i did a google search on this topic and my head started spinning, so thought id ask here and see what you guys say.
My system params first
Alk - 7.5 ( trying to increase it to 8.5 slowly)
Calc - 420 (trying to get to 460
Mag - 1260
Nitrates - 0.75 to 1 ppm
phosphates - 0.03
so almost all my corals are doing fine and are colored up nicely. except two corals. ... the procorals rainbow acro and the wwc SOTR milli.. ( they are in high light (around 600-700 PAR) and medium-high flow)
they have been in the same spot since i put them in the tank, only thing i changed is the location of the mp10 ( really doubt if this would have any affect) and increased the whites from 4.5 hours to 6.5 hours,
the pinks on both the corals are fading .. the pink/red color is still there but they are soo dull it almost looks like white mixed with red pink.
i decreased the whites duration back to 4.5 hours.
now the second question .. .i am under the impression Blue only lighting wont cause bleaching under corals .. is this true or does blues also cause coral bleaching ?
