So the difference between the Z5 and the Z6 is "The Z-6 also utilizes a non-controllable DC circulation pump for reduced operating noise and energy consumption". I have a reefer 250 I really think I only need the Z-5 or Z-6. My nutrients have been very well controlled since the initial cycle, my parameters where .1 phosphate and 15 nitrate, and I just started up the Fuge after that. Off course I still have a few fish I'm planning on adding, and some off my fish are pretty small still. I can't imagine i'll need more than the Z5orZ6 but I'm considering getting the Z-7 or Z-8 mostly only because it looks like the Cup is bigger, so less emptying.
Any thoughts on the differences and any opinions from anyone who owns this skimmer?
