handled, if it was the built-in powerhead or whether that just sits idle and an external powerhead is used.

Ok, Tony. Gotcha. My understanding is that you never want to restrict the input of a powerhead, but that you can restrict the output. As such, I guess a ball valve on the output INSIDE the Fluval would be the only way I can imagine? I don't know! Interesting question.

Albert had one set up at Gold's a while ago, not sure if it's still there. Very simple design. It just used 1/4" line coiled around 3-4" ABS pipe as many times as would fit. Fed by a small pump and controlled by a valve.

If you are reading Albert, tell us how well your design works.

Yes someone please post results. and materials w/instructions

How would one of these work on a system without a sump??

I do need a de nitrate of some sort as mine are always @ 40 - 100 thats with 20% h20 changes every 2 - 4 days.

Don't forget, for a drip rate you can always use irrigation drippers sold at Home Depot or Rona to name just two sources. You can get 1/2 gallon per hour, 1 Gph or 2 Gph drippers. I used them on a homemade Ca reactor and just made sure I changed them often. They're cheap so no big deal.

PS I would think a Fluvel would be great as a housing for the coiled lines, input from the tank/sump and output into the sump at a controlled rate. Coils are supposed to be kept in the dark if I remember right so the fluvel would work well.

I dont know about the light thing but it's true the 403 is a dark smoked grey.

Yes please i would like to know too if the tank has nosump how would you get your Fluval to a controlled drip rate without pressurizing the unit also can this coil Denitrator be combined with Sulphur Denitrator? Just wondering?
