bite marks or is coral bleaching?

[undertai]

I move from a AI hydra after I moved to a new place, so I decided to try the AI Prime. After a couple months I upgraded to an XR15 for my take I have had it at around 80% on a Red Sea Nano for a couple of months now. Started at 50% and slowly moved up to 80%, as this light is way more powerful than the AI Prime. The last couple of weeks I have noticed the marks on this coral and 1 other frag. I moved the frag and it seems to be coloring backup, I don't see any red bugs or any other pest in my tank that would cause this. The was a large very large piece when I bought it I have broken it into 4 pieces and put in different places around my take. But this is the only piece showing bite marks, and its not directly under the light.

This piece sits near the front of the tank, I have a piece that is closer to the light and its showing no signs of this.

Looks like bite marks to me but how's your Alk level? Any swings?

+1 looks a lot like aefw bite marks

bite marks 100% dip that sucker

I would bet big money on aefw.. there are classic bite marks on that coral..
I'd remove the two corals that look like that and dip them.
Inspect the bath water after for aefw.
Give the coral a good shake in the bath. Sometime the aefw get shocked but don't actually fall off the coral. A good shake will dislodge them.

I hate to be extreme, but with AEFW if you dont dip every smooth skin acro you will not rid the system. You need to pop any eggs you can with a tooth brush and dip a lot. I beat a very mild case of aefw. I was very agressive though. I scrubbed lightly every inch of my acros and plugs. I then dipped daily for two weeks. I am now acro AEFW free and fighting a ULNS because my nitrates are 0. Its always something.

I do not see eggs, so that is only thing that throws me off with your picture. Normally AEFW lay very visible eggs.

Also i did lose one of the Acros, due to this method.

AEFW do not just affect smooth skin Acros , you need to dip every acropora in the tank. As well I wouldn't advise anyone to dip acropora once a day as that's only gonna stress the corals too much and is not necessary. Dipping once a week for a minimum of 8 weeks is probably best.

I got a one inch frag from a shop the other day and didn't notice the bite marks until two days later. Matter a dipping schedule with both interceptor and revive the coral has gone from looking like that one to almost healed I less than a week. I would say it had at least 30% tissue loss from the bites. Looked exactly like the pic.m I also dipped all the corals within a foot of the infected piece. I hope the aefw didn't get further than that lol

Would like to see if there are alk swings but looks like AEFW to me too. I am currently battling them but I think I am winning . 2 more weeks of dipping for me . I dip every acro

I didn't know interceptor killed aefw.?

My alk is around the same goes up and down between 9 to 8.5 dkh. Depends on the time it takes between water changes.

Aefw

Dipping for Aefw seems like it should be fine weekly if you only have frags, but, what about larger encrusted colonies that can not easily be removed?

 

[Coralmassa]

I had to take a large rock with several largerish colonies out to get rid of red bugs, just plunked the whole thing in a bucket with a powerhead and heater without removing the colonies. I guess if even that is too much you would have to dose directly to the tank. There a multiple threads on here on how to do it. If you can get interceptor, that seems to be the most popular method. Some propels use bayer or other insecticides that contain concentrations of the active ingredient. I prefer interceptor chewables be use the beefy protein in the pill encourages better or after a coral has been stressed with pest

If u have no inverts then fish and other corals won't be stressed, u just have to get the dosage right. Otherwise U can try to remove your cuc or any shrimp to a qt tank for the duration of the dosage, then return them.

Interceptor will have no effect on aefw. Only red bugs and with that just treat the tank.
