At Hydrosphere Water Gardens & Fisheries pond fish are our speciality. We quarantine all our new arrivals of koi and goldfish and inspect them before they are allowed to be sold. We only import koi from respected breeders that are regularly tested for KHV and SVC. We guarantee all our pond fish to be healthy and free from disease, so it’s safe to add them to your fish collection. Due to factors beyond our control once the fish leave our location (such as water quality, fish stress etc) we guarantee our fish for a period of 5 days from the date of purchase. We also recommend that all new fish (from us, or any other supplier) be quarantined before introducing them into you pond.
We have an excellent selection of koi all season long to suit every taste and budget. We import quality Japanese koi directly from the best breeders in Japan. All our Japanese koi are quarantined upon arrival, and are sure to be healthy when you are ready to add them to your pond.
If you are new to keeping koi and aren’t ready to pay the higher price of Japanese koi, or just have a smaller budget to stick to, we also have some great domestic koi available imported from one of the premier koi farms in the United States.
Goldfish make great pond fish for ponds of any size. However, if you have a small pond, goldfish are the best choice because they don’t grow nearly as big as koi. We always stock red and white Sarasa comets and Shubunkin goldfish in a range of sizes sizes. We also occasionally have Wakin goldfish available.
You can use rainwater to fill your pond, but keep in mind that it is very soft water. If you primarily use rainwater, be sure to check your pH regularly because it could become too low and cause serous problems.

If you plan to keep koi in your pond, it should be at least 4’ deep to give them enough space to swim and develop properly.
The beautiful koi we see today originally started out as bland coloured carp that were raised for food in Japan. It wasn’t until the early 1800's when farmers began to notice interestingly coloured fish appearing in their rice paddies and began selectively bred for colour.
Although algae can be a pond owners worst problem, it has many potential benefits outside of the pond such as, a source for biofuels, fertilizers and nutritional supplements
Nualgi is a product that natural fights algae in your pond. Nualgi provides essential nutrients promote a diatom bloom. These invisible diatoms outcompete the algae in your pond for the nutrients they feed on. The algae soon starves causing the water to clear.
Most water lilies need at least 6 hours of direct sunlight a day to bloom, however there are some Shade Tolerant Water Lilies that will perform well in more shade and bloom quite well.
Costia is common microscopic parasite that is active in cool water. They are smaller than most parasites and are shaped like a comma when viewed under a microscope.
Performing regular, parial water changes is a great way to maintain optimal water quality. Changing 10%-15% of the pond water every week or 2, helps to flush out nitrates, tannins and other waste products while replenishing essential minerals.
Koi make wonderful pets for larger ponds. Because they can often grow up to 24” / 60 cm long (or even larger), they are not well suited to small ponds. Ideally, your pond should be a minimum of 48” / 122 cm deep to adequately house koi.
Pond Flocculants help to clear cloudy water by clumping small particles together so they can be trapped by your filter.
Frog and toad tadpoles are wonderful additions to ponds. Not only is it fun to watch them develop from tadpole to frog or toad, but they also consume copious amounts of algae
