Calcium issues!

[MizTanks]

Where is my calcium going? I just tested and my calcium is reading 320/340
I doesed with Kent CB parts A&B everyday for a week at 2ml part A and 3ml part B. Ya think it'd be higher with the dosing right? I've had this low calcium issues ever since setting up my tank. Never have been able to get it above 400, let alone stay there. I'm not keeping any sps/lps so how worried should I be about the low levels. I do have snails and a shrimp though. I use RO/DI water, and Reef Crystals.

I wouldn't be too worried. You took a big bite with such a small tank for a first (and congrats on doing this well).

How much evap do you get each day?? Do you have to top off daily like I did with my 10 gallon??

If so I could walk you through setting up a drip type top off with Kalk that may help.

why are you not dosing equal amounts? is something out of wack to start?

[jojo22]

Speed, I don't remember if it was the same stuff but I had a Kent product for nano reefs, and the directions said to dose more of one than the other, the instructions always worked well for me. So it may just be the product.

I never top off! No need, no evap. I do WC every fri, 2+g. I just tested my new water and it reads: ph 8.4 cal= 460 and sg=1.030 it's a little higher cause I'm trying to raise it from 1.023 to 1.025
However all these readings change once the water gets into the tank. I was dosing cause of the low cal, it was suggested to me that I do it less of A then B. I'm not totally edu on the chemestry part of water as of yet.
I do got to say though, that my tank is doing great! No losses of corals (all softies) all other water parameters are right on, Kh is 12, 0 nitrites, 0 nitrates, 0 ammonia, and 0 phos ph has always been around 8.4 and my fishes are happy!!

You've been dosing more of the alk this whole time. You'll need to switch and dose more A and less B. Once you have your Ca/alk balanced you may be able to meet your tank's demands with water changes alone. Since you don't have high demand organisms and you're changing (what I'm assuming to be) a good percentage of your total volume each week.
