Running hypo indefinitely

[ecam]

Hey guys. I've been running hypo for the last 3 weeks and my fish have never looked better. I'm thinking of staying here and just running fowlr. Since corals don't like me!!!

What is the downside if any to keeping fish in such low salinity ?
all opinions are greatly appreciated

Aside from brackish water fish, eventually the lower salinity will start to be hard on the fish. I remember reading an article back years ago so details are a bit fuzzy, but basic bodily functions are affected. For example homeostasis, kidney function, swimming bladder. Some as I recall are actually easier for fish others harder. I recall the overall idea was that it was much easier on fish than chemicals but would be adverse over a longer period.
