Im looking for a small foreground plant for my tank and was wondering if I had enough light to grow a carpet of Glossostigma elatinoides. Tank is 48" x 15" x 18" around about 200 litres with 90 watts of light with reflectors 2x arcadia freshwater and 1 origional. I have D&D co2 kit giving me about 25ppm and have just started dosing with pre mixed dry ferts that I bought of ebay. As for substrate its just plain gravel.
