This will keep your fish strong and vibrant, as well as preventing disease. It is important to test your aquarium water weekly to verify good quality in addition to a bi-weekly partial water change of no more than 25% to help reduce toxic buildup, remove debris the filter missed, and replenish the oxygen available to fish. Feed your fish twice daily only the amount of food they can eat in 2 to 3 minutes depending on the species. Some fish such as bottom feeders and algae eaters will need up to 30 minutes to 2 hours. Overfeeding & low quality nutrition cause unconsumed food and more excrement which cloud water and raise harmful ammonia levels, possibly leading to fish loss. Take time to observe fish and the water temperature to ensure they are active & healthy. An aquarium is a closed environment and in order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness and even loss. The 5 common water quality parameters are Ammonia, Nitrite, Nitrate, and pH - all of which may vary over time and all are invisible to the eye which is why it is important to test weekly with API MASTER TEST KITS or API 5-IN-1 TEST STRIPS. It is also a good time to add API STRESS ZYME to keep your aquarium & gravel clean. In a closed aquarium environment there are no natural rivers or streams to carry away debris and other waste materials. It is important to renew 25% of the aquarium water every two weeks. When you change the water, it is important to know that tap water contains chemicals that make it safe for us to drink but harmful for fish, therefore add a water conditioner such as API STRESS COAT. It is important to change your filter media & clean gravel monthly, however in doing so it can disrupt the fragile ecosystem of your aquarium. Use API QUICK START to strengthen it with ‘beneficial’ nitrifying bacteria that will naturally consume toxic compounds and help prevent fish stress. Also recommended when starting a new aquarium or changing the water. ## Features - Contains one (1) API CO2 BOOSTER Freshwater Aquarium Plant Treatment 237 ml Bottle - Promotes plant growth in freshwater aquariums - Adds essential carbon in a form plants can absorb from the water - Can be used alone or with a CO2 system without altering aquarium pH levels - Use daily in order to ensure lush, vibrant aquarium plants ## Technical Specifications | Specification | Value | |---------------|-------| | Allergen Information | Apple Free | | Asin | B003NXRSRY | | Best Sellers Rank | 7,523 in Pet Supplies (See Top 100 in Pet Supplies) 88 in Aquarium Water Treatments | | Brand Name | API | | Country Of Origin | USA | | Customer Reviews | 4.6 4.6 out of 5 stars (4,694) 4.6 out of 5 stars | | Global Trade Identification Number | 00317163035795 | | Item Form | Liquid | | Item Type Name | Aquarium Plant Treatment | | Item Weight | 0.6 Pounds | | Liquid Volume | 237 Millilitres | | Manufacturer | API | | Manufacturer Part Number | 579C | | Model Number | 579C | | Number Of Items | 1 | | Number Of Packs | 1 | | Pet Type | Fish | | Target Species | Freshwater Plants | | Unit Count | 1 count | | Upc | 317163035795 | ## Product Details - **Brand:** API - **Item form:** Liquid - **Item weight:** 272 g - **Liquid volume:** 237 Millilitres - **Number of Packs:** 1 ## Images ![API CO2 Booster Plant Treatment for Freshwater Aquariums, 237 ml Bottle - Image 1](https://m.media-amazon.com/images/I/71LkgXxQH6L.jpg) ![API CO2 Booster Plant Treatment for Freshwater Aquariums, 237 ml Bottle - Image 2](https://m.media-amazon.com/images/I/81gEffaQ8VL.jpg) ![API CO2 Booster Plant Treatment for Freshwater Aquariums, 237 ml Bottle - Image 3](https://m.media-amazon.com/images/I/91b75qOdIBL.jpg) ![API CO2 Booster Plant Treatment for Freshwater Aquariums, 237 ml Bottle - Image 4](https://m.media-amazon.com/images/I/91cpK3Yde6L.jpg) ![API CO2 Booster Plant Treatment for Freshwater Aquariums, 237 ml Bottle - Image 5](https://m.media-amazon.com/images/I/81G5AjWgwVL.jpg) ## Available Options This product comes in different **Pattern Name, Size Name** options. ## Questions & Answers **Q: Can this be used for hydroponic systems?** A: We do not recommend any of the API products that are for any fish or plants meant for human consumption. **Q: Is this safe to use with Bettas and glass catfish?** A: I would suggest to treat the plants in a separate tank without fish (1 gallon) to be in safe side. Once the plant is healthy you can use it in the fish tank. **Q: Does this come in pond strength?** A: This does not come in larger amounts for ponds. **Q: My tank is bright neon green and it's been running for a week with no light. It's also planted, will adding the CO2 booster help my algae bloom?** A: Using API CO2 Booster will help the plant thrive and reduce algae growth. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by on Reviewed in the United Kingdom 29 September 2025* It works and helps my plants stay fresh and green. It had no effect on my fishes. It is better to buy a bigger bottle as it’s cheaper than the small ones and it’s better if you have a big fish tank like I do plus it’s easy to use. Great quality would recommend. ### ⭐⭐⭐⭐⭐ Saved my plants. *by on Reviewed in the United Kingdom 19 August 2023* I've only ever run low tech tanks with a few super-easy plants but I went a bit mad with my newest tank and splashed out on a bigger variety. All seemed well until my hygrophilia, limnophila and ludwigia super-red started rotting from the ground up. Never really felt the need to try co2 booster but this pushed me to do so. I noticed the difference after literally 3 or 4 days, and all of my plants have really bounced back. They're no longer losing leaves, and the new growth looks super healthy. Now that I've seen what this can do I'll probably always use it in the future. Highly recommended. ### ⭐⭐⭐⭐ CO2 *by on Reviewed in the United Kingdom 29 August 2025* Good product, if I stop to using few days straight algae appear… ## Frequently Bought Together - API Co2 Booster Freshwater Aquarium Plant Treatment 8 Fl oz Bottle - API LEAF ZONE Freshwater Aquarium Plant Fertilizer 8-Ounce Bottle - API ROOT TABS Freshwater Aquarium Plant Fertilizer 0.4-Ounce 10-Count Box --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/53602111-api-co2-booster-plant-treatment-for-freshwater-aquariums-237-ml](https://www.desertcart.sk/products/53602111-api-co2-booster-plant-treatment-for-freshwater-aquariums-237-ml) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-18*
