Guys this K2R Calcium Reactor that you can check here > LINK (http://www.aquacave.com/detail.aspx?ID=708) <
does it work without any CO2 addition like normal Reactors or I am wrong?

Are these any good for really mantaining Calcium and ALK and does anyone here have this reactor or similar?

It requires CO2. The CO2 is needed to drop the water's pH to the 6.1-7.0 range which will dissolve argonite.

So it works like normal reactors. I thought that because only this model there isn't mentioned that you need CO2 addition with it.

Guys, I never had a Calcium Reactor and need some info please.

I wish to know which one is best to buy and not too expensive for my 180gallon tank ?

Both the Geo and the Korralin are well regarded. What size exactly really depends on your calcium and alk depletion. To save money, buy a 10lb CO2 bottle locally though, it doesn't make sense to ship such a heavy item.
