So now it begins... since I broke down my last reef tank (300 gallons) at home, we´ve had a little tank in the office. Of course, that has never been taken care of well. When that tank was worn out, I installed a tank in the production area just to keep everything alive for roughly 8 weeks, until the new install was planned. Now, 2+ years later, the production tank is slightly in the way and I wanted to fall back in love with my hobby - that´s why I decided to put a new tank into my personal office, right in front of my desk. Since my office is quite limited in space, I could only go with a max width of 1.8meters, and the standard tanks are 1.6m, so that´s where I´m at now. I didn´t want to pay for any customer specific size, since it´s "just an office tank". I rather spend this on equipment... After having loads of discussions about lighting and since I´ve always been a HQI/T5 fan, I sacrificed the metal halide because of environmental issues (energy), but went with a T5/LED hybrid. The T5s give me a good spectrum and basically enough light for everything, while the LED can be tuned for optical impression and effects. Specs: Giesemann tank with black side and back, optiwhite (starfire) glass Giesemann Aurora 1.5m ( both in customer specific coloring, Irridium/orange just happens to match the Abyzz color) I had the luck to be able to have a freshwater connection installed in the cabinet as well as a sewage connection - makes water changes in the sump easy.
