If you were going to replace a T10 48" bulb with a new one..which would you choose over a mixed young reef tank?
I currently have an old fixture I used for my 55gal freshwater. It has a Marineland F40T10 48" natural daylight bulb in it. Sense I'm patiently awaiting on the IRS.........I am using this to supplement my young reef tank running one 120w Chinese black box LED
unit until I buy new lights or get the broken one fixed.
I've had this above the tank now for about 5 days and the corals are doing well. Much better then they were with one LED
unit. My tank is 5ft long and 2 feet deep. Would you keep this bulb in and just wait out the storm? Or would you replace it with a different one? Keep in mind I don't know how old this bulb is either.
I really welcome your thoughts. Thanks!
