ok, so went back to the store and bought more java fern. Did my usual ritual of 90 sec bleach dip(10%bleach,90%water) ,then good rinse ,then in tall vase with treated (Prime) water for 2 weeks q-time. This is my usual plant ritual and never had problem , but now I notice small holes in the ferns, pin-size. Wonder what it is from ? Never saw this before . Could it be a lack of fertilizer prob ? I have never used them . I do take some water out of the tank with nitrates and add to the q-vase every so often. Not sure I should put it in the tank next week.
Any advice/ideas would be helpful. I also have a small anubus plant in there wtih it ,but looks fine.
thanks , Georgie
