Seachem Alerts Combo Pack, 6 Months

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.

Read the description, guys. These tests can take several days to be fully effective, and the ammonia alert only monitors the more toxic form of ammonia, free ammonia or NH3, as opposed to NH3 and NH4, which is what other ammonia tests detect. I would not call it a substitute for regular testing of all water parameters, but it's a great way to know quickly if there's a serious problem in your tank, like a dead fish in a hidden corner or a mass bacteria die off. I'd consider the ammonia test alert a necessity for serious aquarium keeping. Get one for every tank, no matter how small. The picture was taken 30 minutes after I placed the test in a dead daphnia colony. It works, guys. I fully expect it to help me avoid future daphnia colony crashes.

Pretty handy at a glance info

As many elders have said this tester for ammonia is highly inaccurate and will not notify you in time for gradual changes. I confirmed the inaccuracies with two other brand test kits which both indicated levels that this tester did not. I do not recommend.

This unit is just for emergency notification, not to actually track ammonia in your system. I have it up in a corner so it is not in the way of viewing, Cant say either way how well it works since my ammonia has been at 0 since I put it in, but I do look at it every time I walk by the tank which is what it is meant for, you see the little yellow circle change colors and you need to get on top of the ammonia spike right away. Should be noted the Ammonia alert works for both fresh and salt water, the other monitor in this pack is Freshwater only, so I gave it to my mom to use in her fresh planted tank. In the end I feel it is worth the few bucks to have an emergency ammonia notice system on your tank.

Perfecto para mi pecera de 37 galones, buen precio y muy buena calidad

These things really are great to have. The ammonia one is the best. I currently have 3 sets on 3 of my tanks. I'll probably buy more for my other tanks. Here's the but... The PH one claims to work for 3 to 6 months.. Well, which is it? 3 or 6? This is a pretty big window. I would say one month, tops. Let me explain something about aquariums for those who don't know. If your PH drops below a certain amount, your beneficial bacteria dies. Which means your cycle can crash. You really want to stay above 6. Even 7 is good. If your cycle crashes, you get an ammonia spike. And your fish can die. This is why these 2 alerts are good together. These 2 things are probably the most important thing to monitor. And most test strips and kits don't test for ammonia. The ones that do, like the master kit, are expensive and a real pain in the butt to use. You don't want to have to test all the time. And it's wonderful to wake up every day & have a look see at the alert to get a basic idea of what's going on. However, back to the PH one. I had it for maybe a month in a 55 gallon. It was reading low. So without thinking about it, I got some baking soda and mixed it into Jugs and raised the PH. Next day it was still reading low on the alert. So I tested the PH myself to find I had raised the PH to an unbelievably high level.. I then had to lower the PH. You'll see in the pictures I'll post the 55 is saying the PH is much lower than the other 2 tanks. I can assure you that the PH is in fact the same as the other 2. So the PH alert is almost useless after about a month. I really wouldn't put any stock into what they say, ever. Always do a 2nd test before trying to adjust the PH. I didn't the 1st time. I won't make the mistake again. As for the ammonia one, I read somewhere that they only measure toxic ammonia. This is a really good thing. Because chemicals like Seachem Prime will detoxify ammonia. And any other test will show the ammonia regardless. Having a test that only sees the toxic ammonia is amazing to me. Because at the end of the day, that's all you need to know about. I hope this review help you out. They work to a certain degree. But always test with a test kit before making any adjustments.

When im setting up my fish tanks I purchase these. They help me make sure my parameters are right. I have other products from the same brand. Very happy with my purchase

love 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.

Dura poco per quel che costano. Meglio le strisce a questo punto
