I have a 20 gallon long. I don't have much experience with plants and I started out with silk plants. Now since I've gotten my Amazon sword and java fern I noticed how much better live plants look in my tank. Right now I'm using an old lamp that can grow plants, but my tank isn't all lit up. I have a glass lid and I wanted to get something that I can use along with my glass lid. What brand/type light should I get? Thanks in advance!
