The title of the thread says it all. I am not going to bash Neptune systems, all I am going to say mine crashed again, and the word fluke in the technical response left me going I cannot take any more chances. This was my second hard crash of the system, where both time the system came up in an inconsistent state and caused issues. What I currently Have: Apex 2016 FMM (Fluid Monitor) WAV Controller (Went back to my Vortech) Additional PM1 and PM2 Module used to Monitor Reactors LSM Module (Lunar simulation) Leak Detector Multiple EB832/EB8 ASM Module Multiple Displays What I have Ordered: ProFilux 4 Ultimate Set PLM-PH-Redox and PH probes * 2 2 Level Sensors (ATO) 3 Power Bar 5.1 Expansion Box Proflux Touch (Downstairs Sump Display) Vortech Controller Mitras Simu-Stick Mitras Simu-Driver Temperature-Sensor 5000 l/h Flow-sensor 9000 l/h flow sensor * 2 Assortment of PAB Cables to connect everything PL-LY cables to Connect Not ordered yet: Leak Detectors New ¼ Relays (I use these as safety I may see if I can re-wire the apex ones or try) And what the solution will be for PAR readings as I have a ASM module (idea’s welcomed as I may also swap out my CebruSun T5 with Mitras LED) My plan is to post the actual switching out of the components, and how I converted the programming from my Apex to GHL. Join the discussion, have some fun asking questions or answering some of mine, and I will attempt to show as much as possible!!
