Hi,

I am looking for info on the best and most economical solution/source for lighting for a 20 gallon freshwater tank. I inherited from my late husband and think the light may need replacing soon (old Coralife with actinic bulbs--one blue and one white compact flur.). It is on a timer now. There is natural sun in the room too. Timer runs about 9-10 hours a day. I am new to fishkeeping but learning.
