The CO2 tablets from ISTA are a great way to provide Co2 to your aquarium plants.
- Fast and easy way to provide your aquarium plants with CO2;
- Will dissolve gradually;
You will notice the micro Co2 bubbles start to diffuse from the tab. Tab will last for 2 hours.
- 1 ISTA CO2 Tablet for every 5.5 gallons of water.
For heavily planted aquariums, we recommend using a Co2 cylinder.
This does NOT replace injected Co2 from a cylinder supply.
