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. Review: Saved my plants. - 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. ## Features - Causes serious eye irritation. - Causes skin irritation. - May cause allergy or asthma symptoms or breathing difficulties if inhaled. - May cause an allergic skin reaction. - May cause respiratory irritation. - Contains one (1) API CO2 Booster Freshwater Aquarium Plant Treatment 473 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 | |---------------|-------| | ASIN | B004GY9ZYI | | Allergen Information | Apple Free | | Best Sellers Rank | 5,480 in Pet Supplies ( See Top 100 in Pet Supplies ) 61 in Aquarium Water Treatments | | Brand Name | API | | Country Of Origin | USA | | Customer Reviews | 4.6 4.6 out of 5 stars (4,654) | | Global Trade Identification Number | 00317163055793 | | Item Form | Liquid | | Item Type Name | Aquarium Plant Treatment | | Item Weight | 1 Pounds | | Liquid Volume | 16 Fluid Ounces | | Manufacturer | API | | Manufacturer Part Number | 579E | | Model Number | 579E | | Pet Type | Fish | | Target Species | Fish | | UPC | 317163055793 | | Unit Count | 473.0 millilitre | ## Product Details - **Brand:** API - **Item form:** Liquid - **Item weight:** 1 Pounds - **Liquid volume:** 16 Fluid Ounces - **Number of Packs:** 1 ## Images ![API Co2 Booster Freshwater Aquarium Plant Treatment 16 oz Bottle, Brown - Image 1](https://m.media-amazon.com/images/I/51h8OP2BxmL.jpg) ## Available Options This product comes in different **Pattern, Size** options. ## Questions & Answers **Q: Does this help green hair Algae in tank?** A: It helps all things that photosynthesis but generally plants need more then algae so it should help your plants out compete the algae - depends on the balance of your tank if you have a good light and lots of plants should help. You need to add this daily about an hour or two before lights go on. In my experience hair algae linked to light being on too long - you can get stuff to get rid of the hair algae - or get more plants or even better a co2 system **Q: If this reduces algae, is it ok for CAE and nerite snails??** A: dont think it is for reducing algae but it is fine with snails. **Q: Could this be used in soil for indoor plants ?** A: Probably not ....the doasage in a 90 litre tank is 1 mm ...in soil Probably half a bottle ...so wouldn't be cost effective. Try phostregen plant food ... **Q: Is this good for carpet grass?** A: I tried co2 and found it made no difference what so ever. I occasionally use plant fertiliser but my plants seem to do well without. Grass seems to grow well if the temperature is right, too warm and it dies.
