Turns out I am going to hold of on pumping it out, I have tons of tadpoles in there now and want to give them time to grow up. Also somehow wound up with some bluegills in the pond this year, they are about 2 inches, I'm assuming the eggs rode in on the foot of a bird from the neighbors pond.

Can anyone recommend a polymer for me to try. I looked at ess 13 and also the DB110 that is all I can seem to find. From a cost standpoint, DB110 seems to be much cheaper. Any recommendations.
