Hi to all,

Need advice... recently i found brown spots on my Hygrophila difformis, Wisteria. And it seems to be spreading. Anyone has any idea what's the cause and how to cure and prevent it?

Mine is a 6ft tank, but only abt 40cm deep. Using taiwanese brand of base fert w abt 8cm of gravel. No liquid fert used. Using cylinder co2. 2 X FL w reflector used.

Thanks!
