Is my prata and bubble infected by some disease?

[koniyakutz]

Hi guys,

My prata and white bubble has been in my tank for about two months and they were doing very well until I changed to Redsea salt(LFS ran out of Coralife and my tank was due for a water change).

The prata was the first one to show signs of problems, it started expeling zooxanthellae and within a few days it turned from greenish-brown to a very pale colour, I also noticed some black growth on its skeleton. Dispite that, it was still expanding fully and eating market prawn.

Then, my white bubble who used to open really big started shrinking and I too noticed this black growth on its skeleton.

I also lost a clam which was doing well in my tank.

Has some kind of coral disease infected my corals? All these happening within a few days, I have since did a big water change using Coralife salt.

Currently feeding my bleached prata with market prawn 3 times a week, will it die? Can it be saved?

Thanks

This was how my prata and white bubble looked before the water change with Redsea salt.

OMG, they deteriorated so quickly after a water change with another salt.

Darn! I shd have went to another LFS to get the usual salt.

my deepest condolences. there are many factors to consider, changing the salt might just be one of them. Honestly, i am changing my tank water between mix of NSW and synthetic salt but doesn't show any signs of problems yet although some reefers advise me not to.

hi, i have been using red sea salt for past 9 months and have never exp such encounter before....

1) chk expiry date on salt packaging,

2) did u introduce the freshly mixed water immediately or after abt several hrs of mixing?

[koniyakutz]

I poured the saltwater in a few hrs after mixing.

U might want to chk the water parameter of Red Sea salt..... like the KH and calcium level. I have chk the water parameters of Coralife salt after mix before, they are not far from what the package state, KH 10 with around 400ppm cal.

If what you observe is true (not due to any other factor) then high possibilities that the water parameters is out.

[Reefaholic]

Normally it is due to drop in kH.

(Just my experience and thought)

I cant say for sure what is the reason but if you are feeding small pieces of shrimps to it, then it should recover in due time. Of course, you must ensure if the shrimp are swallowed in the first place. Had a prata similar to yours a while ago, fed it consistently with shrimp till i sorted the problem.

As for the bubble, I think most importantly is that you must observe if the tenacles are extended when the lights are out. Normally, if they do, then they should be alright for now. You can try antibiotics if the bubbles start to rot. But please use it responsibly

Just my opinion.

Hi guys,

I dipped both corals in lugols solution and also, fed them with market prawn on alternate days.

The bubble is recovering, prata started expanding and is eating well. Hope it will colour back again.

Yep, I left the coral in a plastic pail with saltwater + lugols for abt 5min.
