Okay - I am having a little issue - the other night I walked in the room and my tank was all milky cloudy. I ran downstairs hit the switch and did a 50 gallon wc. Tested all my parameters and all was in good range. Scratch my head- turn and see that my feather caulerpa went asexual- literally melted in the tank and disappeared! so I pulled the dead and dying out - and now my Duncans are closed, my acans are closed My anemone looks small. I got some algae bloom in my DT, Checked my parameters tonight and all good still??
