During each water change, add pre-mixed brackish water. If you do a 50% water change, and add 1.004 brackish water to the tank, then you should end up with 1.002 total. The math is easy. Always pre-mix with powerhead and heater in another vessel (ie trashbin).

what kind of eel do you have?

its a gymnothorax tile...sold as freshwater snow flake eel or freshwater morey eel....i did my research befor i got it and found its actuly brackish to full marine. it was in a freshwater tank at the store so i put him in a freshwater tank and am going to bring the levels up....now i understand i should only bring it up .002 a week im using instant ocean...is the way u explaind this going to bring it up more than tht?

It should if you calculate the salinity of the current water and the new water.

IMO you should bring the salinity levels up to marine water. Easier and more practical that way since you could use a skimmer and possible add a refugium to grow macroalgae (both prolongs water changes).

Moderate to high-end brackish water is pretty expensive when you start doing the water changes.
