Yet another CA question

[Joe Fish]

Well, I just got a new CA test kid(salifert) and reef advantage calcium. It says to add 5grams per 40 gallons and not to dose more than 10grams per 40 gallons. So if I dose 10grams per 60 gallons I should be fine right?

I tests CA after putting in 7.5 grams last night and it said my CA was 360. Today I dosed another 7.5 grams and tested again and it now says 340. Any suggestions?

Don't forget that it's the actual amount of water in your tank that you should dose, so allow for rock and sand displacement, and don't forget to add however much is in your sump.

I dose it at 2 tsp/gallon of topoff water which I then dose at the rate of about 1 gallon a day.....my ca is running at about 420..... if you don't have a lot of hard corals or clams a ca level of 360-380 isn't that bad.....just watch that you alk is steady too...

Alright, thanks. My alk is now steady at about 10. I'll test again then add more buffer if needed.
