I have 2 different Aqueon 36” led optibright bars attached under 2 different shelves. When I first plugged them in they were in sync with 1 remote and I was delighted. But something happened and now one light bar will not respond with the remote. I can only plug it in or unplug it for on / off and no ability to change lighting. I don’t want a programmed lighting for the tanks. I prefer manually adjusting intensity and color but now I can’t do the same with both lights. Is it a light problem or a remote problem? Help get them synced again
