Originally posted by largeload Thank you squid I'm just trying to find out a few things. I've dabbled in this hobby since I was 18 I'm 52 now and I am anxious to learn but I also want to do a little research on this idea.
My interest in denitrators came mostly from the two "fish buddies"/"mentors" that got me started in this hobby...each of them has over twenty years in the hobby and had a lot of "experiance" and advice to offer...One thing that intreguied me was they both used denitrators in various forms...Not being one to jump on the band wagon because someone said "you should have one of these" I also did a lot of research on the "how" and " why" they work...and then took those biological principals and some of the "mechanics" and applied them to my own system.
Could you tell me did you start deniting from a new tank or after it was established?
I put mine in a relatively new tank, after I observed the effects a denitrator had on a larger established system... One "mentor/buddy" owns a LFS and installed a large unit (30' of 6"PVC with 25 cu ft. of bioballs on a large bank of connected tanks, NO3 from 60 to <10 over the course of a couple months)
What size coil are you using?
I use a "box" system, my other buddy has a 4' tube and coil
Are you all fish or reef? What size tank?
I have one of each, the denitrator is in the 125 FOWLR Aggressive.
How long between water changes? What kind of readings are you getting?
...Probably longer than I "should", but I do do regular partial WC...The tank has never gone over 20ppm I thought I had a bad test kit, I bought a new La Motte, thought I made a mistake getting the "low range" kit till I found my readings to be only 3-4 NO3...
Does your coil have bio-balls in it (Isaw a diagram with them in to increase surface area)? Is it prefiltration or post?
It's actually a "box of rocks" designed to increase oxic,sub oxic and anoxic "zones", surface area for anaerobic bacteria to convert NitrAtes to Nitrogen...works on the same principal as the tube and coil systems...different "packaging" It's in the tank and part of the "whole" biological system...
Thats a start if you can answer those questions.
Don't forget that this is only a "part" of a larger "system" that includes LR/LS, a skimmer a refugium with macros and monitored feeding and not a "one peice Panacia" for all your troubles...
Don't get me wrong I just got frustrated trying to get a response like yours. I'm sure those previous posters are trying to help but you can understand my interest Thanks again
Good Luck on your "Quest"
