I respectfully disagree with this advice. In my experience, there is nothing wrong with doing larger and more frequent water changes as long as the water is properly conditioned and the temperature remains the same. If ammonia is high, why limit to 20% water changes 3x a weeks?
Plants will consume nitrates, but will take up ammonia as a first choice and nitrite as a 2nd choice. Nitrates are the last consumed. There is no harm in adding plants while the tank is cycling.
That's cool
I keep forgetting I'm on the forums again... I'm used to dealing with customers who either do no water changes (and have to be pushed to do a single one) or their idea of a water change is taking all of the water out (because that'll fix everything, right?), not people who genuinely care. I need to revise my advice accordingly! On that note, I've found that very frequent, very large water changes can be more stressful on the fish, because you are adding such different water (as often an ammonia spike would have altered pH as well, which would be different than tap water, in some cases).
I will admit, I was not aware that plants would consume ammonia and nitrite. I'm not huge into the plant world beyond what I've always got!
My personal philosophy is to let cycling tanks be- do your water changes and don't mess with it, since it's such a stressful time for the fish. I was more in the thought process of having one's hands in the tank, messing around with plants in the gravel, was an unnecessary stresser that could wait until the water was more balance.
