If you are a gardener, the pond will be your favorite part of the garden to tend. It typically takes less time and effort than a perennial or vegetable plot and the results will make you want to linger at the water’s edge! (pun intended)

Listed below are the ‘tools of the trade’ and a set of typical tasks with our recommended frequencies. Although each pond is different, and each pondkeeper has a different bent on the detailing, following these guidelines will NOT lead you astray! A little bit of effort on a regular basis will reward you with a beautiful, healthy pond that you will enjoy for many years!

Handy Equipment and Gear:
Bucket- for storing water treatments, fertilizer tabs, etc.
Floating Tray- for tools and debris while in the pond
Dowel or Poker (1/2” diam.)- to push in and cover fertilizer tabs
Stainless (non-rusting) Nippers with BRIGHT handles- for nip-trimming
Course Net (1/4” Mesh)- for dredging big stuff or catching fish
Fine Mesh Net (1/16” Mesh)- for dredging/skimming fine stuff
Good Hose End Shut-Off- for numerous uses!
Chest Waders- for body protection, & to keep warm during cool seasons
Long Sleeve Gloves or Gauntlets- for cool seasons
Wet/Dry Shop Vac- to clean out biofilters, skimmers & pond bottoms

Remember to turn off your pump whenever you service your pond - you do not want to expose it to debris while you are cleaning screens and filters! This will extend the life the pump. Leave it off while you dose beneficial bacteria and trim plants...and don’t forget to turn pumps on when you have finished!

Below is a short list of supplies and consumables to keep on hand:

Dechlorinator- Keep enough on hand to treat your full pond

Beneficial Bacteria- Dose regularly to reduce sludge build-up
Test Kits- Buy new each spring for best readings
Aquatic Fertilizer- Your plants will love you
Fish Food- Your fish will love you
Barley Extract or Pellets- They help minimize algae

We have found that routine maintenance of water gardens can eliminate (or at least minimize) the need for full pond cleanings. Draining and cleaning out a neglected pond is a mucky and stressful task for you, your plants and your fish takes a while for all to recoup and balance out again.

If you must do a full pond clean-out, try to plan it for late fall / early winter after the leaves have fallen and while your fish are still strong and healthy.
