Hi, I'm new to the Apex scene and just recently bought a used classic. I'm trying to figure out which route I should take on my new 36 cube I just setup. I will use either 2 powerheads or 1 gyre pump. If I go the powerheads and go with tunze do I need the VDM module or is the connector of the main Apex module what I will use? Also if I go w the tunze, I read somewhere that the newer tunze pumps run at a different control voltage and you won't get the same granularity in control as compared to the older models. Is this true? I also thought the gyre pumps were Apex ready, but it looks like you need the ice cap module as well. Is this correct? Any help would be appreciated.
