otto--any luck on your application? my pond is full and will wait till middle or end of summer next year when my spring stops runing to see how fast water drops---i still have two tubs of DBS200---is this aquaseal a similar product or do you know? seems cheaper at first glance---also no toxicity to fish? i am thinking of putting a gate valve on back side of sipon pipe and adjusting outflow so as to raise the pond to maximum height/level--i may need to raise my "runaround" a foot and a half or so. just a thought to get max pond level heading into next summers georgia drought.
