Confused with lighting situation
I have a 20gal tank...not an extra high or long. the hood is an eclipse 2 with 2 bulbs (18inches) that came with the hood T8-15Watts. I changed one bulb to a Plant and Aquarium (by Philips) 15Watt with 410 Lumens with a color temp of 2700K. The other bulb is a Natural Sunshine (by Philips) 15Watt with 590 Lumens and color temp of 5000K and color rending of 92.
My substrate is fluorite. i have anacharis, anubias nana, and a microsword.
Is my lighting sufficient? also if not...where do i find a local retailer that sells a higher wattage bulb.
my other question is when 6500 Kelvin is recommended...is it per bulb or combined?
Thanks for your help
