LCR-1 Calcium reactor

[snipertwobe]

just picked up a Lifereef Calcuim Reactor LCR-1 for a price i couldn't refuse with co2 tank and solenoid valve. it is supposedly a good unit from what i have read(very limitied) does any one here have any experance with these units? good or bad i'd like to hear about.

I also need to get ph controller to power the solenoid anyone have any preferances there?

thanks in advance
