fluorescent light tubes replacement

[sdergar]

I have an Aquatic Life fixture that's coming up to 6 months of service. I love the unit with it's functions, timer look, etc. There are white 10 000k and 460/420 blues as well as moon LED's. As for replacing the tubes how often should this be done? Are there better replacement tubes or are the OEM's the best to go with? Can you change whites and blues at the same time or should you space that out? Maybe even space out the replacement of each of the blues/whites (ie: replace one of each colour at a time instead of all of the same colour?).

Thanks...Steve

The only thing I could tell you for sure is that ATI and Giessman are bulbs you should look at getting, very high quality bulbs
