Keeping purple
 

My purple acros keep turning pink. Any suggestions to get purple back?

I would suggest to get an ICP-OES test done by marinlab to confirm your needs, but this is my hunch.

I dose a kz iodine supplement a few times a week. My blues are staying blue but my purples are pink.

I would still recommend the ICP-OES test. That will take out the guess work.[emoji6]

Im no expert on SPS, but don't they (like many corals) change color based on lighting? Perhaps your specific lighting is making them pink rather then purple?

Again. No expert here; just my 2 cents.

color based on lighting.

I've read blue lighting helps with purple. These corals are sitting right under a blue+, and purple +. Well i changed out the purple + for a geisman 6500k but the corals were pink anyway. I'm not complaining, the growth is great and corals look healthy, just wondering if anyone else has experienced this.

I was right?... Yus!!!!!!! :thumbsup::thumbsup::thumbsup: lol

Have you tried any supplement lighting with LEDs? I know that ReefBrite has some awesome and bright fixtures. Their fully blue lights are freakishly blue! lol Ones under 100 depending on the size and intensity. Might be worth a shot.

My t5 is already retrofitted with two nanobox v3 arrays. I keep it at a 1:1 ratio though. So all channels at the same power.
