Learned my lesson early in reefing

[bombero11]

Well I have lost all my fish except my first pair of clowns

I had a purple dottyback, firefish and 3 reef chromis

The chromis all starting dying one by one until within days
I noticed one of the three looking week gasping for air, hiding and had a white film on his body.
I assume it is velvet?

All my parameters are great
API test kit:
Ammonia nitrite and nitrate are all 0

Ammonia was .25 a die after a fish was sitting on the bottom of my tank when I got home
But went back to 0 the next day

Red Sea test kit:
Alk 9
Cal 450
Mag 1340
Ph: 8.1-8.3

My display has been running for 3 1/2 months
Red Sea reefer 350

I already started cycling a 10 gallon for a QT
And buying a used 30 gallon this weekend to have a bigger qt for bigger fish

My question is once I transfer my remaining clowns into my qt once it’s cycled
They look healthy as ever and eat like pigs
What do you y’all recommend i dose, copper? Other meds?

I’m not exactly sure what parasite killed them but going to go ahead and run fallow for the 76 days
And quarantine my fish from here on out
Luckily I didn’t lose expensive fish, these were enough to learn my lesson quickly

Any help is appreciated

You may have a couple of things going on at the same time. The "white film" mentioned is usually a symptom of a bacterial infection or Uronema. If is was Uronema, the tank has to be sterilized. The parasite is not dependent on fish for food and can live indefinitely in the tank. As for the remaining clowns, treatment with copper and then General Cure will take care of velvet, ich, uronema, brook, flukes, worms.

So remove all corals and inverts and bleach the water with the sand and rock still in it?
There’s not much information on uronema
