Burnt

[Gordonm]

Now I know what a burned coral looks like. Not sure what kind of monti it is but when moving some things around I noticed the one side was black. It's a nice reddish encrusting one or at least was all around, dang it. The others all seem fine though. Anyway it's now off to the side and my intensity lowered a notch. Wish i had a par meter!

Do you have a picture? What lights are you running?

 

[Deep]

Is this the only coral affected? I would not make changes to lights for one coral. Can you move it ?

 

[Gordonm]

It's a G5 radion and i moved it just off to the side a bit. I'm at 43 percent intensity in a 40 breeder. Was thinking of lowering it back to 42 intensity.

 

[Gordonm]

Only the one affected yes

BRS did a video on the G5 with par readings and mounting heights. It’s worth a watch, while it won’t be exactly the par you’re seeing it would at least give you ballpark numbers.

I have never had a coral go black from being burnt. I have seen corals bleach white, and stn from light levels though.

I will take a photo here.........

That burned side was facing away from me so too bad I didn't notice it earlier

It looks ok from what I can see under the blue lights. If it was light related I would have expected the top of the coral to be showing the bleaching. I’d leave the lights along and give it some time.

 

[Gordonm]

In the same area and more under the direct light I have forest fire digi's, green slimer, and other encrusting monti along with even zoanthids and also a setosa.

 

[Gordonm]

Well it didn't bleach at the top. Just a scorch on the side.

 

[Gordonm]

I have a new acro on the sand bed still adjusting so I'll leave the lighting alone.

 

[Gordonm]

Could be having my nutrients a little low and my alk high too. Still adjusting my dosing.

What are you running your ALK at? What is your Po4 and No3?

 

[Gordonm]

Been getting my alk down to 9.8 but the other day it went back up to 10.9 because i think my kalk solution was a bit stronger when I refilled it. It's been higher than that over the few months so have been making some progress. My N03 is 1.0 and P04 tested at .04 yesterday.

Alk high , recommended 8-9
Do not dose for 3/4 days and recheck before resuming dosing

 

[Gordonm]

Yes I know. I don't want the alk to drop to fast though. Not dosing for days will also drop my PH further which i don't want. I'll just adjust my dosing gradually.
