Fish healing rate from flukes

[Reef Wizard]

Good New year morning,

Is there a general rule of thumb for how long a fish will stop being irritated by particulates in the water?

I have ran my Convict through 35 days of Hyposalinty at 1.009 SG due to Prazi not really working on flukes anymore in my experience (also is anyone else finding this to be the case with prazi)

When should I expect the shaking and scratching to stop?

I am confident in my method and testing as I have completed this procedure on my Foxface who is clean from flukes.

Hypo will not be effective on flukes as it will be with ich. For flukes , you want to run two treatments of prazi 9 days apart with added aeration. Our recommendation with flukes:
remove any type of carbon that you have running to allow Prazi to run at full strength which will be an initial treatment for an 8 day interval, change water and treat again for one more dose 8 day interval. To be safe, treat at 85% of recommended dosage. Add air stone as prazi will reduce oxygen

I did run three doses of prazi before this and he was still scratching pretty aggressively.

He has moments kind of like when a dog randomly jumps up and starts scratching itself.

As you may know, multiple prazi doses become increasingly less effective due to bacteria growing that consume the prazi faster, and often before it has a chance to work. Also, prazi doesn't kill fluke eggs, so it needs to be re-dosed at a schedule that tries to kill newly hatched flukes, but before they have a chance to mature and lay eggs of their own - the timing of this is all just a guess, I use 8 days, with a range of 6 to perhaps 10 days.

Hyposalinity effectively kills live bearing and adult egg laying flukes, and holding hypo longer than around 21 days kills any newly hatched flukes, stopping the life cycle. I use hypo exclusively for Neobenedenia flukes now. The only caveat is there are some brackish water flukes that can survive hypo. However, in my experience, these are rare, and mostly seen in systems that have had wild caught brackish water fish added (usually public aquariums).

Now - why is the convict still flashing? Tough to say - it could be particulates in the water that land on the fish, causing it to react by scratching. In some other fish (wrasses mostly) the flashing is a behavioral thing.

With all this in mind if you dose prazi how long does one need to wait for the bacteria to die off before its effective again? To potentially dose again

Or does it need a complete tank teardown and cleaning?

Nobody really knows how long the heterotrophic bacteria remain hyperactive after they have grown to consume prazi - but it is at least 4 months (personal experience). Most people strip the tanks and reset them if they plan to run multiple prazi treatments. You can dose 3 to 5 times before the prazi is pretty much rendered useless. The dose can be increased to compensate, that that's risky since you cannot really tell how much is being decomposed.
