Disintegrated jellyfish

[Don 42]

This tank was set up with 3 small jellyfish 2 weeks ago. The tank was cycled properly. The salt was added to the water for a water change and was kept overnight before testing. The chemical parameters of the new water were identical to the tank water. A successful water change was made a week ago. The tank was doing great. I checked the chemical parameters of the tank every day especially for ammonia to make sure I was not over feeding them. Yesterday, when I turned on the lights, the jellyfish had disintegrated.
The chemical parameters were: Ammonia 0, Nitrate 5. Nitrite 0. PH 6.5 (was 8.0 before). Salt 32, Temp. 69 F.
I searched the internet and found out that none of my parameters would have caused the disintegration.
I would greatly appreciate your comments on this matter.

Video would be helpful but remove id disintegrating and monitor water parameters

If you re-post your question in the fish disease/treatment forum you are a lot more likely to get some answers. Jayhemdal or vetteguy are usually very helpful for fish disease but i dont know how much they know about jellyfish.

Don’t know much about keeping jelly’s as they are not super common in the hobby.

Welcome!!

Here is a link to the area suggested to post this question too. Maybe someone knows more about Jellyfish. I know they sting me when I swim near them and that's about it...

I don't know much about Jellyfish, but a pH of 6.5 is already considered slightly acidic and saltwater is usually slightly alkaline. A whole lot of chemistry changes when the pH drops (or rises) too fast. I can't imagine that organisms that are used to the "stable" and alkaline pH of the ocean are good at tolerating such a pH drop.
