I won't discuss the pro/ cons of other controllers as I have no experience with them. About 6 years ago I decided to go with the Proflux Controller. Pricey, even back then, I know. But after looking at other systems I'll explain my decision. Ghl, the company that makes the Profilux is a German company. Their focus was/is to make a reliable unit and I would have to say it is. But what I liked most was the fact that the controller is
upgradeable. At the time, other companies had units available that were 2nd or 3rd gen but new designs over previous versions that left current owners with the choice of keeping what they had or having to buy the new unit. So even if it is a larger upfront cost I knew I wouldn't be left with an outdated controller.
The
design was very compact. All the different modules just slide into the mother board and can be done buy most.
Multiple probes for temp., ORP, salinity, ph, etc. And since I purchased my unit they have also offered an
expansion box that can be connected using telephone like cable. Allowing tanks in different rooms on different floors to all be monitored and controlled by the Profilux. Remote
Touch screen control is also now available too. Dosing units - I have two in separate areas for two different systems. Co2 control. Light control. Level control. Top-off and water change features. And
free software to change or adjust anything the system does.
Now I will admit the programming can be taxing, but I'm no programmer either ! Their online support and forums are great with many helpful folks there.
Matthias, the owner of Ghl has always been open to suggestions from end users.
Aqua Illumination and Ecotech integration to mention a few. Constant software and firmware upgrades. And what ever he releases has been thoroughly test before released. Those Germans LOL !:biggrin: Again, I know it was a little pricey but I though well worth it in the long run! God luck, Neil.
