So I found out today that my fixture is a zoo med t8 fixture with reflector. I've been using it for about 5 months with a 10.0 t5 bulb inside the t8 fixture. So my question is, should I get the t5 fixture for my t5 bulb, or can I leave it as is with the t8 fixture? She doesn't have mbd or anything and looks healthy, although she is lethargic still.... So what should I do leave it or buy a t5 fixture?
