Question about DT fallow and equipment

[mjaquarium02]

So about a month or so ago I saw both of my clownfish struggling to breathe. They were breathing fast, not eating, staying on the sand, and they were definitely not acting like themselves. The thing is that I did not know what was happening. Besides those symptoms, they looked fine. No white dots, no slimy coat, nothing. I also checked my water parameters and they looked good as well. I do have a cardinal fish but he was completely okay. Either way, I was running out of time for sure because my clownfishes kept getting worse each day. I kinda played my luck and I built a QT tank and dosed some copper. Again, I didn’t know what was happening and I wasn’t even sure if copper would work, but luckily it did!!! I just finished dosing copper to all of my fishes. They’re doing well. I don’t know what this mysterious disease was, but glad it is over.

Now my question is: Since I don’t know what this was, my safe bet is to let my display tank fallow for 40 days more. The thing is, what about my filters in my display tank? I have a sponge filter, carbon, and biomax filter media. Do I have to replace everything? What will happen to the beneficial bacteria that I already established with it? I still have some invertebrates including a cleaner skunk shrimp in my DT as well as some corals.


Any info helps! Thanks!

As long as you don’t have any fish in the tank, just leaving it fishless for 60+ days will take care of anything.
