What Is Wrong With My Tank?
I have a 20 gal tall that's fairly heavily planted. I had 2 apistogramma but now I only have the female left and she hardly eats. The tank has been set up for a little over a month. I was regular on my water changes (2x a week) but now I do it about once every week and a half. I've been dosing once a week Flourish excel, potassium, iron, and comprehensive supplement. I don't have any meters to do any readings so I know nothing. My plants are melting but still making roots. The indica in one of the pictures is melting on the bottom half and then rooting where the melting is ending. Some of the micro swords are making runners but that's about it. My lighting is a coralife 10,000K 65 Watt. And I'm not doing any kind of CO2. I know little to nothing about planted tanks. This is my first planted tank ever. Please let me know what you think might be wrong with it and how to fix it!
Pictures are before and after and pictures of the melting.
