Like I said before, I (personally) would not use any so called "artificial" method to reduce nitrates. I value my nitrate too much as a barometer to gauge the general condition of my system. In my mind, it is like the aquarium's speedometer........ if you tamper with the speedometer on your car, how do you know when your breaking the speed limit..... likewise with an aquarium.
And secondly, when you use water changes to remove nitrate, it is nopt just nitrate you are removing...... you are removing a whole lot more contaminants that we don't even test for, as well as replenishing trace elements.
Take two tanks.... tank 1 and tank 2. Now in my mind, if tank 1 is an average size tank with low stock and a good filter, then your nitrates will "naturally" be low, hence you need to do alot less maintenance in general. If you have the same tank, but double the livestock and feeding etc but filters etc are identical, then your nitrates will be higher, hence you will need to do more maintenance. Now if you target nitrates in tank 2 by dosing with sugar, or using a denitrator, you might well end up with less nitrate than you do in tank 1. So, if you are basing your maintenance on your nitrate reading, then does it make sense that you are doing more maintenace on the tank with the lower stocking level? The critical point here is that water changes and other maintenance do alot more than just keep nitrate in check. So how do you gauge what is, and is not enough maintenance if you don't use the usua yard stick to gauge it?
Just as a note, this is meant to be read as much as a query as it is a statement, and is by no means a comment meaning "I think sugar is a stupid idea". I am open to be convinced otherwise, after all it is what this hobby is about....find new and better ways to care for our animals. I just want to know more about this in general......
