The Truth Most Fishkeepers Never Hear
If you're a beginner, intermediate hobbyist, or even an advanced aquarist running planted tanks or monster fish aquariums, you’ve probably used tap water hundreds of times.
It feels harmless.
It looks clean.
It tastes clean (to humans).
But for your fish?
It can be slow poison.
Across India, tap water is treated with chlorine, chloramines, heavy metals, pesticides, and industrial residues to make it safe for drinking. These chemicals keep humans safe but they damage delicate gills, destroy beneficial bacteria, and trigger fatal stress in aquarium fish.
Many fishkeepers don’t realize that every water change, even a small one can expose your fish to:
- Gasping for air at the surface
- Burnt gills
- Damaged slime coat
- Erratic swimming
- Long-term stress
- Reduced immunity
- Sudden unexplained deaths
This is where Sunken Garden Anti Chlorine becomes your aquarium’s first line of defense.
But before we explore the solution, let’s understand the science, the real risks, and the experience that inspired the most powerful anti-chlorine solution crafted for Indian aquariums.
The solution? Sunken Garden Anti Chlorine instantly removes chlorine and chloramines, making water safe for your fish in seconds.
Why Tap Water Is Harmful for Aquarium Fish

1. Chlorine: The Silent Killer
Chlorine is added to municipal tap water to kill bacteria and pathogens.
But when chlorine enters your aquarium:
- It burns gill tissue
- It destroys beneficial bacteria
- It irritates fish eyes and skin
- It causes fish to gasp or stay inactive
Even 0.02 mg/L of chlorine can stress fish.
Most Indian tap water contains 100–300% more than what fish can tolerate.
2. Chloramines: Even More Dangerous
Many Indian cities now use chloramines, a mix of chlorine + ammonia.
They last longer in water and are much harder to neutralize.
Chloramines cause:
- Long-term stress
- Slow poisoning
- Ammonia spikes after breakdown
- Severe gill burns
Regular conditioners often neutralize chlorine but cannot break chloramines effectively.
Sunken Garden Anti-Chlorine is specifically formulated to neutralise both instantly.
3. Heavy Metals in Tap Water
Your local tap water may contain:
- Lead
- Copper
- Arsenic
- Aluminium
- Zinc
For fish, even trace amounts can cause:
- Neurological damage
- Appetite loss
- Sudden death
4. Tap Water pH Shock
India's tap water pH varies massively between 6.5 to 9.5.
Fish introduced without conditioning face:
- Rapid breathing
- Stress stripes
- Immunity crash
- Instant death (in sensitive species)
How a Simple Mistake Cost Me My Fish
I’ll never forget the day I lost some of my most beloved fish. My team and I had just set up a brand-new display tank, carefully selecting rare, vibrant fish. Excited, I filled the tank with water straight from the tap, treated it with our usual conditioner, and introduced the fish. But within hours, something was terribly wrong.
The fish were gasping, their movements sluggish. Some were swimming erratically, while others sank to the bottom, barely moving. My heart sank as I realized my mistake—I had forgotten to neutralize the high chlorine levels in the new tap water.
Despite immediate water changes, I lost several fish that night. It was a painful lesson, one that drove us to create Sunken Garden Anti Chlorine, a powerful, fast-acting solution that instantly removes chlorine, chloramines, and other toxic chemicals from tap water, ensuring this never happens to another fishkeeper again.

Common Mistakes Indians Make With Tap Water (Must Avoid)
❌ Adding tap water directly during top-ups
This instantly exposes fish to chlorine.
❌ Relying on “tank maturity”
Even old tanks need anti-chlorine during water changes.
❌ Believing “fish will adjust”
They don’t. They suffer silently.
❌ Using untreated water for rinsing filter media
This kills beneficial bacteria.
