I have a bank of 6 t5s over my 200 litre reef tank.
4 of them are a marine reef white type tube with 2 being a marine blue tube.
These are at the stage where I need to change 2 tubes a month for a period of three months.
Now I believe the reef white tubes are the more beneficial for the corals so to my question.
Do the blues have to be changed as frequently as the whites as I am thinking the blues dont add that much beneficially to the tank apart from aesthetics ....... or am I wrong.
