How To Get Crystal Clear Pond Water

The plants and the fish in your pond have one thing in common and that is that they need clean pond water to grow and survive. For clean pond water it is important to have a biological equilibrium in your pond. You can get a biological equilibrium by making sure all parameters are right, think about the pH value (acidity or alkalinity), hardness of the water, oxygen content in your pond, solids (waste) and more in your water. There are various purification technologies that you can use to get that crystal clear pond.

Which purification techniques can you use to get clear pond water

There are various purification techniques that you can use for getting that nice clean pond water. Before you decide on what technique to use it is important to understand your ponds details. Gather first information about the following to make sure that you are prepared.

• How much water (liter / gallon / m3) does your pond contain?
• What source of water do you use for your pond?
• What is the temperature of your pond water?
• What kind of fish and plants do you have in your pond?
• What is the pH of your pond water?
• What kind of equipment do you already have installed?

When you have the details about your pond water, then you can go to the next step and that is deciding on the technologies that you can use for your pond. That said, which purification technologies are there that you could potentially use:

• Aeration
• Activated carbon
• UV
• Sand filtration
• Ozone oxidation
• Other technologies
• Pond treatment chemicals

Advantages and disadvantages of pond water purification techniques

All the technologies that you can use have advantages and disadvantages. It is good to be aware of these before you make the selection of the techniques that you will use. Let us go though some of the technologies;

Pond water: Advantages and Disadvantages of Aeration

Aeration helps in removing CO2 from the water and removes certain volatile organics (VOC). The advantages of aeration are the once you have the equipment installed, then it works like a natural process and you do not need to purchase any air. It is very effective for removal and adds as a bonus oxygen to the ponds water and makes sure the water keeps moving. You will have some energy costs and you might get clogged pipes over time. Low temperature can make this process less effective.

Pond water: Advantages and Disadvantages of Activated Carbon

Activated carbon filtration is useful for removing of organic components and also works as a mechanical filter. Benefits of using activated carbon are that it can remove large number of organics and the price is quite low. The disadvantage is that activated carbon becomes saturated over time and that you also need a pumping system.

Pond water: Advantages and Disadvantages of UV

UV is a technology that is effective in reducing microorganisms, bacteria, fungi, and algae from your pond. The advantages are that you do not need to add any chemicals and that is an environmentally friendly process with a relative low energy consumption. The disadvantages are that you need the right amount of energy to make UV effective, it does not remove components and some microorganism might be able to survive UV. UV often also needs additional treatment steps like activated carbon.

Pond water: Advantages and Disadvantages of Sand Filters

Sand filters are effective in removing all kind of particles like seeds, insects, suspended solids and even iron particles. The benefits of sand filters are that they are extremely effective in removing all kind of particles, hardly require maintenance and can work for many years. The disadvantages are that it does not work well with dissolved components and they might get blocked over time due to too much particles being trapped in the sand.

Pond water: Advantages and Disadvantages of Ozone Oxidation

Ozone is extremely effective in destroying organisms, pathogens, bacteria, and some organic components. The advantages of ozone are that it is a common technique that is widely applied, it is produced on location and after oxidation other techniques can remove the components better. The disadvantages are that you do not really remove components so other technologies are needed for that. Ozone can react with certain other chemicals and can be dangerous in usage.

Pond water: Advantages and Disadvantages of Chemicals

There are various types of chemicals like algaecides (you can guess, against algae in your pond), herbicides (against plants and weeds in your pond) and all kind of other pond treatment chemicals. The advantages of chemicals are that they can work very effectively against various components in your pond, however the disadvantages are that you add stuff to your water which can also harm plants and fish if not applied in the right dosing.

Which technology do you select for getting clear pond water

Now that you have run though the steps of having the details about your pond, that you know the technologies that can be used and what their advantages and disadvantages are, you can go to the next step and that is making the treatment plant for your own pond. Depending on the size of the pond it is important to get advice from a local shop or a large company, all depending on the size of your pond, but also what kind of plants or fish you have in your pond. We trust that our information supports you in your journey to get that crystal clear pond water to make your plant, fish and yourself happy!
