Mid July I had the disaster that wiped out my tank(pump quit in sump and tank hit 115F without the water going to the chiller). A little more than a month later the pod population has exploded. My Sump/refugium was never affected by the heat although the ammonia spike hurt the life in it. The pods have reseeded in the main tank and are incredible. Here is a picture of some on the glass. The pic is about 1.5 inches accross.
The pods on the glass are nothing compared to the amount on the rock and sand. They are litterally on top of each other 2 or three deep in some places(couldn't get a good pic in those spots, bad angle). I have never seen them this thick. I guess thats what happens with a tank full of food(dead things) and no pod predators.
