Ep 33. Pond Maintenance, Demilune Table

In episode 33 of season 20 of Ask This Old House, the team takes on two different projects- maintaining a backyard pond and building a demilune table. First, Roger Cook visits a homeowner who needs help taking care of his pond. Roger provides some tips on how to maintain the pond and keep it healthy for fish and plants. He also shows the homeowner how to properly clean out the filter and pump.

Next, Tom Silva is in the workshop building a demilune table, which is a half-moon shaped table that can be used as a console table or entryway table. Tom demonstrates how to create the curved shape of the table using a template. He also explains how to make the mortise and tenon joints that hold the table together and how to attach the legs.

Back outside, Roger returns to the pond to finish up the maintenance work. He shows the homeowner how to skim leaves and debris off the surface of the pond using a skimmer net and how to add beneficial bacteria to keep the water clean and clear. He also demonstrates how to divide and repot aquatic plants to keep them healthy and thriving.

Finally, Tom returns to the workshop to put the finishing touches on the demilune table. He sands and stains the wood, then adds a decorative edge to the table using a router. The completed table is both stylish and functional, and Tom shows how it can be used in a variety of spaces.
