How are my levels?

[Kmsutows]

I've finally purchased a good test kit and am at a loss on how much Ca (reef foundation A [Ca/Sr/Ba])

My levels with the RedSea kit are;
Alk 7.5dKH
Ca 370 (at start of color change)- 390 (at end of color change) which do I go by??
Mag 1340(at start of color change)- 390 (at end of color change) again, which do I go by??

Your alk looks good although some ppl prefer it a bit higher, close to 8 or a bit over.
CAL, you go by the first color change when it turns blue.
Same as with the MAG

You might dose Cal to a level of 400, as your not far off.

Thanks for the reply! How do I dosend the Calcium it seems like quite a bit from bulkreefsupply calculator... it says 143ml.. I have a 150gal with sump minus rock so guessed 140gal. In August I bought a Reef foundation A [Ca/Sr/Ba] that I wanted to use. My question is do I really add 143ml and. An that be done at one time? Do I need something to balance it? Thanks again
