The glass tank kits would not be built to order. We would simply bring a couple container loads of popular sizes and option them with the innards. As I posted earlier, most of the well-known Chinese glass tanks are made by one company. Bringing these in flat saves big bucks. One problem is the cost of a container has gotten crazy high. Fact: the cost of the containers got so high that a fully laden ship sailing from China to the West Coast generated enough profit to pay for the ship! It's like buying a car and paying for it with one Uber ride.
Well dang. Sounds like we should all be building ships instead of messing around with this reef stuff
