anyone know the measurements for Bioactive tapsafe?

His all

I have a 19lt tank, with 2 variatus platies in it (yes I know this tank isn't big enough, stupid pets@home gave wrong info). I've got Bioactive tapsafe to put in the water during water changes but the measurements are waaaay off. It says on it to use 1 inner capful for every 45 liters well my tank is no where near that size and I've only been doing partial water changes. 20% water works out at around 4liter's so how much of this taps are would you use?

There has got to be a simple way of working this out my tired brain won't function - I'm blaming my night shift I've just done

Your help will be appreciated xxx

You will need a syringe to do it easily, but a cap full is generally 5ml. This means you will want to use about half a ml for your water change.

Just be sure to measure it to make sure the cap really is 5ml
