Morning. I have 75g mixed reef, lightly stocked. I would like to have the option of adding KH director at some point but I am unsure of which Profilux set to buy. Money is an issue so I don't want to get top end straight away if possible. Also, I already own a Kamoer Wifi doser, is this compatible with the GHL controllers or do I need a GHL one?

Many thanks, any other advice is appreciated.

Steve
