No, not really Sip. I suctioned all the small patches off the sand, and did another 2 days of lights out. I will probably spot treat two areas for at least a week, then we will see. It is doing a lot better with everything I have done. The one thing I noticed is that it is definitely affected by lighting! With the Anthias gone, that decreases my bio load, and I don't have to feed plankton anymore, guess that will help. Time for a big water change though, ugh!
