Hello. Found I can grow plants requiring moderate to bright light in low light conditions. This is one of my 55 Gs. Has only one 32 watt T8, 6500 K
bulb from Lowe's, packs of three cost $10.00. Dose three different liquid ferts two to three times per week at night when the tank lights are out. Found the ferts work better.
Have varieties of Cryptocoryne, Amazon sword, Penny wort, Water wisteria, Java fern, Indian fern (floated), Ludwidgia repens, Peace lily, Singapore moss and a couple of others.
Started using plastic pots with holes to accomodate the roots and use organic potting soil in the pots. I stacked the pots, so the more light demanding plants can be closer to the light source.
Tanks are a little ugly, but you can save a ton on lighting.
