What could be the issue with acro?

[PegasisR]

Acro is light in color and it’s skin appears powdery, it also has some skin missing in two different areas(top left of large branch and the other one at the middle). Dipped for aefw and nothing fell off. Parameters are rock solid as other sps are doing swimmingly (haha). What could be the issue? Leaning to light being the culprit and maybe it got damaged from cleanup crew

Check for white bugs, they are nearly microscopic, really mess with coral color and PE. Unless you dip in bayer they usually pull through a dip. Best way to check is with a phone flashlight in the middle of the night, given you have a good eyesight and 15 minutes to spare staring at your corals.

ill sit and watch! one thing though, bayer is out of the equation... anyother dip i could use and what would be the dose?

If you have them in your tank, it’s Interceptor time, you’ll see PE and color almost immediately. But if you don’t see them on any acros, I would look for other reasons. Easiest acros to spot them on are dark validas, or green ones. Anything that looks like a tiny white or tan speck, almost like a microscopic piece of detritus that moves agains the current on an acro is a bug.

Stared at affected Coral for a while now and I can’t see anything. Had a magnifying glass up to it against the tank glass and couldn’t find anything either…

IME the initial damage from bad bugs starts in the shaded areas of the acro. If the damage is worse in the shade areas it’s time to find some interceptor or dr G’s.

Too much linear direct flow can sand blast tissue away as well. You absolutely can have too much of the wrong kind of flow

 

[The Farmer]

How are your parameters? ALK, calc, mag, nitrates, phosphate?

 

[PegasisR]

How are your parameters? ALK, calc, mag, nitrates, phosphate?

Alk 8.5
Cal 440
Mag 1350
N 10
P .06
So 1.026

btw every other acro is having a wonderful time, the one beside this one is growing very well. No damage on the others either

The big white spot you can see is a shaded spot, also am I able to dip with dr.Gs (if so how?) or do I need to do the tank treatment? As well other acros like it are fine and shaded areas seem good from when I looked last night, could white bugs affect digi’s as well or just acros?

In tank treatment
1.5-2mls per gallon

Looks like slight STN. Stressors such as increased temperature either modify the structure of the coral microbial symbiotic community or trigger the production of virulence factors. Temperature stress can increase chances of coral disease development in several ways by creating stress in the coral zooxanthellae and decreasing its resistance to infection
Some possible triggers of infection are:
- Alkalinity spike
- Temperature spike
- Salinity spike
- Low dissolved oxygen
- Poor water quality related with phosphate levels up to 5 ppm
- Change in water flow
- Additions of sand
- Changes in brand of salt
- Bad test kits giving faulty results
- Levels of minor elements such as Iodine, Potassium, Strontium
- Light intensity
- - Changes in water flow
- Addition of new corals
- - Pesticides

Thank you :) and if I were using interceptor, which one would I need? I have a 139g system

I did change my brand of salt but i did it slow through AWC, temp could have done something but other corals are happy, I lowered my flow but still is enough to whip the acros indirectly, light intensity did change over the course of 30 days, whenever my tank evaporates salinity goes up to .027-.028, sent out an icp for toxic levels of minor elements but that got lost in mail, added in a frogspawn, ORP is at 316 but everything else is fine

also want to add that I forgot to change my co2 media and ph dropped from 8.3-8.4>7.9

A few changes occurred that could be the triggers

How was the affect of dr g on fish? I know inverts will take a hit

 

[Charlie’s Frags]

You need the large dog or cat interceptor 23mg

I do an aggressive dose
1 full per 50g every time I add new corals

Crabs and shrimp will be toast with either
Snails and fish act like nothing happens

also that big white spot in the middle of the acro is stumping me… that was the only spot there maybe a month ago and then only recently did I see that other white spot on the large branch

How are fish? And 1 tablet of 23mg per 50g?

If you don’t mind, why “additions of sand”? Cheers
