nothing wrong with it. the way i see it is you can never change too much water within reason of course but after a while it seems more like work. 3x30-50% a week is what i do
I do 50% water changes every week...........I do not agree with doing a water change everyday because the biological conditioning needs to settle at times.........This means that the small nitrites eating the ammonia need to multiply.......And constantly ridding of these biological good fighters will defeat the purpose of having an awsome bilogical system growing in the tank.........If you do everyday water changes, then have yourself a good wet-dry filter...........
even a single oscar poop is not a pretty sight........ lol.
