I just had one of my Actinic light bulbs break and I don't have the money to replace it till the 25th. Will my tank be ok with just one bulb till then? P.S. There are still 2 10k and one actinic bulb working.
Technically you don't need actinics on your tank, its just for human pleasing color to the eye. No you don't need to replace it right away, you'll be fine with what you have in the mean time.
