I keep seeing people online not have their tanks water all of the way to the top - is there a reason for this? To me it makes it look empty and you just see the white stains on the glass near the surface before the trim pieces.
I personally do fill my tank up all of the water, I hate the way that water stains look on the tank and they are a huge pain to get rid of.
I leave a little space because it makes it less likely any water will splash out if I have to reach inside and do something, but not much.
Always I can’r stand the space between the trim and the glass if it’s not filled up high enough
Almost to the very top.
