In this PondXpert guide, we will explore the why and how of pond aeration, focusing on the benefits of aeration, when your pond may need it, and the different types of pond air pumps available in the UK.

Performing regular water changes helps dilute the nutrients in the pond water, reducing the food supply for algae. Aim to change 10-20% of the water weekly, and use a dechlorinator if you’re using tap water.

For the best results and algae prevention, adding more barley straw a few times a year is good practice to make sure there is always a low concentration of hydrogen peroxide in the pond water.

When looking to purchase barley for ponds, you’ll likely come across two different products – barley straw and barley straw extract. Barley straw extract is a liquid formula which is more concentrated and faster to act compared to physical straw. Both of these work in a very similar way.

Remember, barley straw is a preventive method of algae control, not an algae killer, so a good result from barley treatment would be less algae returning the following year. To remove large algae blooms, always use a direct treatment method and only use barley to supplement the process.

The nitrogen cycle is a natural process which is responsible for the conversion and generation of different nitrogen compounds. Ammonia is a nitrogen compound, excreted by all fishes, and is extremely toxic to them.

Remember to perform partial water changes, vacuum the substrate and clean decorations to maintain a healthy aquatic environment!

An Ultra Violet Clarifier will not really work on blanketweed as it will not pass through the pump and filter. A UVC unit is there to make the single-cell algae clump together so it can be taken out by the filter.

Moss balls, Aegagrophila linnaei, were first introduced into the aquatic hobby in the 1970's. More recently, the shrimp keeping hobby has expanded their popularity.

Only a regular addition of CO2 creates the natural basis for healthy, strong plant growth, lush green leaves and bright colors. The plants produce more oxygen for the fish, ensure better water quality and actively prevent algae.
