Medications to add to Display Tank

[67chevellemalibu2]

Are there any preventative safe meds with inverts that can be added to your display tank when you add a new fish incase there might be some sort of parasite?
No I don’t quarantine, nor I am I looking for a debate.
I have a FOWLR tank.

Pretty much all ich/velvet meds are not Invert safe. At least the ones that work anyway.

I would, not saying you should, but remove the inverts and use copper power. Check with a Hanna meter, 1.75 to 2.

Most big tanks, the ones in hotels, restaurants, casinos etc use copper periodically.

You can watch absorption with the meter, and dose accordingly.
