This totally depends on how much hard coral you have. If you have lots of lps
you will probably have to maintain calcium/alkalinity. If you dont, then just pwc
are all you need as melosu mentioned. Kalkwasser is not the only option to raise calcium. There are also 2-part additives. If you use kalk
, keep an eye on your ph because too much kalk
will raise your ph quickly.
