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 ### ⭐⭐⭐⭐⭐ Liquid Co2 *by J***E on September 8, 2022* ### ⭐⭐⭐⭐⭐ Daily use in Planted tanks. *by K***R on November 6, 2025* ### ⭐⭐⭐⭐⭐ You need to know what it is! *by 9***S on September 16, 2023* ## 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.at/products/748558805-api-co2-booster-8-ounce-by-api](https://www.desertcart.at/products/748558805-api-co2-booster-8-ounce-by-api) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-22*
