There are three sps frag really pale and they both in the middle of the tank. The lowest one is a cc flaming sunrise 250par ( When lights are out, I can see dark brown zooxanthella on the shaded part of frag but the base has none. The base dose has baby blue color not white).
The tiny bit higher one is a lucky charm frag. It's really pale in color and can't see much zooxanthella on it. 280 par
The one on top is an RR JD. The tip is in kind white color and some part of the base is really pale . 320 par.
Other acros are fine. I also have two yellow acros the have those new growth with out any color. What's might be the problem? Too much light even tho it's only 250-300 par? Too little usable nutrients? Or anything else?
180 gallon
Filte roller
skimmer
no carbon dosing
Po4 was 0.01-0.03 I bumped up not too long ago to 0.1 (potassium phosphate)
No3 was 3-5 raised to 10ppm month ago (potassium nitrate)
13 fish
2 clownfish
1yellow Tang 4in
1 blonde naso 5 in
1 mids blenny
5 anthias (1big 2med 1 small 1 tiny)
1 powder blue 4in
1 swallow tail 3.5 in
1 pyramid butterfly 4 in
Thanks in advance
