Fluval CO2 Equipment, available at aquapet.co.uk

Carbon Dioxide is crucial for the growth of plants, particularly those inside your aquarium. Plants convert gas and light into growth in a process known as photosynthesis and can be seen as oxygen bubbles forming on the plant's leaves.

A small increase in CO2 will improve plant growth, however the level of CO2 must remain stable while the plants are under lighting - else algae will grow and cause headaches and frustration for you. If your aquarium set-up has high lighting levels then CO2 is essential, otherwise they wont be able to cope with the rate of photosynthesis required leading to unwell plants.

However, keep in mind that CO2 is toxic to livestock - so never add too much. Overdosing CO2 is the biggest killer of fish and shrimp, therefore a CO2 Indicator Kit and Bubble Counter is recommended to monitor the approximate levels inside your aquarium.

Up-to 30ppm of CO2 is considered safe for most fish and shrimp, but some species vary and are more likely to suffer the effects of toxicity than others. Fish from oxygen-rich environments are typically the most sensitive.

We recommend you check your fish late at night and first thing early morning when setting up a CO2 system inside your aquarium, as plants produce CO2 and use oxygen at night.

In the event of an emergency, perform large water changes to reduce the amounts of CO2 present in the water.

With this in mind, we're proud to have in stock Fluval CO2 Equipment, a broad diverse range including pressurised kits, replacement cartridges, indicator solutions, bubble counter and ceramic diffusers and more!
