Burnt tips ?

[Z06-Hec]

I managed to burn the very tips of my Birdsnest. Everything else in tank looks fine.
I figured my lights were too strong so i lowered them.
Is that correct?

Post up a picture if you can. Coral growth can look like burnt tips.

Did you just introduce the birds nest? If so, my acclimation routine consists of starting the frag/colony at the bottom of your tank in the sand. I slowly bring the coral to the area where I want it to be. This usually takes a few weeks.

Chemistry always chemistry, what are the values and what are you dosing to maintain those values?

^ As suggested above an image really helps.

Salinity 1.026
PH 8.1
Cal 420
Alk 9.8
Nitrate < 20
Ammonia = 0
phosphates < .001 - Dose lanthium when needed ( Phosphate RX )
temp 76 deg

These are fairly new to my system, I got this entire rack of birdsnest, monti cap and monti digi all grown all over the rack and they are all attached to each other. I upped my light intensity for them and noticed the tips got dark.
There were other branches that broke off the birdsnest that are on rocks at the same level and they are fine.
All other corals, nems, and clams look great.

I just added some cheato to my over flow and trapped it with some light grate to keep it from going into the over flow and in the light.

Here, notice it's not all.

I see a lot of new growth and a few tips with brown/black algae growing on them?
Looks like an other wise healthy colony, I sure hate to mess with that, but you might think about blowing that algae off with a turkey baster, and increasing flow.
Is it possible you there was a chemistry swing that lead to a one time event, are those values staying consistent.
You never see any fish or inverts showing interest or munching on the coral?

Oh wow, your right, its def algae. I just blew it right off.
Yeah its possible a nutrient spike... But i was playing with the lights and set the blue to 100% and white to 80% for a week. I never run them that high so i figured it was that....

I had read on here before that a member had a montipora that had stopped growing and asked what he could do. Someone else wrote that if he would trim the tips back, it would jump start it. My montipora had tips that looked just like yours in the pic. I trimmed mine, and in a short while, it started growing again. I think mine had just a bit of algea growing on some of the tips, so it helped to trim it away. That has been several months back, and my montipora is still growing.
