I am trying to choose plants for my 10 gallon freshwater aquarium. The water I am going to be using for the tank has tested 0ppm for nitrate, nitrite, and chlorine. It tested somewhere between 150-300ppm for hardness and 300 ppm for alkalinity. The pH is somewhere between 7.8-8.4. If possible, I am looking for 2-3 plants that either need to be planted directly into the plant substrate or attached to rock/wood, as well as, a floating plant. Ideally, these plants wont grow to be too big as I am only able to provide a 10 gallon tank, as mentioned above. Also, I have decided that I will be purchasing guppies to put in the tank (I am not sure if this will influence the type of plants I should use, but I thought I should add it just in case). I've read that a full spectrum LED light works best for most plants, so that is what I am planning on getting right now. If there is anything I need to get for the plants in addition to what I might already have, please let me know.
