With my aquarium lighting i have a trip[le buld florescent lichting unit that has 2 white and 1 blue tube in, i never use the blue , as a secondary unit i have a 15" blue led unit which give the aquarium a stunning look when its on. Both units are on timers
The Blue comes on @ 8am until 10am and the other unit comes on @ 9.30am woth the 30min overlap
The second times on it are the blue unit comes on @10pm and the other unit turns of @ 11pm
This is giving the fish a day/night cycle that does not alter except for daylight savings in uk.
Is this a good idea and a healthy practice for the fish? They do seem to calm down and look for somewhere to settle for the night when the blue comes on and the other unit goes off. And slowly start to get more active in the morning when the blue comes on again after night time darkness
Hopefully it is good practice?
