And ammonia Review: Seachem Alert pH and Ammonia for Freshwater - i use these all the time and i have found that they work well proving you are not using prime with it as well because if you do they can give a wrong reading the colour changes in the middle disc when there is a problem with the water this packet you get 2 you get PH and Ammonia and these ones are for freshwater so if you are wanting saltwater these ones wont work - there is a saltwater option though value for money on this item is good because you are getting them both and it keeps the water quality stable and good quality and it warns you there is an issue before it gets too bad Review: They’re affordable, practical, and give you continuous reassurance that your water is safe - I’ve been using the Seachem pH Alert and Ammonia Alert in my freshwater tank for several months, and I’m really pleased with them. They’re simple, reliable, and make life much easier when it comes to routine checks. Both sensors give a clear visual reading that changes colour depending on the levels, so you can see at a glance if anything’s off. The Ammonia Alert is especially useful for catching problems early. It’s great peace of mind knowing I’ll spot a spike before it becomes serious. The pH Alert is just as handy, and both have stayed accurate and easy to read under normal lighting. Many recommend the liquid test kits for precise readings every so often, but these monitors mean I don’t need to test constantly. They’re ideal for keeping an eye on things day to day. Installation took seconds. Just rinse, stick it inside the tank, and you’re done. No batteries, no mess, and no guesswork. They also look tidy and don’t spoil the view of the tank. Overall, I’d highly recommend the Seachem Alert pair to any fishkeeper. They’re affordable, practical, and give you continuous reassurance that your water is safe ## Features - Seachem Sensor technology - Continuous monitoring of pH in fresh water - Marine and Freshwater ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004HSQSLG | | Battery Description | Lithium-Ion | | Battery description | Lithium-Ion | | Best Sellers Rank | 31,006 in Pet Supplies ( See Top 100 in Pet Supplies ) 9 in Aquarium Water Pump Accessories | | Brand | Seachem | | Colour | Yellow, Green, Blue | | Control Method | Push Button | | Control method | Push Button | | Country of Origin | USA | | Customer Reviews | 4.3 out of 5 stars 2,827 Reviews | | Global Trade Identification Number | 00000116001205 | | Included Components | Sensor | | Item Weight | 5 g | | Manufacturer | Seachem | | Model Number | 28155 | | Mounting Type | Floor Mount | | Mounting type | Floor Mount | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 75319 | | Power source | Battery Powered | | Sensor Technology | pH and ammonia | | Shape | Rectangular | | Size | 1 Count (Pack of 1) | | UPC | 781163338147 000116001205 | | Unit Count | 1 count | ## Product Details - **Brand:** Seachem - **Material:** Plastic - **Tank volume:** 30 Litres - **Special feature:** Lightweight - **Item weight:** 5 g - **Shape:** Rectangular - **Specific uses for product:** Active - **Style:** Classic - **Colour:** Yellow, Green, Blue - **Included components:** Sensor ## Images ![Seachem Alert pH and Ammonia for Freshwater - Image 1](https://m.media-amazon.com/images/I/712B4+LYuHL.jpg) ![Seachem Alert pH and Ammonia for Freshwater - Image 2](https://m.media-amazon.com/images/I/51m1fhNDM3L.jpg) ![Seachem Alert pH and Ammonia for Freshwater - Image 3](https://m.media-amazon.com/images/I/816BgkCD83L.jpg) ![Seachem Alert pH and Ammonia for Freshwater - Image 4](https://m.media-amazon.com/images/I/61Fd5wce+KL.jpg) ![Seachem Alert pH and Ammonia for Freshwater - Image 5](https://m.media-amazon.com/images/I/51MJ2WjtljL.jpg) ## Questions & Answers **Q: When when are you getting a niterite alertare you going to get a nitrite alert** A: I am very sorry to tell you "THE BEST THING TO DO WITH THIS ITEM IS PUT THEM IN THE BIN" !! mine said different readings constantly STICK TO STANDARD TEST KITS ... **Q: Has anyone had a similar problem as both of my cards havent changed colour since puttimg it in the tank 3 hours ago, followed instructions ?** A: You should not really expect much change in colour unless you have a really bad water quality, I found hardly any noticeable change. I used for over 6 months and I'm sure it stayed a pale yellowy shade. **Q: What size is each of these cards?** A: 2 inch high 1inch wide ruffly **Q: Will the ph reader work for malawi cichlids with seachem cichlid salt?** A: Should do, I use it malawi tanks although I don't use seachem chichlid salt any more because of its high price. Bicarb and epsom salts much cheaper. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Seachem Alert pH and Ammonia for Freshwater *by D***T on 16 February 2026* i use these all the time and i have found that they work well proving you are not using prime with it as well because if you do they can give a wrong reading the colour changes in the middle disc when there is a problem with the water this packet you get 2 you get PH and Ammonia and these ones are for freshwater so if you are wanting saltwater these ones wont work - there is a saltwater option though value for money on this item is good because you are getting them both and it keeps the water quality stable and good quality and it warns you there is an issue before it gets too bad ### ⭐⭐⭐⭐⭐ They’re affordable, practical, and give you continuous reassurance that your water is safe *by G***S on 15 October 2025* I’ve been using the Seachem pH Alert and Ammonia Alert in my freshwater tank for several months, and I’m really pleased with them.

As for the pH, its hard to tell the colours apart as all the oranges look similar the same. And they don't follow any order. Its not like it gets gradually darker the higher the pH. Like 6.8 will be dark 7 will be lighter 7.2 will be darker 7.4 lighter. Kind of all over the place. Also the actual orange the senror changes to doesn't really look like any of the oranges on the sensor to me. So best I can guess is its somewhere between 7 and 7.6 and I'm happy with that, it always seem to stay the same colour so at least I can tell its stable ## Frequently Bought Together - Alerts Combo Pack, 2 Monitors,2 Count (Pack of 1) - API FRESHWATER MASTER TEST KIT 800-Test Freshwater Aquarium Water Master Test Kit, White, Single, Multi-colored - PAIZOO Fish Tank Digital Thermometer Accurate LED Display to ±0.9°F Tank Thermometer Aquarium Temperature Measurement Suitable for Fish, Axolotl, Turtle or Aquatic --- ## 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.hu/products/48977302-seachem-alert-ph-and-ammonia-for-freshwater](https://www.desertcart.hu/products/48977302-seachem-alert-ph-and-ammonia-for-freshwater) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-08-11*
