Neutro Combo - High Tech is an ALL IN ONE kit for the High Tech (injected with pressurised CO2) aquarium. You make a little saving too!!

Neutro+ is a liquid plant fertiliser which provides trace elements and macro nutrients (NPK) for high tech planted aquariums. The definition of 'high tech' is injecting with pressurised CO2 with moderate to high lighting. This all in one solution makes dosing really easy. The results are impressive and plant growth is better, healthier, quicker and stronger - but only if you dose as recommended.

Dosage: This product needs to be dosed daily so that your plants have a steady stream of nutrients. There's little point in dumping a weeks worth of fertilisers in one go. Simply add 5ml per 100L every day. It doesn't matter what time of the day you dose, as long as it's every 24 hours. Over time as your plants grow, you need to increase the amount of Neutro+ you are adding. Larger plants need more food than they did, let's say a week ago. If you don't give them the food they need, the plant will struggle and algae will begin to take hold.

It's worth noting that regardless of what type of planted aquarium you have (i.e. low tech or high tech), we recommend using Neutro CO2 which is a liquid carbon supplement (see related products for more information). This will help all plants not only by adding another source of carbon, but also keeping any algae at bay.

Bottle sizes: Large = 2000ml

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 not as potent as the gas but is 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.

In addition to this, if you over dose Neutro CO2, it can have a negative effect on algae (helps reduce it). However you need to take care when overdosing, and increase it slowly. Perhaps 25% extra, then monitor the results. We do not recommend more than double dose.

It is also 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.

DIRECTIONS: Add 5ml per 250L every day. It doesn't matter what time of day you dose this product, but it does need to be added every 24 hours.

Ask a question about this product
Hi what size are these bottles


Large bottles are 2 litre.

So this combo you use with pressurised co2 which is what I have but I have hair algae and my plants are not looking too healthy even though co2 is set correctly could it be my fluval led plant 3 and fluval aqua sky 2 that are not giving out enough light ?


hair algae is caused by excess light relative to the amoiunt of fertilisers you are adding

either rdecrease your lighting intensity and duration (easiest) or add more fertilisers

So this combination is what I would need and not just the neutro ?


If you have pressurised CO2 then yes
