Thanks to the generosity of @noopsyche I received my K7 Pro II today. This is the first time I have ever gotten a package on time from DHL shipping let alone two days early! Anyway, I am going to post pics of the unboxing and first impressions. I will test this, at first, on my 18x18x11 nano then on my 30x30x24 main display that will have the rock structure concentrated in the back left 20x20 area. So it will be tested on two different sized tanks and depths and with totally different corals in each. (I wish I could afford a second to run both tanks at once but it's not in the cards at the moment) So I have to, again, say Thanks @noopsyche !!!
