Calcium and Alk readings

[jtwilson]

Ok this afternoon my readings are as follows:
Calcium 390 ppm
Alk 8.6 dKH or 3.09 meq/L
is this ok or what? Is it correct that if I drip some calcium that my alk will lower and vice versa?

Your reding shold be alk 9 to 12dkh and to rais it up just use a ph buffer it will take care of the Alk

 

[jtwilson]

well ive got a product by Seachem called Reef Carbonate....this should be ok to use right? It says it raises carbonate/Alk.
also if I do raise my alk to around 9-12 dKH will this lower my calcium? I don't want to do that cause my calcium is only at 390 ppm. What should i do?

if this isn't a reef, i woudn't worry about it. what's your pH?

How often are water changes? Please give all water info. Reef?

Oh yeah its a reef!
125 gal
with 55 gal sump/fuge
nitrate 0
Phosphate 0
Nitrite 0
Calcium 390 ppm
Alk 8.6 dKH
salinity 1.025
I'm sorry i did not test ph today

https://forums.saltwaterfish.com/t/175205/calcium-alkalinity-chart You are pretty close to "balanced" . 8.4 and 420 would be balanced.

I am really interested in this thread as well. My readings are 7.7 dKH and 370ppm. I would like to know how to raise both as well!!
That ALK/Calcium chart means absolutely nothing to me!! I'm not sure how to read that chart...
