Hi, I'm selling my Profilux 3 EX , for $1,300 firm. it has the following probes,temperature,redox,conductivity, PH and a 6 outlet digital power bar. Also in the price is included a GHL slave doser, 4 pumps ,the entire system is about 5 months old, I'm selling it because I sold the tank but the new owner has no idea how to operate this, and is not interested. I got the entire system from progressive reef. If you want to verify is only about 5 months old. I posted it here first instead of the "buy & sell" since here is the GHL users, and want it to give you guys the "first hands" on this opportunity to own a " badass" system. Thank you for looking.
