Review: Fantastic. - Works fantastic. Review: What it said on the tin - Did what it was supposed to do ## Features - 【SAFELY INCREASES CARBONATE HARDNESS】: Pond fish require a safe and stable pH to remain healthy. As pond water ages, fish waste and other organic matter uses up the carbonate hardness (KH) that provides this safe and stable pH. If left unchecked, a low KH can lead to unstable water quality, a sudden drop in pH and serious illness in fish. - 【BOOSTS KH LEVELS IN YOUR POND】NT Labs KH – Buffer Up replenishes these essential minerals leading to a safe and stable environment. - 【EASY TO USE】: To work out the required dosage for your pond, simply calculate the volume of your pond in litres (length x width x depth (in cm)/1000) or alternatively, use our Online Dosage Calculator. Dissolve the powder in a bucket of pond water before adding to the pond. - 【USE IN CONJUNCTION WITH NT LABS TEST KITS】: Use NT Labs Hardness Test Kit to measure the KH of the pond water. Always keep the KH above 6 dKH for optimal water quality. KH – Buffer Up can also be used to provide additional carbonate hardness where tap water is naturally low in hardness minerals. - 【 SUITABLE FOR ALL POND KEEPERS 】: The ease of use of Koi Care KH Buffer Up means it is perfect for use by beginners and seasoned pond keepers alike. - [ MADE IN BRITAIN ] : Proudly formulated and manufactured in the UK to strict quality, environmental and safety standards, delivering exceptional product reliability you can trust. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00A4CJB68 | | Best Sellers Rank | 17,224 in Garden ( See Top 100 in Garden ) 112 in Water Garden & Pond Treatment | | Brand | NT Labs | | Brand Name | NT Labs | | Customer Reviews | 4.6 out of 5 stars 197 Reviews | | Included Components | Powder | | Item Form | Powder | | Item Highlight | Carbonate hardness minerals increase the alkalinity reserve of pond water to prevent sudden catastrophic pH crashes. | | Item Type Name | Pond Fish Food | | Item Weight | 1.5 Kilograms | | Item form | Powder | | Item weight | 1.5 Kilograms | | Liquid Volume | 1.5 Kilograms | | Liquid volume | 1.5 Kilograms | | Manufacturer | NT Labs | | Manufacturer Part Number | 00427 | | Model Number | NT Labs | | Target Species | Fish | | UPC | 733809004275 | | Unit Count | 1500.0 gram | | Unit count | 1500.0 gram | ## Product Details - **Brand:** NT Labs - **Item form:** Powder - **Item weight:** 1.5 Kilograms - **Liquid volume:** 1.5 Kilograms - **Unit count:** 1500.0 gram ## Images ![NT Labs Koi Care KH Buffer Up pH Stabiliser (1.5kg) - Image 1](https://m.media-amazon.com/images/I/61ADpCwPpdL.jpg) ![NT Labs Koi Care KH Buffer Up pH Stabiliser (1.5kg) - Image 2](https://m.media-amazon.com/images/I/71Io3i4xDBL.jpg) ![NT Labs Koi Care KH Buffer Up pH Stabiliser (1.5kg) - Image 3](https://m.media-amazon.com/images/I/81WOLCYeLkL.jpg) ![NT Labs Koi Care KH Buffer Up pH Stabiliser (1.5kg) - Image 4](https://m.media-amazon.com/images/I/81JueCyXP3L.jpg) ![NT Labs Koi Care KH Buffer Up pH Stabiliser (1.5kg) - Image 5](https://m.media-amazon.com/images/I/71XK--Pge7L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic. *by G***D on 16 August 2026* Works fantastic. ### ⭐⭐⭐⭐⭐ What it said on the tin *by Y***K on 22 July 2026* Did what it was supposed to do ### ⭐⭐⭐⭐ Pond treatment *by P***N on 6 November 2023* Happy with purchase and the delivery time ## Frequently Bought Together - NT Labs Koi Care KH Buffer Up, Increases Carbonate Hardness of Pond Water, Maintains Pond Water Quality, Provides the Optimal Habitat for Your Fish and Other Pond Life, 1.5kg - NT Labs Koi Care GH Minerals Up, Increases General Hardness of Pond Water, Maintains Pond Water Quality, Provides the Optimal Habitat for Your Fish and Other Pond Life,1.5kg - Evolution Aqua Pure Pond Bomb – for Crystal Clear Healthy Water, Treats up to 20,000 litres --- ## 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.pt/products/53170341-nt-labs-koi-care-kh-buffer-up-ph-stabiliser-1](https://www.desertcart.pt/products/53170341-nt-labs-koi-care-kh-buffer-up-ph-stabiliser-1) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-28*
