Hi Dick,
Still interested in talking indoor lighting? I've been having very poor luck getting any interest on the subject elsewhere.
On my indoor pond are four 40 watt lamps. I normaly use two 6500K and two aquarium/plant lamps, but have been using four of the 6500K's for the past six months or so.
My fish are inside year round presently.
Do you have your lights on a fixed timer?
Mine are on 12 hours a day, but I've been considering switching them to staying on only during daylight hours so that the photoperiod changes with the seasons.
Do you think this would be worthwhile?
Thanks
Dan
