Yes, and if you mean no stock but ammonia, yes again. You might be better off doing a water change if you have life in tank though. If you dose this you will have to monitor nitrite and nitrate cycles. **Q: Im new...will this kill off my invert food sources or hurt them in any way?** A: It will not kill your invert food source. It’s bacteria that’s beneficial to your aquarium **Q: Noob question how much of this do I use on a 32 gallon biocube? It’s a new tank I can’t find any measuring cups for ML anywhere n my town** A: Once your tank has been fed regularly for a few days either with out without fish to start the bacterial cycle, add half during the first week and the other half during the 2nd. Add a small amount after water changes is also a good idea for upkeep. Buy 2 bottles. **Q: how long did it take for this product to bring down nitrite levels?** A: I wouldn't use this product as a means of nitrite reduction. Live rock will do a much better job of that. I use this product as a means of adding biodiversity to my tank. It did nothing for nitrate levels. ## Frequently Bought Together - Brightwell Aquatics MicroBacter7 Complete Bioculture for Fish Tank or Aquarium - Populates Biological Filter Media for Saltwater and Freshwater Fish - Aquarium Water Treatments, 135.25 fl oz - Brightwell Aquatics MicroBacter Clean - Microbial Culture & Enzyme Blend Fish Tank Cleaner - Cleans Live Rock Surfaces for Saltwater Fish Habitats - Aquarium Water Treatments, 135.25 fl oz --- ## 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/336262166-microbacter7-bacteria-and-water-conditioner-for-fish-tank-or-aquarium](https://www.desertcart.tn/products/336262166-microbacter7-bacteria-and-water-conditioner-for-fish-tank-or-aquarium) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-09*
