Ok guys this is kind of a long question so please bear with me. I recently ordered a wendtii crypt red, dwarf sag, and java moss, along with some Natural Advantage Rootgrow Tabs for my 10 gallon aquarium. Now I placed a few tabs in the gravel near the plants and one underneath the java moss as I attached it to some wood. I also add a cap full Plant Gro Iron Enriched Liquid Fertilizer. Recently, the java fern has been turning brown, and one of the crypt leaves seems to be dissintigrating slowly (crypt rot?) I also noticed that my sag has been producing runners I think. I was just wondering if anybody could give me some advice on these issues. Thanks a lot!
