Neutro CO₂ - Liquid Carbon for planted aquariums

Neutro CO₂ is a liquid source of carbon for the planted aquarium.

For those of you not familiar with it, carbon is essential for all healthy plant growth and can be provided via gas, or liquid. The liquid form is less potent than gas but still very effective. It won't make your plants pearl (this is when you see O2 bubbles coming from the plant) but it will help them grow. Plants that have access to liquid carbon will do far better than those without.

What happens when plants don't have access to carbon?

Tap water has zero carbon in it so if you're not adding any to the water you can safely assume you have no carbon at all. So if you're not dosing it, plants will not photosynthesize as they should. As a result, they stop growing (or show stunted growth) and can't compete with algae for nutrients and the downward spiral begins. If this carbon deficiency continues, plants inadvertently (out of their control) release sugars and other nutrients which attract algae and it's these sugars and nutrients they so desperately need, but just can't hang onto.

It's a bit like vomiting (sounds gross but true). Without carbon, plants lose energy, nutrients, health and well-being. Their colours disappear. The end result? Algae everywhere.

So you can see why it's actually very important to dose carbon and why we recommend that all plants receive a daily dose because, without it, they will always struggle.

So the sooner you dose liquid carbon the better.

Can I double dose if I have algae?

You can - for short periods but no more than double. It's important to understand that if you do have algae, your tank has an imbalance and this isn't just down to carbon, it's other nutrients versus the amount of light you are pumping in.

Can I spot treat?

It is possible to spot treat plants or wood that have algae growing on them. Simply by using a pipette and extracting some Neutro CO₂, squirt the carbon onto the plant or wood when it is outside of the water. Wait for 10 seconds then put it back into the water. You can also do this when performing a water change (it's easiest that way). But if you leave liquid carbon on for too long you will kill the plant.

DOSAGE: Add 1ml per 50L every day. It doesn't matter what time of day you dose this product, but it does need to be added every 24 hours.

Bottle sizes: Small = 500ml,  Medium = 1000ml,  Large = 2000ml, XLarge = 4000ml.

This bottle has a cap which measures 10ml. In order to dose you can pour directly into that or use one of our dispensing bottles (which is on the better together promotion on the right hand side of the screen).
