Plenty of flow on the surface in both the DT and sump. I've got no buildup on the surface in either. This theory could make sense though as I removed the blue/white filter floss media and ran no mechanical filtration for a few weeks. That would help explain the sticky water.
As for coral deterioration that started around the same time as the Vibrant dosing and/or the addition of GAC. Those were around the same time December/January.
Gonna leave both out for a while and see how things settle. If I need to go back I'll introduce one at a time and keep a close eye out.
