A pH of 0 is the most acidic, while a pH of 14 is the most alkaline. Water with a pH of 7.0 is considered "neutral". Different geographies have different tap water conditions with different pH levels, while fish require a specific pH level to thrive. API PROPER pH 8.2 Freshwater Aquarium pH Stabilizer automatically sets and stabilizes the pH level in freshwater aquariums to 8.2 which is perfect for saltwater, brackish water, reef and African Cichlid aquariums. API PROPER pH 8.2 Freshwater Aquarium pH Stabilizer also removes toxic compounds from tap water such as chlorine, neutralizes chloramines, detoxifies heavy metals, and adds electrolytes, making tap water safe for fish. Use this aquarium treatment when setting up a new aquarium, adjusting pH, or changing water. pH in an aquarium can fluctuate due to fish waste, uneaten food and addition of tap water. It is recommended to test water for pH weekly. With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium.

Will reccomend it to anyone ### ⭐⭐⭐⭐⭐ Works well *by Q***N on November 7, 2024* Get the water in spaces if you’re running a low ph. ### ⭐⭐⭐⭐⭐ Perfect to raise saltwater PH to 8.2 *by T***N on June 26, 2018* I am sometimes having hard time to maintain 8.2 PH on my reef aquarium. Some salt types don't rise the PH as they supposedly do and keep the water PH around 7.8 which is not healthy for Reef. I found this very helpful to maintain PH between 8.2 and 8.4. Highly recommended for saltwater hobbyists. ## Frequently Bought Together - API PROPER pH 8.2 Freshwater Aquarium Water pH Stabilizer 210 g Container - API Stress Coat Aquarium Water Conditioner, Fish , 473 ml Bottle --- ## 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.co.uk/products/3828825-api-proper-ph-8-2-freshwater-aquarium-water-ph-stabilizer](https://www.desertcart.co.uk/products/3828825-api-proper-ph-8-2-freshwater-aquarium-water-ph-stabilizer) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-23*
