Ammonia (NH3) is oxidized to Nitrite (NO2), and then
oxidized further to Nitrate (NO3).
A good rinsing should be all that you need.
Basically you have sodium (Na), and Nitrate (NO3) to wash
out. Both are naturally found in the reef aquarium. Salt
is sodium chloride (NaCl) When you make your first batch
of salt water in it, let it sit for a few days, and then
test for nitrate. If your good, your good.
