Keeping the Fish in Your Outdoor Pond Healthy

Clean the Pond Regularly

Over time, garden ponds naturally accumulate debris, dirt, and litter or plastic that gets caught in the wind. Even natural debris such as leaves can become sludge and disrupt the natural balance of the pond. To prevent this, use a skimmer net regularly and remove sludge at the bottom of the pond with a pond vacuum. After vacuuming, replacing with new, fresh water is good for the fish; it helps them grow and build a strong immune system. Only change 25% of water at a time.

Filter Maintenance

Biological filtration kept active and maintained is a must for colorful, vibrant, fast-growing fish and plants. Filter media, inside the filter, can over time get clogged (even look dirty, although it is not). Clean the filter media (squeeze and rinse) in the old pond water being taken out as you do the 25% water change from vacuuming (never use chlorinated tap water to clean the media as this will disrupt the good bacteria needed in the filter media).

Feeding the Fish—Aquatic Vegans!

Pond Goldfish (Koi, Shubunkins, Sarassa Comets) do not have stomachs, but instead have very long intestines. Foods that normally would get digested in the stomach (as in other fish) are not good; we want to feed a food that will be absorbed as it passes through the intestine. Digestion requires a particularly alkaline diet that is high in vegetable matter. Practice feeding at the same time and place and your fish will come to know and anticipate and be eagerly awaiting you!
