LEDs for a low tech
I'm in the process of planning my 55 gallon low tech tank (no CO2 and minimal to no ferts) and am looking for recommendations on which led lighting fixture to purchase.
The tank is 48" L, 20" H, and 12" W. There will be about 2-3 inches of substrate down. I'm planning on initially having some floating plants (either duckweed or watersprites) and then pulling these once the other plants establish themselves. The tank will be in a corner of a room without direct sunlight. I will be running 2 4-5 hour light cycles each day. I'm hoping this will allow me to lean more towards a mid to high lighting arrangement.
I'm considering the marineland double bright or something from the finnex line. I'm not sure if the marineland is sufficient for 20" of depth though. I do like the finnex fugeray ultraslim and the ultraslim II. The II might be over the top though.
What led light set ups have you run successfully? What are the upper limits of lighting do you feel are capable with a low-tech tank?
