How do i increase Ca but not Alk?

[Snowgrrl83]

My pH ranges between 7.8 and 8.2. My alk is on the mid-high end (11 dKH) and my calcium is low 350. I have bio-calcium supplement (but it is balanced with alk additive) and i use regular instant ocean salt. How can i increase my calcium without increasing the alk?

Any dosing product to recommend and how?

Ps- this is an 18 gallon nano

*PH.

use Calcium chloride. you can get it in powder, and mix with RO/DI water, you can also use the "calcium part" of the 2 part sold in LFS. like B-ionic, Kent CB or ...

Calculator for measuring how much to add. use half the dosage, test and then use other half hours later. it may alter PH.

Sounds good... Will try it cautiously.
