I guess you bought this apex used. Neptune would never sells you an apex gold looking like that. Go back to the seller and kick his/her behind for lying to you. You
either have 2 PH probes or 1 PH and 1 ORP probe. I can't tell from the picture you posted but the Salinity probe does not plug into the Apex base like what you have in your picture. And from the back of the probe, 1 of them is not even a Neptune probe....Man hate those sc!m bags taking advantages of the rookies.
Worse it looks like you PH probe is out of the water for a while. If you ask [MENTION=7875]SanClementeEric[/MENTION], he would have said the PH probe is tossed! [MENTION=11086]theMerchant[/MENTION], the apex guru, would have been able to confirm what you have is not an apex gold!
Having said that your apex is value at $300! I hope you didn't pay dearly for it....! GLWS
Temp, PH and Salinity.
