Today I looked at my flowers and some not all of the leaves were looking sad so I took the deck off to look and while the water looked ok I saw algae on the pods as well. On the sides of them to. I removed all the pods and placed them in a bowl. I cleaned the deck and bowl, changed the water. Also I took each pod and rinsed then under cold water to remove any algae. So now it is all clean and I will wait to see what happens.
