If my memory serves me well, that is beyond the tolerance of some plants.

Do you mean 3 ppm? 3 ppt = 3000 ppm... the fish only need a few ppm to combat the nitrite in any case (if that's why you are suggesting it I assume).

If his nitrite is 5 ppm then he would need around 30 ppm chloride from the salt to prevent brown blood disease... again, not sure if that's why you are suggesting it, I'm just guessing...

I don't recommend adding salt into your system willy nilly. Ask us first on here so we can make sure you won't kill everything!
