I've got a few acros in my tank that have begun to STN from the base up recently. It is not all of my acros, most are doing great, even the ones STN'ing have great color and PE.
I am wondering if maybe starvation due to no PO4 could be the issue? Nothing is really "pale" but the only parameter I found that was worrysome was my Po4 which I checked with a hanna ULR checker @ 0, twice.
I dosed a bit of Neophos +0.02ppm and retested an hour later and got a reading of 4 on the hannna (0.012). The next morning it was back down to 0.
I do have a pretty good sized refugium with a very strong light on it. But I am really not sure if low PO4 can cause STN like this (from base up mostly), with good coloration???
Full parameters.
SG - 1.026
Calc - 420
Alk - 7.8-8.0 (checked morning and night to make sure not swinging)
Mag - 1250
Temp - 78-78.5
Nitrate - 10
Po4 - 0 (undetectable)
Thanks all for any advice
