Section of blasto dying

[Ef4life]

Over the past week a section of my blasto colony has not been looking good. All grown out from the same single frag I bought years ago. A few times a year I get some polyp bail out when they are overcrowded, and I sell those polyps as frags. I though that was the same thing happening but I’m not sure now, they seem to be losing flesh. Any ideas as to what’s going on?

Check PH recently?

What Calcium test kit? Depending on the kit and how people read the end point you might be lower than you think. Just a thought.

What are the brown things right near the affected patch. Need a better picture of them. If they are hydroids or some sort of anemone they are annoying that spot

 

[ZoixDark]

Yeah i just noticed, are those palys in there? They could be stinging the blasto.

It’s Red Sea pro, it’s been fairly consistent for me, but has been lower for the past 2 months or so, it used to be 440-450 consistently.

Ph I ran out of the test, but it typically was 8.1-8.2 when I was testing

I believe they are some type of hydroids but they have been there for years and never been an issue before.

i did do a chemiclean treatment 2-3 weeks ago to get rid of some cyano, did a 15g waterchange when it was done. I don’t recall if this started before or after that treatment.

Here is a hopefully a better photo from a few months back, dslr vs my iPhone. You can see the hydroids right next to the blastos and no bother at all.

 

[ZoixDark]

Maybe they've become a bother.

Looks like an infection to me

Anything I can do to treat it? I can’t pull it out it’s grown onto the rock along with a bunch of other vitals.

Not sure how you would treat it in the aquarium. The only thing I can think of is using a pipette with peroxide in it. Turn all pumps off. Peroxide is heavier than water and as you slowly release it it will float down and then you can treat the area with peroxide. I did this and saved a frogspawn from brown jelly. This would kill any infection on the surface of the coral. Wait a 5 or so minutes before turning the pumps on again

Did you use the 3% peroxide to spot treat the frogspawn?
Was the peroxide diluted?
Any affect on the parameters after spot treating?

 

[Auto-pilot]

I used 8% actually but in sure 3 would work. It will not affect parameters but sps corals do not like peroxide. It will stay localized if you dont put the pumps on. In minutes the hydroxide will turn into water and hydrogen gas rendering it harmless.

it may be infection , I will get it out and cut the affected area with good margin and dip it with dip solution

Curious how you made out with the colony as I am experiencing this issue with my blastos as well. TIA!

It made a full recovery and has grown more since.

Great to hear!! Cut and dipped?

I'm also curious, also since those both look established, have either of you experienced this before? Thanks hope you get good help and the same results!

 

[Ef4life]

No, I did not do anything honestly.
The rock it’s on is one giant piece basically 1/2 the aquascape so removal is really difficult, especially with the blenny that hides inside. It never spread to the other 2 sections of blasto so I just watched it, and I kept the tank clean, ran some carbon etc. may have been a reaction to chemiclean or something.

- I did just cut a small section off about 20 minutes ago, a few polyps in the shade we’re bailing out of the colony.

I’ve not had something specific like this happen before to my blastos.

I have experienced coral decline due to laziness, lack of maintenance, dosing etc. but this was different
