I have a 10(+) year old koi pond with waterfalls. It was installed with an Aquascapes pond kit. Over the past month, I noticed the ground around my skimmer box was wet. With the recent rain from Hurricane Sandy, the pond flooded and I went to clean leaves out of my skimmer box net and observed ‘wisps’ of muddy water weeping in around the skimmer box outlet tube. Is this something that can be individually fixed or am I looking at a whole new skimmer box? Note: when the water level in the skimmer is below the outlet tube, I do not have the wet ground issue. Thank you in advance for your help.

Your equipment meaning your biofalls and skimmer were sealed originally with black silicone sealant but after a period of time, the seal may break and and needs to be resealed. This involves removing the plate and screws and cleaning the liner and then resealing, adding new screws to the unit and reattaching the liner to the unit. Call your certified contractor to do this properly.
