Aquarium - Liquid CO2 Boost

Aquarium - Liquid CO2 Boost Contents
PFK award

When to use?
All plants need carbon to grow. Aquatic plants obtain their carbon through CO2 dissolved in water. With Liquid CO2 Boost, plants will grow more vigorously, removing algae-causing macronutrients such as nitrate and phosphate.

Use daily, or every other day, to provide plants with a regular and consistent supply of carbon.

How to use?

  • Calculate the volume of your aquarium in litres (length x width x depth (in cm)/1000). 
  • Dose: After water changes and first dose add 2 pumps per 25 litres. Then follow daily dosage of 1 pump per 25 litres.
  • Turn dispenser to unlock, then press down on the pump to dispense.

For best results: Use in conjunction with Plant Boost to provide the trace elements and micronutrients required for healthy plant growth.

“Comprehensive and easy to use, I often like to have a couple of bottles of Anti-Internal Bacteria treatment or Disease Solve to hand. Nice to know that I’m not the only one who rates these products!” Nathan Hill, the Associate Editor of Practical Fishkeeping Magazine

Q: Will carbon remove Aquarium Liquid CO2 Boost or Plant Boost? A: Activated carbon is very effective at removing carbon-containing compounds from the water. Unfortunately, both our CO2 Boost and Plant Boost have such compounds and are likely removed by activated carbon, reducing their plant growth boosting properties. The best way to use activated carbon in a planted aquarium is on an "as and when" basis to remove water discolouration or odours.

  • Terry Jones from Wholesale Tropicals

    We recommend most of the NT Labs products in here because we use them ourselves, chemicals and treatments are very good, as well as all of the food products.

  • Colin Agness from Woodford Aquatics

    We recommend the plant fertilisers because they work so well with the plants, the sinking algae wafers and the sinking predator tablets because they’re brilliant for bottom feeders, and the granular food because it’s probiotic, so it’s really good for the fish’s digestion.

  • Luke Samuel Antony

    I've been using CO2 Boost for about 3 months now and Ive noticed a massive difference in my plant growth. I have also got a plant which has started to carpet which never did before! I've even been able to keep java fern which I struggled to before alive and even growing baby javas. Thank you NT Labs! I've now gone and purchased your Plant Boost to work along side it.

  • FishCove Aquatics from Wimborne, Dorset

    We have been using both the CO2 and plant boost pump bottles now for a year and have seen our plants flourish and grow using your liquids in our 30 litre nano. Simple to use and a product that works. It's easy to understand as we only use two pumps of each daily, this makes dosing an aquarium easy and simple for all aquarium plant keepers using a small aquarium. I would highly recommend both these products and as a result both are one of top sellers in FishCove Aquatics.
