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
