Recorded the minutes of the QGM
Estimated how much activated charcoal pellets we might want in the laser filtration system, found a reasonably priced listing on Amazon, and ordered 5 litres, which should be enough for about 6mm depth across all six trays. If this works well we can order a larger quantity next time. It’s consumable so we’ll want to pay attention to the exhaust smell. Our filtration system was always intended to use activated charcoal but for whatever reason there hasn’t been any in there for a long time. Maybe it constrained the flow too much?
