I'd personally stop with any chemical adds aside from your dechlorinator. Tidals are nice filters. I've had a 110 running on my 75gal for years. I don't care for the look of it in the tank (pump/motor housing), but the thing works as well as a HOB can.
In terms of lighting, any of those LED flood lights could work, regardless of color/temp. Get what looks good for your setup.
