Amazing Product, Swift Delivery
The product as described. Seriously i was surprised how easy to install and the hustle Free experience of have the test results just a look away. No strips no risky chemical touching. It will be inside the aquarium and you can monitor all the time the levels. Swift delivery also. Well recommended.

Really liked this product for a ‘not super experienced yet’ aquascape wannabe. Feel I can check easily for the ammonia potential in the tank now and be confident to trust this little tool for keeping my tank safe and healthy.

No encontré tiras que midan amoniaco. Este dispositivo sirve perfecto, en cuanto hay picos de amoniaco lo puedes observar.

Après avoir eu des pics de nitrites (NO2) surprise été 2022 lors des fortes chaleurs,ayant entraîné une mort éclairé d’un magnifique baryancistrus chrysolomus que j’adorais (en deux heures…) 😭. Suite à ce désastre, je cherchais un moyen de prévenir ce genre de soucis pour mes bacs les plus sensibles, sans avoir à passer par de continuels tests d’eau en goutte qui sont longs et dont les réactifs ne détectent PAS les NH3- (les ammoniacs les plus toxiques). Celui là les teste et permet donc d’avoir l’esprit tranquille lorsque l’on sait que les aquariums sont des écosystèmes fragiles…. Je ne peux que le recommander, il est fiable et économique (dure UN AN). La réputation de fiabilité de Seachem n’est plus à démontrer 🥰

8 am happy to have it. It is a safe guard for my little aquatic friends. Some will say it doesn't work because their drop test gives an other result. I did my researches. The drop test shows results for Ammonia and Ammonium together. Ammonium isn't toxic bu ammonia is very. The sensor of Saechem react to only Ammonia not to Ammonium. It is an important thing to know.

This product is awesome, it has stopped my obsession to need to test everyday, I’m fairly new to fish keeping 6 months in, My tank is fully cycled but the need to make sure the perimeters were perfect everyday was still there, Spending alot of money if api test, I’ve had this in my tank for 3/4 weeks and I love it, I know it’s only measured free ammonia but as that is the worst for the fish so that’s what I’m going to worry about, I water change every week anyway, What I will say I’ve noticed is during the day it will be at the safe level, once the lights are off over night it moves to the first warning alert level, On googling this is completely normal as my lights are off which stops the plants doing their thing, as soon as the lights come on it goes back to safe level, I did do a strip test after a couple of days then haven’t again highly recommend this for peace of mind,
