War Coral Bleaching Part 2

[HumuhumuFan]

I posted a while back about my main War Coral bleaching, it recovered beautifully.

Yesterday everything in the tank looked fine. The day prior I was manually removing green hair algae, which continues to be a problem. Today I got home from work and two of my smaller War Coral frags look totally and partially bleached.

Any ideas? All I can think of is that I accidentally scraped it with my finger nails while pulling at the GHA, or maybe I got a pinch of sweeper tentacles with the algae and it tore some flesh off. Sucks, it was doing great, lots of new growth.

Is it possible that some salt creep landed on it? That stuff will burn holes through corals.

It’s possible, but I don’t think so. I wasn’t aware of that though so I’m glad you posted that. I will definitely be more careful with salt creep in the future.

It falls in like a silent assassin my friend.

Looks like trigger bite marks.

Possible causes:
Stinging from another coral.
Object landed on that area
Bright light
Low ca and alk

My trigger is in a different tank. This tank has 2 clowns, a Peppermint Shrimp, hermits, snails. I have never seen the peppermint pick at corals and all the rest of the frags are fine. Seems like he would pick a little at all of them rather than focusing one down but I don’t know.

I noticed my ATO output was kind of close to that area. Is it possible they got melted by RO/DI blasts?

Id say no but in this hobby, we rule Nothing out !!

I would stick with what Vetteguy53081 has said ,, do a water test ,, check everything ,, nitrates ,, phosphates ,, Calcium ,, Alk and even Mag. I would see if you can borrow a Par Meter ,, corals can die quickly because of to much light ,,, they can also die from not enough light ,, that takes a bit longer ,, your battling a hair algae problem ,, along with coral die off ,, the reason for this might show up in a water test ,, you need to question you RO/DI water source also ,, don't dismiss the Par meter also ,, its important ,, it really is ,,, not finding out what is going on ,, is going to cost you corals & $$ ,, I have seen people leave the hobby ,, all because they couldn't find the problem ,, post up any results you get ,,

There are smart people here ,, use them

There certainly are! I kind of lost track of this forum when the phone app stopped working I will post an update photo later. Good news, the bleaching stopped and the piece recovered nicely!

As promised.

As promised.

what was the solution?

Only if a drastic change in salinity-temp-ph

this piece looks perfect. Wait til it gets to the size of mine
