Give your aquatic plants the extra support they need with ISTA Water Plant CO2 Tablets.
Designed for convenience and ease of use, these tablets are a practical CO2 supplement for planted aquariums. As they slowly dissolve, they release CO2 into the water to encourage healthier, stronger, and more vibrant plant growth. Use 1 tablet for every 20 litres (5.3 US gallons) to deliver around 5 mg/L of CO2.
