I have a 300 gallon glass cages peninsula in my basement but given all the time I have been spending at home I started thinking about a tank in my home office. Recently have come to the realization that I will never be going back to working in my office building 5 days a week. So I pulled the trigger on a used rimless Cadlights 100 gallon with a black lacquer piano finish stand. Tank was in great shape and stand had a few chunks missing. Sump was not included but I already had a spare trigger crystal sump in the attic. I decided to toss the metric plumbing and start over with english fittings. I have already spent more $ on plumbing than I paid for the tank. First thing was to drill out the existing holes with a 1" and 1.75" diamond bit. Already had these sizes in the tool box.
