Thanks.
Im sure I could get this info from reading a bit more but I will ask anyways....
Do I need to use the ProfiLux conroller to use the GHL 3 pump stand alone dosing station?
The reason I ask, is because I do not want to have to change my controller right now. Although if I could go back I would have bought a Profilux instead of Neptune

The ones I have seen people using are awesome!
I am still just trying to get my head around the Balling method but I really like the concept.
EDIT: Ok, read some more

Certainly something I want to do and it looks like the dosing pump has a built in controller?
I LOVE how easy this makes things...I can see why this method is so popular in Europe. I was about to buy a Ca reactor and I am now very glad I did not.
