My clown fish have Brooklynella

Nope, same issue, no pH buffering. You can use bottled spring water if you raise the temperature....non carbonated of course!

Does distilled water work?

Looking at the pic, I see nothing.
What makes you think your clowns are sick, or have brook?
Have there been any behavioral changes?

Not saying your wrong, but you seem a bit freaked out, and you need to diagnose correctly the help them the most.

Get some good pics for the members to look at especially Jay and provide some detail at what you observe.

You had these fish for weeks and they were fine unless you recently added something wet in your DT.
