Good morning all! So I have a deep water Japanese toadstool that has done so well that it has almost tripled in size in just 3 months. Usually very full through the day, but for the last 3 days it has been closing during the day, but when I first get up in the morning I see it open. Then when light comes on, it starts to close again. I have not changed a thing. Parameters as of last night salinity 1.026, temp 78, PH 8.5, alk 8.3, calcium 409, nitrates 24ppm, phosphate .10 ppm. Any idea what might have made it switch like this?
