Marine salt V.S. API aquarium salt.

[SnowRider]

I've been using API aquarium salt to make my tank brackish.
Should I be using Marine salt instead?
My tank is basically mollies with the exception of 2 peppered Cory catfish. Plus some Zebra snails and ghost shrimp.

Yes, you should use marine salt mix to go brackish. However, corys aren't brackish, so don't with them in the tank.

Since I've already dumped a bunch of the aquarium salt (API) in the tanks (table spoon per 5 gallons give or take) what would be the best way to transition over to the marine salt? TopFin sea salt mix is what I have.
How many parts per gallon should I be putting in there for a 20 & 30 gallon tank?
Any info appreciated. TNX meng

Use a hydrometer and figure out what level of salinity you want to maintain. Then on your next waterchange use marine salt instead of aquarium salt.
