I am trying to figure out how much cal and alk to dose daily using my BRS (bulk reef supply) two part kit. So for the last week I have been measuring my Cal and Alk daily. For the first my cal started at 450 then went to 440, then 430 over the first three days. I did my weekly water change after day three. When I measured Cal on day for it was back to 450 and has not changed since. (I use instant ocean salt). Alk has been 10dkh the whole time. I did dose Cal and Alk one time last week per the maintenance guidelines that BRS says to use (.4ml/gal of solution for both.)
My params as of today are:
Cal 475
Dkh 10
Mg 1350
ph 8.0
salinity 1.025
ammonia 0
nitrite 0
nitrate 15
I have a mixed reef of zoos, acros, birdsnest, caps, and montis. My main orange cap and one of my montis are doing terrible. I have no major colonies (all of my sps are frags).
Is my tank just not consuming Calcium. With a Cal of 450-475 shouldn't my rocks be purple-ing up faster? Should I just not dose anything?
PS all testing is done manually by titration.
