This is the first instance I noticed the sticky water. Might not be that big of a deal. I'm more concerned with the coral health.
I've got a Bubble Magus Curve 5 in a 90g system. Carbon dosing is minimal at only 6ml spread over three doses daily.
Only mechanical filtration at this point is a Poly Filter. I typically used filter floss as well but just ditched it at the last change a couple of weeks ago.
