How do I acclimate my shark to brackish?

[Mystus Redtail]

I just picked up a bull(Columbian) shark that has been raised in FW and I want to switch him to Brackish b/c I read that was best for them. What do I do? drip method? for a day? or slowly raise tank salt levels? I have no idea. Please help.
Thanks

PS I'm thinking of adding a snowflake eel that is also kept in FW and convert it too, same remedy?

Is the tank BW already? If not & it's empty, then fishless cycle the tank at FW & raise the SG .002/weekly water change. If it is already BW, drip acclimate no faster than .002/hr.

ok, well, its cycled fw right now, but no fish in it as of this afternoon. so just raise the SG .002 weekly. cool. thanks.

You can raise it slower, if you want.

I add 1/8 teaspoon a gallon every water change every 3 to 5 days(10%) so you don't kill off bacteria but .002 sounds right. I always have done it this way . so first waterchange is 1/8 tea. then 1/4 then 1/2 then 3/4 after I get to .008 then do regular change every 7 to 10 (20%)
