Thanks Meadowlark. Not having any useful experience in pond management, I really wasn't sure if the tea color or silt was a problem that needed addressing. I'm happier hearing to leave it alone...the depth is fine. Now I just need to explain to the family that the squishy stuff on the bottom is here to stay so enjoy it! They're used to the beach, so when the silt oozed between their toes, they just about flipped! Thanks.
