Glad to see the DIY Coil Denitrator thread is still going strong after so many years. But I do not want to tag my specifc question on top of that thread. I could really use some expert advice on building one of these for my 210 gallon FO heavily stocked set-up. I have read all pages of the existing thread and read about numerous set-ups for various size tanks and could use some help for my 210. Hope someone can help.
I am pretty sure I will go with a 4" PVC pipe and kind of like the idea and ease of wrapping non-translucent tubing on the outside of the PVC & feeding it inside to the bio-balls (however I am not committed to this design if anyone does not think it is a good idea). I will be utilizing a small external adjustable flow pump (79GPH). Here's what I could use some help with:
1) What height should the PVC be (assuming 4" diameter pipe)?
2) I have read about a couple of different size diameter tubing. Which size is recommended for this setup 3/8" 1/4" etc. Please provide OD & ID.
3) How many feet of the above tubing will be required? or if coiling is necessary, how many coils of what length? If multiple coils, can they be coiled on top of each other in one continous feed as oppose to multiple coils with multiple inputs?
4) Based on a 210g tank, am I better off just building two units or will one do the trick for this size tank?
Anything else you can share that might be helpful or good to know. Thanks in advance for your help.
