Coral health question

[djray77]

Im not sure if this coral is annoyed or not can someone tell me if it's OK or something wrong. This is placed at the top of the tank with a T5 Hybrid fixture with Xr15's running the AB+ program at 50%.

This is the same coral in another tank I have and the coral is completely different. This is under 2 black box LED on 100% blues and 50% whites.

It's very hard to see the color difference with the blues.

How long has it been in the new tank? Water parameters of that tank?

Its been in there for at least 2 months sorry I'm not more accurate on that. I fragged a piece for the new tank and left the donor in the original tank and thats been grower better and has a bright green color. Whereas in the new tank it's white, dull green and brown at the base and doesn't seem to be growing much. I figured the T5 Hybrid was the way to go but I have much better luck with the cheap black boxes. my par at the top hovers around 250-300. Its strange because I thought the white is to much light and the brown is not enough?

SG:1.026

0.049 phosphate
0 nitrate

Okay, I have better luck with black boxes too.

Depending on light intensity/spectrum and lack of nutrients, it can loose color.

Having "0" N03 and very low P04 can definitely cause paling.

Couple things can be done:

Reduce light intensity and or photoperiod during this time.
Or
Lower the acro on your rock work.

Feed more.

Take your skimmer off line or just during the day.

Reduce water changes to biweekly.

Above to "dirty" up your water.

Dose sodium nitrate or potassium nitrate to raise N03 to 5-10ppm.

Dose phosphate to raise P04 to .02 (your phosphates are fine where they are)

Raise N03 first to Target, then P04.

It's crazy cause I took out carbon and gfo a few weeks ago, haven't done a water change since 7/24 and I'm feeding pellets and brine/mysis and still very low no3/po4. And they say canisters are nitrate factories lol! I'll take the skimmer offline and see what happens? Should I unplug it for a few days you think and test again?

I actually just bought a new salifert nitrate kit because I thought my red sea one was wrong.

Looks good to me

Retest to verify N03.
