kalk or 2part

[marke]

Just bot a drews doser and some other stuff from you. I was going to dose Kalk along with my CA reactor. However in reading I am wondering if 2part is better. I have a 240 gal tank, ie150gal water, high sps demand and the reactor cant keep up. Your advice is appreciated.

Either is good .

Kalk is easy because it just goes in your auto top off water. Probably the least expensive as well.

2 part is good because it is really accurate .
