do u need to dose calcium, alkilinity and magnesium in a softy tank?

[brob22]

if all the corals are soft corals is thier a need to dose those supplements.

or do the lps corals need calcium

 

[xlzerolx]

If you have LPS or clams then yes. Everything with some form of "hard skeleton" requires maintnenace of calc, alk and Mag. Even if you have chaeto or other forms of macroalgae as one of your nutrient export you will need to watch your mag levels as they will drop over time

Even in soft coral only tank you need to watch for alk, in log run it can drop down too low (own experience).
