How deep do ponds need to be?
How deep should a garden pond be? A depth of 46cms (18 inches) is the minimum depth recommend to achieve a healthy pond balance. At least 40% of the pond area should be at the maximum depth, with the sloping edges stepped for marginal pond plants. The pond should be at least half full and filling. Stock 500 bream per acre. This can be all bluegill or, if desired, 350 bluegill and 150 redear sunfish. If you want channel catfish in your pond, stock at 50 catfish per acre.Typically, ponds with a depth of 3 feet or more are safe, as deeper water will not freeze solid. Even when the surface is fully frozen, fish can survive by staying in the warmer water below. Tip: For koi ponds, aim for a depth of at least 3 to 4 feet to provide a stable winter environment for your fish.I generally suggest 40 gallons per goldfish and 250-400 gallons per koi. With adequate filtration of course. You should aim for 3 inches of fish per square foot of surface area.We recommend allowing 1-2 koi or 2-3 goldfish per 200 gallons of water, so if your pond is 1000 gallons, that’s approximately 5-10 koi or 10-15 goldfish. If you’re starting with young or adolescent fish, don’t max out your fish volume right from the start.
How do you maintain a raised pond?
Raised garden ponds need regular maintenance to support healthy ecosystems with pristine water. Skim your pond often to remove leaves and twigs, which will decompose and cause algae blooms and muck. Equip yourself with a Collapsible Skimmer and Fish Net for routine cleaning to stay ahead of the mess. Water changes should be carried out at least twice a year, normally at the beginning and towards the end of the season, but they shouldn’t need to be done more than once a month. There is some debate as to the best way to source water when filling a pond or topping up after water changing.Size of the pond Larger ponds may require less frequent water changes because they have a greater volume of water to dilute contaminants. For small urban or garden ponds, you might need to change 10-20% of the water every couple of weeks.Install a pond filter: A pond filter is essential for maintaining water quality and clarity. It removes debris, excess nutrients, and other contaminants from the water, which can cause algae growth. Many types of pond filters are available, including biological filters, mechanical filters, and UV clarifiers.Sun or shade? Shade over part of the pond helps to reduce problems with algae and is tolerated by many pond plants and animals. However, ponds with too much shade are not good for wildlife, so choose a spot where at least part of the pond will be in full sun.Before filling with water, it’s a good idea to put a 5-10cm deep substrate such as sand or washed gravel into the bottom of your pond. Next, fill the pond with water. Rainwater is by far the best, but if this isn’t practical, you can make do with tap water.
How many fish should I put in a 1 acre pond?
The pond should be at least half full and filling. Stock 500 bream per acre. This can be all bluegill or, if desired, 350 bluegill and 150 redear sunfish. If you want channel catfish in your pond, stock at 50 catfish per acre. Before adding fish, consider your pond’s size, depth, and water conditions, and consult a reputable fish hatchery for stocking recommendations. For ponds of at least one acre, three species are especially well-suited: largemouth bass, bluegill, and channel catfish.Always take time to build your pond fish stocks up However, World of Water would recommend waiting for approximately 4 weeks after the pond has been planted. This allows plants to get established and gives the fish shelter and natural nourishment.Goldfish. Easiest of the pond fish to keep, being a member of the carp family they can vary in colour from a red to very light gold. They will breed easily producing black young that may turn gold later in the right conditions.In a pond, goldfish can live from 10 to 20 years and occasionally longer. Native fish are not easily available but could be considered by those that are keen to allow frogs to breed in the pond since ornamental fish tend to eat their eggs.
What is the cheapest way to build a raised pond on a budget?
Railway sleepers, bricks, and timber are all sturdy choices for building a raised pond. You could even repurpose a wooden planter, or build a simple frame using stacked pallets. As long as the structure can support the weight from the water pressure and isn’t sharp enough to damage your liner, it’s fine to use. Building a submerged pond is very cheap and simple. Simply dig a shallow hole and using any removed soil to form a lip around the edge. Consider using stones, bark and gravel for a natural finish.

Can fish survive in a pond without a pump?
While fish may be fine for a few days to weeks in a well-planted pond with no pumps or filters, they’ll quickly foul the water beyond the system’s ability to recover naturally. TOP TIP: Overfeeding fish or using the incorrect food can cause serious water quality and fish health issues.
