Hi all,
I'm stuck. I've had a problem with my green palys closing up - they haven't really been open for weeks now. All other corals, including yellow colonials, are fine. But the palys and some random zoas are curled up and closed.
90 Gal - Parameters:
pH: 8.1
Ca: 400
dKH: 8
Mg: 1200
temp 78
Ammonia, Nitrate, Nitrite, Phosphate all 0
I also run carbon 24/7.
Iodine is 0 (last thought of what could be going on). Been attempting to dose Lugols (approx 2-3 drops a day for fear of overdosing). Testing with SeaChem (I know, but...) test kit, still reading a 0. I'm also running the comparison test at the same time with the kit, and that is coming out at normal levels, so I know I'm not testing wrong.
My question is twofold. Should I continue to dose the Lugols and test - slowly but surely? Put a higher dose to try to raise levels? And would that likely help with the coral issue?
Second: would carbon strip iodine out of the water? I know the polyps use it and can deplete, but I'm confused why I'm adding and not seeing a level increase.
Thanks in advance.
