Hi there,
does anyone have this experience already - how safe is it to hang filters over the rimless tank wall? I have Mr. Aqua 25 G cube (18x18x18), glass thickness about 3/16". I see about 1/32" bow, but I believe it is normal for this size.
Ultimately I am going to add a sump and house all equipment there, mostly for esthetical reasons, but I wonder if I can use over-the wall filter for a while...

Thank you,
Rita
