I have tried both, IMHO on a larger system with fair amount of sps and lps will highly benefit from a calcium reactor. If your system is under a hundred gallons or less then dosing might just work for you. It all depends on what suit you better.

Over the last 7 months or so, ever since I switched over to a vertex calcium reactor I haven't messed around with it for more then a few hours and that's including setting it up. Ph probe and solenoid control is a must if you are setting one up, besides filling the media and the co2 which I haven't done yet the unit has been rock solid(knock on wood) compare to when I was dosing, I was using 1 gallon jugs of bulk reef supply chemicals which cost me a arm and a leg just for shipping. I would have to fill the jug up every week or less. I know some can argue why not just get some bulk from around town and use some larger containers so the refill intervals are shortened but for the quality of their bulk chemical product, you just can't beat BRS and until you start mixing chemical yourself, it is just a pain in the where the sun don't shine. I personally hated doing it. I had 6 jugs in rotatio and it still ****ed me off. Some days when I am shaking the alkalinity bottom and the rest just won't mix, it always brought me back to a childhood story of me shaking a Costco size salsa in the kitchen and the lid flew off, needless to say my mom was not impressed with me.�� One thing dosing seem to have an edge over calcium reactor is the ability to fine tune your parameter, as long as you make sure your salinity is in check then it's all good.

The choices is really entirely up to you. Both system has pros and cons. It's just in a larger system, a calcium reactor seem to have more pros then cons over dosing but you still need to purchase a decent reactor so you don't have to mess around with it too much. Same goes for dosing. If you are going that route, make sure you purchase a good dosing unit like a liter meter or the profilux stand alone unit for accuracy and reliability. One thing I have learns from this hobby is if you are dedicated reefer and are willing to do it right, spend the money and buy some decent equipment cause if you don't you will regret it later.

I hope this helped, let me know if you have anymore questions about the 2, I will be happy to help you out.
