I'm totally new to plants but since I'm starting up a new tank I decided to try and keep some. I'm setting up a biotope so just planned to try one species. A month ago or so I got a bunch of Amazon frogbit off of ebay for pretty cheap. They looked pretty beat to me (the plant newbie) when they came because a lot of leaves were off and all of the roots. I put them in and the next morning saw little roots. From that point on I started getting excited about plants. Something I never thought would happen. I couldn't wait to see how much they grew everyday when I turned the lights on. I was getting new leaves, baby plants, and roots that nearly touched the bottom of my 40 gallon breeder. I thought things were going smooth and it looked really good. Then after about three weeks of that I noticed leaves turning dark brown/black. patches at first that I removed but eventually it was all of my plants dying. I'd like to try again but does anyone know what I did wrong? I'd prefer not to have this happen again. I'm not sure what info you guys need. I didn't fertlize (have since bought Seachem Flourish), I have 2 39W T5 HO 6700 K bulbs sitting right above the tank, no CO2 but an open tank. Any advice for me? I'm open to anything.
I did try to google this but came up with too much nitrates. When I tested that I was only at 20 ppm. So confused.
