Ordered a 130.4 this weekend - can't wait! Looks like VCA has released a Waterbox adapter so that their Random Flow Generator nozzle can be used: https://vividcreativeaquatics.com/shop/22mm-waterbox-aquarium-modular-hose-to-1-2in-rfg-adapter/
May be a good alternative to the Spinstream assuming it works for the 10 cube.
Great-looking scape!!7226 Build. https://www.reef2reef.com/index.php?threads/Waterbox-7226-Build.563472/.
Been going 8-9 months now. I truly love this tank! @Waterbox Aquariums, you guys rock!
