I've read Tom Barr's article on non-CO2 methods and worked my way through this sub-forum and have to say I'm very tempted to attempt this method on my new nano. I guess the thing I'm struggling with, which appears crucial to the method, is the lack of water changes.
Whilst this is one of the advantages of this method it goes so against the grain of what I've learnt as an aquarist it's almost like losing my religion. My understanding of this is water changes result in a quick increase in CO2 levels in the tank which plants will try to adapt to in order to exploit it. When that burst is gone they will struggle to adapt back and the algae will move in to fill the gap.

I understand that tap water will have different levels of CO2 than the tank. Does this hold for RO? What about RO sitting in a bucket over night?
I assume the answer is yes as there's nothing in the RO (e.g. fish, soil in substrate, decaying organic matter) producing CO2. In which case I'd be removing CO2 from the tank rather than adding it.
If so, are the levels likely to be so different as to produce algae problems? Especially if I'm not using soil but something like nutrasoil or aquasoil?
Secondly, how do you go about starting it with an active substrate like nutrasoil which I assume, like ADA As, leaches considerable amounts of ammonia into the tank on startup? Surely this requires frequent and large water changes which will set the plants up to depend on higher co2 levels.
