Not knew to fish but have upgraded to a new Biorb halo tank - am a little confused with the lighting! I have what I thought was the LED moonlight, but according to booklet there should be a lever switch on inside of lid to move between the different settings, which I don't have - so I have been told I have the standard lighting and should just be one switch (on the wire) to switch on (white light) and off... But I do have LED moonlight because it's on now.. But when I switch the light on it flashes 3 times white - then goes blue. I have no idea how to change lights as there's no lever. Sorry if this is confusing.
