How to Kill Pond Bacteria With Vinegar
- 1). Skim any loose debris floating on top of the water.
- 2). Drain, pump or vacuum all of the water from the pond. Scoop out any residual detritus settled in the bottom of the pond and vacuum out any sludge.
- 3). Create a solution of 70-percent water and 30-percent vinegar. Scrub the pond walls or liner and any rocks with the solution. Another option is to pressure wash the interior of the pond with the vinegar solution.
- 4). Rinse out the inside of the pond and the rocks, continuously draining or vacuuming the water, to get rid of all vinegar residue. Rinsing stone-lined or concrete ponds is especially important because, as an acid, vinegar may etch the surfaces.
- 5). Take apart the pond pump and soak all pump parts, including the filter, in a solution of 50-percent water and 50-percent white vinegar. After several minutes, rinse the parts thoroughly with fresh water.
- 6). Refill the pond with dechlorinated water. Add beneficial bacteria to the water, which is available in liquid form from pond suppliers. Follow the directions on the bottle regarding the amount to add.
- 7). Wipe pond plant foliage with a sponge dampened with the 30-percent vinegar, 70-percent water solution. Rinse all pond plant foliage gently with fresh water before replacing. Let the water come to temperature before reintroducing the fish.
