Well said Myka and I agree on smaller tanks especially Nanos I prefer the very large water changes and often do not go much further than that but your right there are a lot of variables from tank sizes to animals and the old answer of just do lots of water changes isn't always the best answer anymore and doesn't always apply universal to each situation
I hope people reading this don't think I'm against water changes I'm actually all for them just not for the sole purpose of exporting nutrients , the benefits of water changes are certainly much more than that
