How much would i use for a 12l tank?

Use the instructions on the bottle and you won't have any problems.

Is this better than api stress coat?

Hi , not sure which is better for getting rid of chlorine and heavy metals , probably the same for that but the stress coat also helps the fish not stress so much and also helps fishes scales to heal better, essential tho also helps to keep any ammonia, nitrite away and also keeps nitrates down so really depends what you are wanting to use it for, 👍
