Seachem Alert pH and Ammonia for Freshwater

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

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

Don’t throw it away, it took a while to get going

I bought for my new setup and are working perfect I saw these in my local fish store and I’d say they are an excellent buy easy to install the size is good really good quality and awesome value for money water clarity doesn’t come in to it your just keeping an eye on ammonia and ph levels I highly recommend them for beginners and experienced fish keepers

I have used the ammonia test before and was pleased with it , this pack contains a ph alert as well , good value , I can recommend it

I would give 0 stars for this item if I could as I wasted my money. I have ordered second one to change it into new one and the new one is looking bad different colours on the sensor pad which doesn't give reliable reading. Really disappointed as it's not cheap...the PH one was fine .

I purchased these mainly to satisfy my curiosity, they have had mixed reviews. After a few weeks use i can confirm in my experience that the pH alert is useless, it never changed & bore no resemblance to my actual tanks pH using other tests. The Ammonia Alert however does seem effective. I have tested it in tap water and over ammonia vapour- it clearly works. What is does not do is measure TOTAL ammonia like the dip stick tests and liquid reagent tests. It measures NH3, toxic free ammonia, and this far more important. The indicator tallies with the calculated free ammonia using the appropriate scientific calculation based on total ammonia, pH and temperature. I shall continue to use it as an early warning device.

These are a brilliant idea and so helpful, I have them in 2 tanks now.

Must have in your tanks! Helps so much just a glance at the tank and you know if there is anything to worry about

Love these. Nice to walk by tank and at a glance be reassured to couple key water parameters. I’ve tested against my liquid drops and the results were spot on. I keep a set in all my tanks. One thing I’ve noticed is they seem to lose accuracy if allowed to dry or have air exposure like during routine water changes. I am going to start placing at the bottom of tank instead of near top where I have been using them.

Excelente producto, sumamente práctico y funcional para mantener el acuario dentro de los parámetros ideales, yo los compré para un ajolote que requiere mucho cuidado en la calidad del agua y son una excelente ayuda visual para el monitoreo del agua

Bonjour, Je fais confiance à ce test qui répond à mon attente pour mes aquariums de Discus. Le 1 er test je l'ai comparer avec d'autres tests et il répond bien, donc il a ma confiance et le second acheté que je test actuellement également répond correctement. Je pense que c'est fiable pour le ph et surtout l'alerte d' amoniac mortelle pour mes Discus.

No regrets.
