Decided to flood the tank. This turned out to be premature. The HC's in the front portion of the tank began to float. The roots were not as well established as I'd like it to be relative to those in the elevated area of the tank. The current fauna in the tank are pearling nicely. But I am very concerned that there will be more floaters in the near horizon.
I am struggling with finding the patience to have the nice meadow I intended to achieve with a dense carpet of HC's. From what I understand, it will take a long time for the carpet to heal the front of the tank submerged. So I ordered two pots of HC's to plant in the front as I was hoping to plant them with the rock wool. The idea is that this would anchor the HC's down.
