Who this product is marketed towards:

  • Customers using tap water

  • Chlorine is bad for plants. Some people let their tap water “offgas” the chlorine – and in sunlight this should work. This is a tedious and time consuming process though, filling buckets with tap water and placing them outside for days to get rid of the chlorine.There has to be a better way. With Chlorine Killer, just add it to the water and it’s ready for use.
  • Chloramine is really bad for plants and has no easy way to be remediated. This is different from chlorine. Some consumers don’t even know about chloramine. It’s very common in fish waste and tap water. Many municipalities treat water with Chloramine too. This is great at keeping water safe to drink, but bad for your plants.
