been running lunar mode since I got them few months ago, what I have noticed is output has decreased drastically from running at the 30% min to running 80% now and it still outputs less .. I know this cause at 60% or above it would create a wave that would push over the front of the tank, place on back facing front .. , I have cleaned them out with no noticeable difference.. but was fairly clean .. not sure what I can do.. still work really well just the output seems less then my return pump now 
maybe someone has an idea? or maybe someone from maxspect some input on this ?
