Hiposalinity issues????

[daniella3d]

I did the same without any problem. It is rising the salinity that is dangerous.

But are you sure of your salinity? are you mesuring it with a good calibrated refractometer?

Your fish might be contaminated with Velvet or another parasites that is not affected by hyposalinity or they might be already too infested in their gills so by the time the hyposalinity take its effect it might be too late?

Many possibilities here as you see. Did you test for ammonia? Do the fish have enough oxygen? because if you put a bunch of fish in a 20 gallons tank without any areation, they might just die from low oxygen.

Was that too fast? I read that lowering the salinity can be very fast, without any damage to th fish but raising salinity should be done very slowly in a matter of days.

It's not hippos, it's hypo for hyposalinity.

I think the affected fish are copperband and cleaner wrasse.

Once ick is out of a tank and the tangs are free of it, it will not return. I had a hippo tang and of course it got ich at the beginning but after treating him with hyposalinity it never returned, not even in periods of stress.
