Hey guys, my wife is giving me her new unopened 20 gallon marineland led kit. I plan on doing live plants. I highly doubt this stock light will be sufficient. Plants will be low to medium light, Excel for co2. I have Java Moss, Java fern, Amazon sword. Cabomba, and water wisteria in my 55. Will I have to replace the entire hood, or are there lights that will fit in this hood that will grow these plants?
