For some reason all my tiger barbs developed cloud eye and some looks like theres white stuff on the eyes, and some white stuff on their bodies + fins, like tiny white minute dots. My water is pristine with a ac50 and a eheim ecco canister for my 29. Could it be ick as I read about?

My water params:
amm - 0
nitrite - 0
nitrate - 10

I don't know whats the problem, and i added aquarium salt and turned the temp up but no progress, 1 die each day. Out of 8 tiger barbs i had, 5 died so far, 2 died today, and now I got one left.

My main question is,

1. is it safe to throw out the last dying tiger barb, and buy another group of fish before my bioload decreases to accomodate my one last tigerbarb?

2. And, will the new batch of fish catch ick or anything??

3. Since I had the salt dosage in the tank still, should I remove it with a waterchange before I add the new group of fish? How much % waterchange?
