They have been closed now for a few days im not sure what is going on but i need to find out how to cure whatever is growing on them that is keeping them closed hope someone can help.
most palys always have stuff on their stems. Sand or any deitrius. The green stuff is algae you can take off with your finger, a qtip or a soft brush. You can also try a peroxide dip for 15 min. 2-4tbsp to 1 litter of water. I usually leave them for 5 minutes after they start to bubble.
