T5 tube replacement time and type
I'm coming up to six months on my current light fixture (Aquatic Life T5) and was wondering about when and what to replace the tubes with. I recently read an article that said that most t5's lose some effectiveness over the first 3 or 4 months but then keep that level for the next year+. Just wondering what the consensus is? Also I guess even though you switch brands you have to keep the wattage the same? Should you replace all whites and blues or whites then blues a month later? Any other hints...
