melting sword plants
Ive got an issue with some assorted sword plants that Ive had in a 50 gallon low tech tank ( cycled Aquasoil, no CO2, no ferts yet-other than root tabs and the ferts from the Aquasoil, moderate fish load, 84W T5NO lighting < two Coralife T5NO strip lights with 2x21W T5NO bulbs > )
The swords are melting like you would see with a Crypt that was just disturbed. The leaves are literally turning to mush. I do have an Ancistrus pleco in the tank and he hangs out on the leaves of some of the swords, but I dont think he is capable of doing this type of damage.
Tonight is water change night for the rest of my tanks, so Im gonna do a 50% water change and dose the tank with NPK and traces as well as Empsom salts and see how it does. I really dont think I have enough light on this tank to cause the need for ferts. The swords have been in the tank for a couple of months-the soil has been wet since January.
Any thoughts on what might be the culprit for the melting?
