I have a 29g freshwater community tank that has been established for over a year. The substrate is small gravel. I have several live plants: jungle val., swords, water wisteria, red lud., java ferns, and some other misc. I add fert.(contains iron) to the water after each water change.
My jungle vals. and swords are slowly dying (turning brown at the root crown). Is there anything that I can add to the substrate that would help? I do not want to add CO2.
