I have an apex and tunze pumps+nano wavebox on my 120. I recommend using tunze controllers for the flow pumps and the apex for everything else. It just simplifies everything. There's a big push by the "neptune geeks" to use the apex for absolutely everything and I think this complicates things. Apex is great for lights, temp management,pH/orp and electrical control plus it's web based and gets your system on line. Hope that helps.
