This is a picture I took of one of my air bubblers the other day before I sanitized everything with bleach including the plant roots. It is about 36 hours after a full water exchange in the tub. Water temperates were about 66-68 and I was stabilizing PH with Citric Acid. You can see in the water that there are quite a few other blooms in there as well. I wish I had taken more pictures of this mess but I was more concerned with not losing everything. The original thread is HERE.
