So, I'm trying to grow rotala in my divided 10 gallon. I originally bought a cheap 24 watt led, but my rotala is very spindly and suffering a little, combined with the fact that giant duckweed is taking over the tank and reducing the lighting even more is making me realize I'm going to need a good deal more light for this tank to be how I want it. I'm looking for some budget high lighting for this tank that will penetrate through some duckweed and help my rotala get a little bushier. I had really hoped to spend less then $40 as I'm on a very tight budget. Does anyone know of any good, cheap lighting options that will fit on my 10 gal and not take up too much space and help my rotala bush out a bit?
