Calcium reactor vs Dosing or other options

I've never used a Calcium reactor but have purchased one just haven't set it up yet. I've always done manual dosing and a couple water changes a year. Once I figure out the calcium reactor I hope it will make things easier then the manual dosing.

Tank size: Currently only a 210 and a 65 Red Sea Max

Tank type (all natural, high tech, white sticks or algae covered, etc..):Currently sticks and algae covered

Coral types kept (SPS, LPS, sofies, low end, high end, etc..): currently mostly low end, softies and LPS

Years in the hobby: 6 years

Tank type (all natural, high tech, white sticks or algae covered, etc..): High Tech

Coral types kept (SPS, LPS, sofies, low end, high end, etc..): Mixed Reef, SPS, LPS, Softies

Years in the hobby: 4.5

I was always manually dosing my tank with decent results. But I was always a little worried of over dosing. I heard numerous stories about how a calcium reactor is much more stable and provides more nutrients than manual dosing, as well as cheaper in the long run. 

Manual Dosing 

Pros

No expensive start up cost.

Cons

Dosing on a daily/weekly basis

Difficult to dose smaller elements (Strontium, Potassium, etc...)

Costly month to month basis. 

Calcium Reactor

Pros

Provides a more stable dosing method (Continuously dosing in small amounts)

Doses small elements not often found in manual dosing.

Little to no cost after initial purchase

After dialing in little to no maintenance required

Cons

Can lower PH drastically if no fail safe (Apex)

Expensive start up cost

Bulky equipment in sump or out of sump

I must say after I dialed in my reactor i saw increased growth, color, and polyp extension. Nothing is better at building corals, then corals themselves. What I mean by this is, that the media inside the reactor is essentially dead coral, with calcium, alkalinity, magnesium, strontium, potassium, etc etc... IMO this created the most ideal setting for coral growth and development.
