I'm used to having live plants in my tank but my old tank set up had a full spectrum fluorescent tube light- my plants grew like crazy and I loved it! My new 55 gallon is plant less ( none survived the transfer I believed due to some water quality problems that are now resolved) I'd like to replant but it dawned on me that my new lighting system might not support proper plant health. Unfortunately I can't tell you much about the lights themselves because it came in a kit and nothing is specified about their strength or anything. All I know about them is that there are white and blue ones during the day and I can switch them to just blue or off at night. Also can changing the light type stress out fish or don't they seem to care?
