Hi Bro,
The correct parameters based from the article I read are as follows:
PH should be between 8.1 ~ 8.3
Alkalinity between 7~11 dKH.
I am still on my 6th day cycling the tank and will keep monitoring water parameters.
Based from this article: http://reefkeeping.com/issues/2005-03/rhf/#9
"if the pH is above 8.5 and the alkalinity is not above 4 meq/L, then the aquarium is not fully equilibrated with carbon dioxide in the air."
But my alkalinity is above 4 meg/L, so i'm still reading more on this.
For alkalinity, I will start doing 5% water changes and continue to monitor.
Hope anyone can also provide inputs on this.
