(roughly 9 drops). My ph is on the low aside between 7.8-8.0. I eventually want to get corals but was wondering if I should straighten my levels out alittle more. Should I raise KH
and ph in order to lower calcium slightly or are these numbers good?
First off, the norm on this site for Alkalanity levels is dKH
, rather than ppm
. So your 9 dKH
is OK. High Calcium wont cause any adverse effect on corals, so don't sweat that either. You pH is a bit low, but as long as its stable, you should be fine. That being said, dosing a bit of Alk
+ won't hurt either. But the only way it lowers calcium levels is thru Calcium Carbonate precipitate, not really an advantage to intentionally do that.
Once you start adding corals, you'll likely find the levels starting to drop, and as the coral densities increase you MAY need to start dosing. Personally, I wouldn't really start dosing yet, based on your levels.
