Hi!
I changed might light to a Kessil AP9X, and i ran the acclimation program. Just after the program was done i noticed a couple of corals got some brown tips, and in fact one Arcropora died on me. It lost it's tissue and i'm not sure there was anything i could do. I was really stressed during this time so i had no time to check for PAR or anything. I was hoping an acclimation program for two weeks would be ok. Silly me!
But, i still have three tiny frags which i think is Acropora Valida (purple) and they have some brown tips. A week ago i measured the PAR and it turned out to be like 600-800 PAR. I adjusted it to around 400-600 PAR about where they are located. Another Acro is located on a bit farther to the left and seems to be ok. So this browning of tips i recon is from the new lights? I have made a new program, and i wonder if you guys think i should max the purple bar to max for all points? As a side note i can tell you that this light will fry anything. The acro that "melted" got 800 PAR.
Another noob question: if i up the purple to max, will the PAR or maybe PUR increase? Maybe both? Lets say i'm happy with the intensity and just increase the purple color? I mean i wont't touch the intensity bar. Because i think purple is good for corals?
I think the current setting is quiet good, but if the purple color is more beneficial then i will increase it.
And i kept the red and green a bit higher just to make the light look better. I think the red promotes algae.....but does it hurt anything to keep it that level? I have attached a picture of my current program. Any input is appreciated! Thank you, and have a great weekend! Oh, and tomorrow i will measure PAR again because it changed the position slightly again.
