These guys did a fantastic job for me. Matt and Noah (the owner's brother and son, respectively, I believe) were incredibly careful and thorough. They got the fish out, patiently mucked out the muck, pressure-washed the stones and sides. They replaced the filtration medium and patiently re-positioned the plants, air-stones, and lights according to my nitpicking instructions. They were beyond patient with me: at one point, I asked if the muck from the pond smelled bad. They said "no", so I said, "good, how about scattering it around the roots of my roses?". And they did. They also erected the pyramid-net that sits over the pond to keep out leaves and herons in the fall in winter. The next day, the pond was crystal clear and the fish were swimming around energetically -- even trying to spawn, I think! I could not be more pleased with the job Matt and Noah did. The cost was a bit pricey, including the $120 for travel time. Because of that, I will probably do the spring start-up myself. But I think Knee Deep will be my go-to guys for fall pond maintenance from now on.
