It cycled my 5 gallon tanks in about 2 weeks and my 10 gallon in about a month. It says it cycles up to 15 gallons, so I only used half in each 5 gallon tank. Please use this and let the tank finish cycling before buying or adding your fish. The ammonia spike it will cause will most likely kill your fish. Fish will suffer during the process so a fish less cycle is best. It is not an instant fix to throw your fish in right after adding it, but it will activate the nitrogen cycle without using any other form of bacteria to get it going. Once the nitrite and ammonia reading are zero, and you start seeing nitrates, you just change about 20% of the water, and you are ready to add the fish. Just be patient. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great product to cycle your tank! *by C***. on Reviewed in the United States on August 14, 2017* I used this to cycle a new tank with 6 fish in it. I worked wonderful and the ammonia never spiked. I use it for water changes and adding new fish.I was really amazed and relieved. You do need to be sure you add enough. The quantity you need to cycle a new tank is smaller on the package. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Four Stars *by D***X on Reviewed in the United States on January 28, 2018* Best product. Unbelievable pricing, another words at a freshwater aquarium fish store, I paid $12.99. going through Amazon Prime, I only paid 6.99. listen up people, get on board with Amazon Prime. --- ## 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.tn/products/26541276-marineland-bio-spira-freshwater-bacteria-for-aquariums-3-38-ounce](https://www.desertcart.tn/products/26541276-marineland-bio-spira-freshwater-bacteria-for-aquariums-3-38-ounce) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-24*
