If you don't have a calcium reactor then definately 2 part dosing is the way to go....
Look at it this way a CA set up with good reg's monitor and so on new will go for about 750-800 bucks.
2 part is 30 is per and if used gently like 2 caps of each per week will last you 5-6 months so how long would the 2 part or shall I say how many till you displace the cost of a CA set up..... Also buying bags of CA and mg can cost alot from the lfs like around 30-50 for the year.
The downside of CR is dialing it in keeping it monitored so it doesn't plug up the tube (if you run fine calcium) and run the pump dry. Also keeping CA levels in check.
Downside to 2 part have to dose once a week in top off water however I'm doing both so double the work for me.
