Replacing filter media/deep clean tank after disease?

I have a tank that I have been treating with Paraguard to address some unknown parasite. I'm at the point where everyone is behaving normally with no signs of being sick or stress but now I'm wondering if I need to replace the filter media and deep clean the tank to get rid of any lingering badness. I know that by replacing the filter media, it'll essentially re-cycle the tank so I want to avoid that but the last thing I want to do is get the remaining healthy fish sick. I haven't thrown the carbon back into the filter yet.

So what are your normal protocols after dealing with disease/parasites?

Some ideas that I'm bouncing around in my head:
-Replacing filter media, taking down the tank and bleach dipping all live plants and equipment and replacing the substrate
-Leaving everything as is, just doing a pretty large WC, throwing the carbon back into the filter and gravel vacuuming where I can (trying to get my DHG to carpet so have to tread carefully!)

At the end of the day, my main objective is to keep my remaining fish alive and healthy ( hoping my new fry didn't contract anything!) so I will do whatever it takes!

Thanks in advance for any advice!

 

Bumping this up for you

 

I've never actually done this, but I would take out all the media for replacement and bleach the whole thing with high concentration while it's running might work. Then running it for a couple weeks with prime/safe with a several complete water changes. Maybe you can reuse ceramic media and gravel/sand by cooking them in an oven. Just a crazy idea I had.
You'd need some place to keep your fish in the meantime. Take out live plants for separate bleach dip of course.

 

Hmm I didn't think of running the filter with bleach but that's definitely an option now. I am just gonna toss the media and gravel though but its amusing to think of the expression on my man's face when the oven timer goes off and he comes running into the kitchen expecting cookies and I pull out a tray of gravel and filter media instead LOL.

If you do that consider running the bleach for a day, but take out the media first, the deepest pockets of biofilm/biomatter will be more likely to survive the bleach. The outer layers of organisms will serve as a meat shield for the inner layers.
