SPS Turning Purple

Recommended Posts

Setup a frag tank which has been running a couple months.  I added some green slimmer and other greenish corals, which are growing but turning purple.  Any ideas?  I added a zoe and lobo which are keeping their color.

what are some differences between this tank and your display?

I had same issue when I tried green slimer. Slowly turned purple till there was no green whatsoever. Following.

Interestingly, I'm using a prime HD LED light with nearly the same program schedule as my display tank. And, I'm using water from my main display tank. That said I don't think things are functioning the same as the display tank

That is so interesting.  What is the magic variable?  Light intensity/PAR?  Perhaps?

I would hazard a guess that it is different par level.  Have you measured the par at both spots?>  

 

If you are near SW pdx you can borrow my par meter.
