thks for the detail explanation. if i understand it correctly, the rate ca /alk are being use up are not the same. i need to dose more of both calcium and alkalinity to stabilize the system, even though ca is still high.
My alk range from 7 to 8, ca 480 to 525What exactly are and have been the values?

This was helpful as I’m having a similar situation Regarding alk reduction. I believe it’s due to the large amount of coraline algae on the live rock that I started with and added over 8 corals.
My tank is only 30+ days Old. I do 25% water changes per week. my alk has been around 7.5 but cal stays around 420. I’ve been dosing around 10- 20 ml per day and cal every other day 10-15 ml.
my mag is 1290 and have been dosing 15-20 ml daily.
