Seachem Ammonia Alert is a convenient and innovative device that will stick to the side of the aquarium. Ammonia can be lethal, even at a low level and cause fish health problems and even death. This is especially common in a new or heavily stocked fish tank.
It uses a colour changing system to denote the concentration of ammonia. It will be green when dry and change once in the water:
- Yellow : Safe
- Light grey: Alert, some detection of ammonia at around 0.05mg/l
- Dark grey: Alarming level around 0.2mg/l
- Blue: Level of ammonia is toxic at 0.5mg/l
This unit works continuously so you can always monitor the levels within your aquarium. It is suitable for use in both fresh water and marine tanks, and as it lasts over 1 year, your tank is well covered.
It's a good idea to keep a good Ammonia Remover on hand too, to resolve the problem if it arises.
