I have 110 vho super actinic & actinic whites (4 bulbs total 2 each) that are 2 yrs old and I want to replace with the same bulbs but I am concerned about the intensity of the new bulbs creating an algea bloom. I currently have no problems and do not want to create any but I most change the bulbs due to the age of them. Can anyone tell me the best way to replace these without causing a bloom or any other disruption?
