I keep reading about PWCs and NOT to top off, well I do about a 33% water change weekly in my 16 Gal bowfront tank, but my water level drops alot due to my cats deciding it is the best watering hole in town ( felines do prefer a moving water source) ... is it really a bad thing to add that inch or so of aged water mid-week???
