Usually, when it comes to keeping a fish tank, most people simply choose to change the water. However, there are still many ways to clean a fish tank without changing the water that are easy to apply. So is there a way to keep fish without changing the water while still keeping it clean? Follow the detailed guide below, compiled by Đức Bình Microbial Products!
How to clean a fish tank without changing the water
1. What Causes a Fish Tank to Get Dirty
Before learning how to clean a fish tank without changing the water, you need to understand what causes sediment to build up and the water to turn cloudy.
1.1 Excess Food Buildup
Many people have a habit of scattering large amounts of food for their fish. The food that is scattered isn’t always fully eaten. This is one of the leading causes of contamination in fish tanks.
Excess food can easily contaminate the tank water
Leftover food that fish don’t consume causes the tank water to turn cloudy and develop an unpleasant odor. If not treated promptly, the fish may become sick.
1.2 Certain Types of Fungi
The environment where fish live often contains certain types of fungi. They float on the water’s surface and accumulate in patches, causing the water to become cloudy.
If not removed promptly, these fungi create favorable conditions for other pathogens to develop. Not only will the tank water become cloudy, but the fish will also be at risk of disease.
1.3 Substandard Water Treatment Systems
When keeping ornamental fish in a tank, you usually need to invest in a water treatment system. If this system doesn’t meet standards or becomes damaged, the tank water will become cloudy more quickly, creating conditions for bacteria to build up and negatively affecting your fish.
The water treatment system must be installed correctly. After installation, you should test the operation of the water treatment equipment.
2. How to Clean a Fish Tank Without Changing the Water
Besides changing the water, there are many other ways to clean a fish tank. These include installing a beneficial bacteria filter, adding tank-cleaning fish, and using biological products, among others. All of these methods are very easy to implement.
There are several ways to clean a fish tank without changing the water. Below are some common methods:
- Use a water filtration system: A water filtration system is the best way to keep your fish tank water clean and clear. The filter removes dirt, leftover food, and fish waste.
- Clean the fish tank regularly: Regular cleaning helps remove dirt that accumulates on rocks, aquatic plants, and other items in the tank. You can use a sponge or a soft brush to scrub dirty surfaces.
- Use fish tank cleaning products: There are several fish tank cleaning products available on the market. These products can help remove stubborn dirt as well as bacteria that cause odor and disease.
2.1 Install a Beneficial Bacteria Filter
If you keep ornamental fish in a pond or tank, install a beneficial bacteria filter. This type of filter is usually made from a special material that stimulates the growth of beneficial microorganisms in the tank while reducing harmful bacteria, helping keep the water in the pond or tank less polluted. A water filtration system is the best way to keep your fish tank water clean and clear. The filter removes dirt, leftover food, and fish waste.
2.2 Keep Tank-Cleaning Fish
Tank-cleaning fish, also known as plecos or algae-eating catfish, mainly live in tropical regions and belong to the Loricariidae family. Their main food source is algae that clings to the bottom of the tank or to aquatic plants. They also eat many other types of food, helping to naturally clean the water.
Keeping tank-cleaning fish – a way to clean a fish tank without changing the water
Tank-cleaning fish are generally not recommended for release into the wild, as they reproduce very quickly and compete directly with other fish species. However, this type of fish is very well suited to ornamental fish tanks. Keeping just a few tank-cleaning fish will reduce cloudiness in the water, meaning you won’t need to change the water as often.
Notably, tank-cleaning fish can survive for months without being fed. This means that when keeping this type of fish, you hardly need to feed them much and don’t need to spend as much effort caring for them as you would with other fish species.
Butterfly plecos, zebra danios, pencil fish, common plecos, and Siamese algae eaters are all popular, easy-to-keep tank-cleaning fish that go well with a variety of ornamental fish species.
2.3 Don’t Overfeed Your Fish
Instead of giving your fish a large amount of food at once, you should only feed them a moderate amount. This way, there won’t be excess food building up and clouding the tank water. This is a simple way to keep the water clear without having to clean the tank constantly.
If you have time, it’s best to feed your fish several times a day. Each time, measure out a specific amount of food rather than feeding them carelessly. As the fish grow, you can gradually increase the amount of food.
2.4 Install Aquarium Lighting
The next way to clean a fish tank without changing the water is to install aquarium lighting. According to research, light is one of the factors that affects the growth of algae and moss in an aquatic tank environment. When algae and moss grow excessively, the tank water tends to become cloudier over time.
You should install aquarium lighting in your fish tank
To limit their growth, you need to control the lighting in the fish tank. Installing aquarium lighting makes it easier to adjust the amount of light. Therefore, in addition to a water filtration system, you should also install aquarium lighting.
2.5 Use Biological Products
Using biological products is the simplest way to clean your fish tank without having to change the water frequently. EMKOI and EMZEO are currently Đức Bình’s two leading products for cleaning fish tank water.
EMKOI – Beneficial Microorganisms for Koi Ponds
EMKOI contains many organic components that help purify water and create an environment for fish to grow quickly and healthily. When using this product, you won’t have to change your fish tank water constantly. Here are detailed instructions for using EMKOI:
Step 1: Shake the EMKOI solution bottle well so that the ingredients in the solution blend evenly.

Step 2: Mix the EMKOI solution with water. Specifically, for every 1,000 to 1,500 liters of water to be treated, mix in about 20ml of EMKOI. When mixing, simply pour the solution directly into the water.
Step 3: Turn on the water paddle wheel and aerator to help the EMKOI microbial solution spread evenly throughout the tank. Clean the tank with this solution once every 7 to 10 days.
Note that during the first 1 to 2 days, the tank water may turn a yellowish-brown color, but it will become clear again afterward.

EMZEO – Microbial Product for Ornamental Fish Tank Water Treatment
This is a microbial product specifically designed for treating ornamental fish tank water. EMZEO for aquariums mainly contains organic microbial enzymes that help remove moss and harmful microorganisms present in the tank.
In addition, EMZEO for aquariums helps prevent pathogens and kill bacteria that cause disease in fish, maintaining a clean aquatic environment. The method for cleaning a fish tank without changing the water using EMZEO is fairly simple.
Step 1: Sprinkle EMZEO powder directly into the tank you want to treat, at a ratio of 3-5g of EMZEO per 100 liters of water.

Step 2: To help the product spread evenly throughout the tank, turn on the pump system.
Step 3: After about 2 to 3 days, use a siphon to remove the sediment that has settled at the bottom of the tank. This can be done regularly, about once every 10 to 15 days.
