It's good habit to never add anything to your tank that you aren't testing for. Adding Ca
without testing (you mentioned alk
in another thread) is a really good way to start a tank with your water parameters really out of whack. With Ca
between 380 and 420, and alk
between 8-12 dkH
, coralline will grow just fine on its own.
Adding PurpleUp will not change the evaporation rate.
