when you guys do your water changes do you add anything like cal or alk/mag? cause im thinking if i do a 25% water change my alk might drop form 11 to maybe 9 or 10. Is this safe?
 
Probably a good idea to match your water change parameters to your display tanks parameters...
 
I dont but my salt has the same alk as my tank and ca is just a little higher. If your salt mix has lower alk, ca and or mag then yes you should add to it so it matches or slightly exceeds that of your tank. That being said I would be changing to a better salt with higher levels. For years I used RC and before that TMPR and a few others. When I had issues with RC and need ti switch salts I did a lot of research in different salts to fine one that met all my needs. TMPR and H2Ocean made the top of the list, it came down to local avaiblity H2Ocean was easy to get locally and Pro Reef was not.
