Calcium reactor question

[briantson]

I am in the market for a calcium reactor. I have been reading up on lifereef LCR1/LCR2 and Precision Marine CR622. I am wondering if anyone here that have used either one of these reactor and give me some good/bad feedback.
thanks

I have a knop on my 200g and a koralin on my 75g, I can tell you for sure that the koralin is much easier to use and setup. Good Luck
