So I'm still quite a beginner with having a planted tank and I thought everything was going to be great. I did lots of research but it seems like non of it paid off It's a 10 gallon and I only have one amazon sword. I'm using Fluval Stratum as my substrate but I don't have any supplements. Could that be the reason they are dying? I've tried to have a planted tank three times but I've never been successful. Now I'm nervous to buy more. It just seems like the sword is almost rotting from the stems and turning a clear colour, but the roots look healthy. Should I take it out of the tank or could it somehow grow back? I don't know what I'm doing wrong! Please help.
