Question about hospital tank/fowlr at the same time.

[tony_3a]

Hey guys, Im curious if it would be ok to use a fowlr system as a hospital tank as well?

Why i ask this is because currently i have a 90 gal with a koran angel in it and a coral beauty angel, and they are eating my corals, so I am looking at buying a new setup and putting it in the basement and using it as a hospital tank where i could add copper to it and lower salinity to battle ich and such.

My main question is would it be hard on the two angels to be in a tank that every couple months when i bought a new fish or had a sick fish to be treated with copper/lower salinity?

Thanks a lot guys.
Tony
