I have always heard this, but I have to admit I have never seen an
explanation. I understand the ammonia toxicity, and the effects on
nitrifying bacteria (which don't matter in a planted tank anyway), but I
don't understand why the fish should care until it becomes so acidic or
caustic that it is causing burns or tissue damage.
