Calcium Reactor - Please explain

[HaleMoana]

OK, I'm new to the hobby and I don't fully understand the role of a Calcium Reactor.
I have an opportunity to purchase a lightly used Calcium Reactor from a local reefer who is breaking down his tank.

I understand these offer low maintenance instead of daily supplimenting, but what are the other pros/cons of using a Calcium Reactor? I'm seriously considering this purchase. With my tank only being 75 gallons, this is rated for a much larger system than mine... will that pose a problem.

I might not need it now, but might be nice to have down the road? I guess I am just looking for pros/cons.
I travel from time to time on business and wonder if this will aleviate some headaches while I am away. thoughts?

thanks!

Saltwater is sucked or pumped into the main chamber where carbon dioxide is added. Mixed together it creates carbonic acid. The carbonic acid flows down through the crushed coral and dissolves it into your tank water. Once set to your tank size it will maintain your calcium and alkalinity.

Depending on how the reactor is designed, it may not have any cons. The key to the ease of use and convenience is the relationship between the CO2 bubble rate and the effluent drip rate. One of the biggest risks is adding excess CO2 to your aquarium water and crashing the pH. The typical bubble rate can be as low as 6 to 10 bubbles per minute with an effluent drip rate of of 40 to 60 drops per minute. I do well with a reactor on my 50 gallon aquarium and enjoy not having to dose every day. See if the seller has the manual for the reactor and read it. If you would like any more help, feel free to e-mail me. Hope this helps.
