I'm going to be purchasing a finnex planted+ 30" light for my 20 gallon long soon and was thinking of moving on up to a bigger tank. I'm torn between a 29 and a 37 gallon tank. Both are 30 inches long and will fit my light and my stand, but I don't know if the light will reach the bottom of the 37. It's 23 inches deep. I plan on carpeting either dwarf tears or dwarf hair grass.
