I have the Current USA Orbit IRC Loop 72inch for my 120 gallons, and having a hard time figuring out how to do the timing; I know the feed and the pumps, etc., but when I put sunrise at 8 am, and if you select daylight does not give a choice for time length, and sunset at 8 PM and never goes to that it seems. I have moonlight set for one hour. Also, another issue when I leave, of course, won't work. It's Bluetooth, and after return to the house, it will take a couple of mins and reconnect, but I sometimes find myself that it does not work; I have to remove the app and install and add it again; I had to deo that several times too, other than that I love the product, I also have Current USA Eflux that works with the app, any help appreciated AS the Current USA has no instructions on how to use the app.
