In Robert M. Fenner's The Conscientious Marine Aquarist
, he states on page 54 that:
"... For all types of flourescents, there are now electronic ballasts on the market that aquarists all ought to use... You can also set them up on dimmer controls to simulate dawn and twilight..."
WHERE? lol. I have never seen a setup like this. Anyone have an idea what he is talking about? I would LOVE to get one where each individual tube is set to come on at a certain time of the day! HELP!! PLEASE!! lol Thanks All
