Question for the experts,do i have enough light in my tank to start growing plants. I have a jewel rekord 120(120 litres) with a boyu t5 x3 21 watt light unit. Also have a co2 reg with the magnetic selanoid. Filter is fluval 206,im aware that i need another external to make the 10x filtration but was wondering what ferts people recomend and just if the lighting was enough.
