Difference between GHL SA or Profilux

[Jakepen]

What's the difference beteeen the two?

I presume you're referring to the dosers? In which case the SA is a standalone unit whereas the other is a unit that requires a ProfiLux controller.

SA stands for "Stand Alone" and refers to the Dosers.
There are two versions, the standard Doser which requires the Profilux (the GHL aquarium controller) because the this doser doesn't have it's own brain.
And the "SA" Doser which can be used by itself, no controller required.

Okay, thank you both so much for clarification. I think I'll be ordering one at the end of week. Assuming I can find the right one in stock...
