WPG queastion (Setting up a tank today)
I bought 4 Florescent Daylight 6500k 100/23 Watt bulbs yesterday.
They are equal to a 100W bulb, but only use 23? How many
Watts per gallon would I actually get if I use all 4? or just 3?
I make my own "fixtures" and they have worked well before, but
want to know for how many bulbs i should make it.
I want to run a "mid" tech tank? Haha.
Mostly want to plant Rotalas, hygros, some Hairgrass
maybe, Vals, bacopa's.
Would those bulbs be enough? Or maybe too much?
I am going to use a 20L.
Thanks in advance.
