How to clean a pond without draining it

The sudden increase in temperature is always a difficult time to handle. The microalgae in the pond’s water (not often visible) benefit from the abundance of organic matter to grow and invade every aspect of the environment. They are more prolific than aquatic plants, which design to reduce how much light. The water of the pond suddenly changes green. Here are some suggestions on how to clean a pond without draining it.

Step 1

The first thing to wash in a pond is floating debris on the surface. It’s likely to sink and cause sludge to deposite on the pond’s floor. Removing the most floating trash can recommend before cleaning the pond’s liner. You’ll have to clean the pond again in the future when it begins to sink. Floating debris can include leaves, sticks, twigs, and dead or dying insects. You can clean them manually with a simple fish net. You can also employ an automated Skimmer System to ensure that you are constantly cleaning up.

If you’re considering a pond net, choose one with a wide opening for the backends and a fine-grained mesh to ensure you quickly n capture all kinds of dearly. Pond skimmers are an excellent long-term solution to keep debris from falling into your pond or if you’re surrounded by fish and want the best clarity in your water. Box skimmers work to get rid of the surface dirt quickly and can provide a vast capacity for larger ponds, while smaller ponds could benefit from submerged or floating skimmers due to their less high price of purchase.

In contrast to nets, skimmers are better investments over the long term because they can remove smaller particles that aren’t always easily visible. They can also work 24 hours daily to ensure the surface is dirt-free. However, suppose you’re looking to build a smaller pond and don’t worry about keeping track of your daily maintenance. In that case, the pond’s net will be plenty!

Step 2

The next thing to do is eliminate any bottom sludge you might have. But even though it’s not necessary to eliminate the entire amount. It may be beneficial to get rid of most of it before winter to protect your fish during hibernation. This is typically the point at which you might feel it’s beneficial to drain the pond. However, it’s only necessary when you’re manually taking out the sludge using the help of a rake or net. Another method of removing the bottom muck that is more efficient and less time-consuming is buying an efficient water vacuum. Pond vacuums can enable you to scrub all the dirt from your pond’s liner without draining the water.

The most effective models will come with a selection of head attachments. It is suitable for cleaning areas that are difficult to reach in the pond. If you own a deep pond, you’ll want to choose one that can maintain suction at sound levels and has an extendable handle that makes cleaning easier. The basic models reduce suction the deeper you go. And while they are suitable for smaller ponds, they might not be able to handle cleaning the most profound parts in larger ones. In addition, it is essential to use an efficient vacuum with a solid discharge system to keep it clean and simplify to eliminate garbage. We recommend two vacuums, the Oase PondoVac 4 and the Matala Power Cyclone, as they come with all of the above features and are suitable for small and massive ponds.

Step 3

After removing most of the sludge in the bottom, it is possible to supplement the pond with an organic beneficial bacteria product to eliminate any leftover debris of sludge removal treatments that employs high-quality bacteria capable of breaking down organic matter within the pond. Like a pond’s natural healthy bacteria, the sludge removal bacteria work precisely the same way and can boost the wild population after extensive cleaning. Suppose you own a pond for wildlife, and you want to keep the majority of your sludge. In that case, you could instead add beneficial bacteria to enhance your nitrogen cycle.

Sludge can benefit wildlife ponds because it provides the plants with nutrients and can also provide micro-organisms and insects with food. Sludge problems that are excessively accumulated occur primarily with fish, as a byproduct of decomposition itself is ammonia which is harmful to goldfish and koi. If there is no aquaculture in the water, adding good bacteria could be a less expensive and more effective method of controlling the sludge than removing the entire thing using a vacuum.

Step 4

Although algae isn’t technically a waste, manage it and remove it to ensure it doesn’t cause problems with the water’s quality or accumulation of sludge. A small number of algae in ponds can be advantageous, offering hiding spots for predators and providing good fish food. Algae problems arise when it grows uncontrollably and quickly becomes a significant problem for the pond’s system. Algae blooms can cause issues with sludge when old plant species die and then sink into the bottom of the pond, decreasing the oxygen content because bacteria are working to remove the waste.

It is not necessary to drain your pond to fight algae, and even string algae attached to the pond’s floor can eliminate using the correct mixture of treatments. To fight free-swimming algae, it recommends installing a UV clarifier. It filters water and kills algae on a cell level. The pond vacuum can quickly work the nuisance plants to remove algae with a deeper string that the clarifier can’t filter. Control the algae by adding other plants to the pond because they compete directly against algae to get nutrients and slow down algae growth. To prevent algae fast, it recommends using an ultraviolet clarifier, and an air vacuum will be enough to eliminate most of the algae without draining the water.

Step 5

The last thing to consider while cleaning a pond is to ensure that the water filtering is as efficient as it is to help reduce the need for maintenance and cleaning. A pond that has a well-functioning biological filtration system will have no issues in terms of water quality, and any filter with a high-efficiency mechanical media will help reduce the overall debris that accumulates in the pond. However, filters shouldn’t be cleaned since they could damage the bacteria living inside this box required if the media has become blocked entirely. Additionally, mechanical media may damage over time and require replacement. Every couple of years, ensure the proper filtration process is in place. A well-functioning filtration system will lower overall cleaning costs and improve the water quality for fish in ponds.

How to clean the pond bottom

Vacuum up the mud

An easy procedure is to get rid of the silt from the bottom of the pond by using a vacuum cleaner. Small animals are essential to the overall ecological balance of the water the body can take out. Take care when taking the mud at the bottom of a body of water so that you don’t accidentally harm creatures living near the surface. If you vacuum, make sure to take off all the silt. Always leave only a few inches of mud on the bottom.

Biodegraded sludge

The silt layer can be biodegraded over time by regularly adding specific bacterial culture preparations. Bacteria aid in the biological degradation process that organic materials expose to once they end their lives. Find advice on purchasing and using cultures at the OBI store.

It is important to note that any alteration in the nutrient structure or balance of substances impacts the entire pond ecosystem, particularly impacting the food chains. The introduction of specific preparations will, therefore, only be a last resort. In the longer term, avoiding over-accumulating organic matter on the water bed, e.g. B. is crucial to using a leaf-safety net.

Make sure the lake is clean

If the water balance is already affected permanently due to the presence of mud and requires a thorough cleaning of the pond. The period of hibernation is likely to be inevitable. To do this, you must take the water out and transfer the animals to containers without having enough remaining water from the pond. The mud will then remove using a shovel, and the banks can scrub with the help of a bristle. Then, fresh water with a bit of lime is added to the animals, and plants can use it again.

Eliminate sludge

The best method to stop silt from developing in the initial stage is to adopt preventive measures. Leaf safety nets are effective in autumn since it keeps falling leaf litter from blowing into the pond. Cutting back lush plants or plant residues and removing the clippings helps ensure that less dead organic matter is pumped into the pond. Reducing the number of fish in the pond and using solar or electric pumps to ensure adequate water circulation is also beneficial.

When is the best time to clean a pond without draining it

While cleaning is a task that can be carried out as often as you require. The most effective times to clean ponds are at the beginning of spring and the end of autumn. Cleaning towards the end of autumn ensures a minimum of waste going into winter. Allowing fish to enjoy the most comfortable (and secure) hibernation/torpor. The accumulation of sludge and other debris in ponds can create many issues for fish. Particularly if the water freezes and there is no gas exchange. In such instances, toxic substances will gradually increase, and the oxygen content will decrease. Eventually making fish sick or dying by spring. Conducting a thorough clean towards the end of autumn is a common practice among fish keepers and is an option in the event you have koi or goldfish.

A small cleaning can be done in spring when temperatures increase, and the fish are more active. Although it’s not as thorough as the one, you did in autumn, adding beneficial bacteria and eliminating any remaining debris is an excellent idea to provide the most efficient start to the new year. Other instances when you might have to cleanse your pond could be to eliminate the overgrowth of algae and fallen leaves or overgrown plants, such as duckweed.
