i have a gently used apex. I just pulled the plastic off the display when cleaning it so the screen looks brand new. This was used on my frag tank and I took it down. This system comes with the display, Brain, 2 eb8s, pm2 no salinity probe, 2 ph probes, 2 temp probes, and many bus cables and power cord. This was well taken care of. I will not part out. I only ship to the USA. Askingprice is 550$ shipped.
