gets used up very quickly and I have to dose one part of a two part to buffer my Alk
to 9.5 dkh
. Before I buffered my Alk
up from 6.5 dkh
my corals didn't seem to be able to use the calcium up and my calcium was around 5-550.
Here's a good link about salt mixes

Here's a thread I started in January when I was having similar problems.
Alkalininity and Calcium
It should be said that since this thread I switched to an Elos test kit for Calcium and for the first 30 days I tested for Alk
every day switching to every other day for the last two weeks and I now test for Calcium twice a week. I've logged all these numbers and found that with my dosing every other day I have stabalized all my numbers. I also bought a pinpoint Ph monitor imo
the only way to test for Ph. I record my Ph every time I test for Alk
. I also test Ph once a week with Elos to double check my Pinpont. I know this seems like a lot of testing and it's been more expensive than I wanted burning through test kits, but once I get it figured out I'll cut back my testing to once a week or if someting looks out of order. On a side note I'm going to start switching salts this week. I've talked to some reefers who swear by the Tunze reef pro salt.
