I have a molly tank, with some ottos. i added salt a month ago and was wondering how often should i add more salt? My tank is a 10 gallon, thanks
 
You can't keep otos if you're going brackish they're FW fish that require soft acidic water. You're also probably not using the right salt, you should be using marine salt, not aquarium salt.
Get yourself some marine salt and a hydrometer, you should probably add about 2 tablespoons per 10g for mollies.
 
There is another thread going right now about cobverting from freshwater to brackish in an ongoing tank. Mrsofty2, I believe is doing it. There is great info in it.

But yeah, find a new home for those ottos before you start.
 
It's a waste of $$$ on a hydrometer for 2tbsp/10g. That amount of salt won't even register. That small amount of salt won't really bother the ottos. Much more than that & the ottos will have to go.
