Elder 1925,
Great project and good luck. Great respect to your education to the community. Manufacturers need disruption. As a circuit designer and a long term owner of a 180gal reef tank in one's home, I must caution you to please be very careful with your shared photographs. Essentially, you just gave a roadmap to Chinese organizations to produce cheap and faulty copies of Apex's fine work. It is understood that this not your intention and one applauds your efforts to make things better.
The aquarist industry is increasing becoming fragmented with respect to a controlled look at one's reef passion. It reminds this old author of the quad audio standards fight in the early 80's. Everyone lost.
GHL, Apex, Reeflink, and quite a few others either pioneered or entered the market to help us out and are doing fantastic things competing with one another. Whom one chooses remains a personal choice. With respect to fragmentation, please look at what has occurred over the past few years with respect to lighting control. Geismann, AI/Ecotech, GHL, Maxspect, you name it, no longer talks on a common interface. It is frustrating that after years of confidence that one no longer has a common interface to access to ensure that one's passion tank is doing okay when one travels Internationally. It is very painful now.
Keep doing what you are doing Elder 1925 Sir. This is how the industry grows.
Terrance, you should follow and learn from Elder 1925's efforts. Further, please continue to push a standards efforts with your competitors.
Respectfully Submitted,
Drukyulgoods
