Just want to say both my res have settled over last week and are now topped to the brim with absolutely not 1 bubble circulating and no more gurgling or water fountain sound from the res either.

When my aquaero 5 arrives sometime soon hopefully I might try the acrylic loop in the top right like Martin suggested though it looks like it doesnt seal as well because it wasnt designed to go up there because there's no recessed lip for the o ring.

Been playing Crysis 2 in eyefinity and just finished. What an awesome game once you get crossfire working with no flicker! IL2 COD not so good! ;(

Love both my Res Koolance!
