Thoughts on a calcium reactor?

Would any of you guys recommend one? Like i recently posted i am starting a 120g reef build.
I am debating on if i should get one or not.

I just hate the fact that you need a Co2 tank hooked up to it.
Is that really needed? i feel that your tank would produce enough Co2 on its own to not need and extra Co2 tank.
Ive never really considered these before so i dont know too much about them.

Any Input?

 

I'm in the same boat..

 

CO2 is essential and doses your reactor, not your tank. It drops the pH in the reactor, which in turn reacts with the media and there's your calcium.

 

It sucks! lol If they were alittle cheaper and were explained better in all the articals i have read i would just buy one..
There just so damn expensive.

I heard you can build them yourself for alot cheaper but i cannot find any build plans for one online!

 

I bought my whole calcium reactor setup, used, from a local reef forum. Paid $250 and worth every penny. It is so nice not dosing every night and morning. I was using 40 ml. of cal and alk (BRS 2 part) a day. Now my parameters stay stable and everything is thriving. If you are having problems keeping levels consistent, I highly suggest it. Look on Craigslist or local classifieds.

 

This article helped me set up mine. Not sure if it will confuse you more but there is great information in here...

Yeah i could get them locally for about 300 bucks new, but i havent started my tank setup yet. but maybe i will invest in one. and that article is basically what i have been looking for! so thank you!
