Seems more water would be processed with a longer length
NO NO NO NO

wrong direction!!!!

the coil has to be the correct size, larger diameter = longer coil, and its a heavy curve you double the diameter you almost tripple the length, dont experiment until you understand that, the results are BAD!!!, not trying to scare you away from building a coil denitrator, just be careful

next thing, of all the water that goes into the coil ALL of the nitrates are removed (assume its working)

so how high of a bio load are you expecting,
a 2 coil unit using .170ID tubing 50' long will process aprox 8gph, you can do the math you do know that its not the same as a 192 gallon water change each day, as itll reduce the nitrate but itll mix and its kinda the same as frequent small changes but its going on 24/7, think you will need more processing power add more coils. now if its a breeding type of setup or another very high bio load setup, you can up the diameter and the length to process more but you add some $$ and up the process rate to way high.
