Hi, Could I get some feedback on my setup? I don't have much space so I decided to put the screen in my wet/dry sump where my bio-balls were. The lamp is within 4 inches but angled. I ordered a plant growth bulb but the one I received didn't work so for the meantime I put a regular 40 Watt tungsten bulb. The light is however shining through the wall of the sump and I'm not sure if this is a good idea. Maybe algae will start to grow on the sump walls or the skimmer beside it? Thanks for the help.
