I have been reading about siphoning....I could do the bucket brick method easily in my little pond...if you have seen my pictures you will see a white overflow pipe...also there is a white plastic bag down in the pond where i think the leak is...when is it appropriate to siphon...when is the best time of year for pond repair ...since it is so low I am thinking maybe herons can enjoy the BG...i realize my pond is a minature...but it is so great to be able to walk out the back door and go fishing...it used to be so fun...anyway I know I am ignorant on this subject so bear with me...
