Aquarium Glass Inline CO2 Bubble Counter - Bubble Shape

The glass CO2 bubble counter is an important part of any aquarium and will help you get the correct CO2 setup as it help you estimate the amount of CO2 going into your aquarium just by counting the bubbles. This is critical as a overdose of co2 will raise your ph valve and cause stress to your fish, while under dose of CO2 will slow down the growth of your plants which is against the idea of adding CO2.

Recommended set up is:

  • Fill the bubble counter with water.
  • Connect C02 tubing from the regulator with non return valve
  • Connect non return valve to bottom of bubble counter with silicone tubing (place non return valve close to bubble counter)
  • Connect the top of the bubble counter with silicone tubing, then connect with diffuser

If you have a solenoid, place it under/below the non return valve. Therefore the set up should be: solenoid > non return valve > bubble counter > diffuser
Compatible with pressurized Co2 tanks & DIY yeast bottles.

Bubble Counter Size:

  • Outside Diameter: 24mm
  • Height: 88mm

    We offer FREE* Shipping on EVERY** order – WORLDWIDE. It’s really that simple. However, if you simply can’t wait for your order, or you prefer the re-assurance of tracking it until it reaches you, we have different options available to you.

    Standard and Express delivery services are available for most of the countries that we ship to. Once you add products to cart, you'll be able to calculate and see the available delivery services.

    Tracking is available on some Standard Delivery services and on all Express Delivery services. You will receive a shipping confirmation email from the warehouse with a tracking link for your parcel so you can follow its journey.

    Shipping costs are calculated automatically at the checkout page when both the destination and delivery service are selected.

    Our carriers deliver during normal business working hours and may require a signature on receipt, so we suggest your order is delivered to an address where someone will be available to accept it.

    Your order will be sent out via the most suitable carrier, dependent on size and weight.

    In most cases, any customs or import duties are charged once the parcel reaches its destination country. The exception to this is for parcels being sent to Brazil or India on our Standard Delivery service.

    Any charges on a parcel must be paid by the person receiving the parcel (this also applies to retail & wholesale customers).

    CO2Art Ltd has no control over these charges and we can’t tell you what the cost would be, as customs policies and import duties vary widely from country to country. It might be a good idea to contact your local customs office for current charges before you order, so you are not surprised by charges you were not expecting.

    Once your order has arrived in your country, it will be passed on to an internal postal service, according to standard delivery procedures.

    If you are not in when your parcel arrives, the carrier will leave a card telling you where it is. It might be left in a safe place or there will be details on how to pick up your order or rearrange delivery.

    Please be advised that on any public holiday dates in your country, deliveries will not be made. In this instance, please expect your order to arrive the next business day.

    Delivery times for Free and Priority shipping are not guaranteed and may vary depending on location and local postal office efficiency.

      - Please check any safe areas outside your address that the courier may have left your parcel.
