Fine with my shrimps *by on Reviewed in the United States August 7, 2026* Great product has helped weeken hair algea and now all my shrimp are going crazy on it. Will see how it does with the black beard algea. Has really helped one tank near a sunny window with its algea issues. Will definitely keep a bottle of this on hand. ### ⭐⭐⭐⭐⭐ It could be my imagination *by on Reviewed in the United States April 15, 2026* I read all the reviews that said they aren’t sure if it really does anything but their plants are doing great and I have came to the same conclusion. I have several planted tanks and the ones that I use this stuff in have been having new growth at rates I have never seen before. I have heavily planted with no co2 gas injected into the systems. I will be buying this stuff for as long as they sell it. It could still be a scam but i really don’t think so ### ⭐⭐⭐⭐⭐ It works! *by on Reviewed in the United States March 31, 2026* I was skeptical to say the least. I've used leaf zone and that doesn't really do anything. I even tried a yeast based co2 injection which made bubbles but didn't seem to do anything either. So I decided to give this product a whirl...For one example- I've had java and christmas mosses in my tank for months and haven't done anything except fade away. Once I started adding Co2 booster, I actually saw growth! Same with my dwarf hairgrass. Other plants don't seem that affected, but no worse. Shrimp and fish are safe. So, I'd say this product is effective. I don't use it every single day- maybe I remember every third day. ## 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.gr/products/6814412-api-co2-booster-freshwater-aquarium-plant-treatment-8-fl-oz](https://www.desertcart.gr/products/6814412-api-co2-booster-freshwater-aquarium-plant-treatment-8-fl-oz) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-25*
