Killing ick on fish with inverts also in tank?

[demonte1997]

I have a nasty ick outbreak on my tetra tank. Already lost 4 out of 8. I turned the temp up and added a bit of salt. What else can I add that won't kill the invertebrates I have in there? The inverts are red claw macros.

I hate ick. So lame...

Irradiate, irradiate, irradiate.

Adding a UV sterilizer with a very low gallon per hour flow will kill waterborne parasites (approximately 5 gph per watt on the UV bulb). This will not kill anything that is associated with substrate. Run it 24/7, for a minimum of two weeks.

Another method that worked for me when I had malachite-green sensitive fish in my tank was a VERY aggressive water change cycle. 50% a day for two weeks. You'll want to vacuum the substrate as well. You will also want to replace /portions/ of your biofilter as you do this (but not all at once!). The idea is that between the UV sterilization and water changes, you catch the free-swimming phase of the ich, and eventually dilute them into non-existence (or at least low enough to not be detectable).

You need 3ppt (parts per thousand) saline concentration to kill emerging ich, nothing kills ich while on the fish, only the emerging stage is vulnerable and implodes with a 3ppt concentration. Under 3ppt is ineffective. 3ppt will make the water taste salty, yet is much below the 35ppt of sea water.
You don't mention what kind of inverts, many can tolerate 3ppt if you increase concentration gradually.
Becoming ich free takes time, the protozoa must run through all its life stages, can take weeks.
