Aquarium Water Treatments


All devoted fish owners want a thriving and healthy aquarium that’s a paradise for their aquatic pets and looks simply stunning in their homes. To achieve this, you’ll need to treat your tank with aquarium water treatments from time to time, or when required.

From enhancing water quality to cleaning chlorinated tap water and preventing algae to providing your fish with essential nutrients, we have everything you need for a healthy aquarium environment.

Our helpful experts can help you find the best aquarium water treatment for your needs –

Why do I need a fish tank water treatment?

Aquariums are a vibrant display that can bring an element of life and energy to your home. However, if yours isn’t maintained correctly with effective aquarium water treatments, it can become a very unhealthy and unbalanced environment for your beloved fish and aquatic plants!

A fish tank water treatment can:

  • Improve water clarity
  • Balance your pH levels
  • Reduce disease
  • Increase oxygen levels
  • Remove harmful toxins
  • Clear murky and green water


Envii Fish Tank Treatments

We stock an extensive range of cleaning formulas for aquariums, tailored to fix specific problems that may occur in your fish tank. 

Additionally, our exclusive aquarium water treatments should make up part of your regular tank water maintenance, helping to keep it clean and safe for fish.


Improve your water clarity

Is your water turning green, murky or cloudy? Try Aquarium Klear – this natural treatment uses beneficial bacteria to boost water clarity and remove harmful toxins from your fish tank. It’s also a handy biological gravel cleaner, reducing how frequently you need to clean your gravel.

Fix your tank pH levels

If your tank’s pH levels are unbalanced, it can impact the health of your fish by causing stress, disease and even death.

After testing your water parameters and finding that the pH is too high or too low, you’ll need to add a treatment to make your aquarium safe for your fish again.

A simple and effective way to bring biological balance to your aquarium is with our Aquarium Equaliser. This treatment stabilises the pH level in your fish tank between a healthy 7.5 pH and 8.5 pH, and buffers additional parameters including KH, GH and ammonia levels.

Make your tap water safe

The tap water we drink is treated with chlorine, which is harmless to us but dangerous for our fish. But that doesn’t mean we can’t use tap water to fill up our tanks – you just need to treat it with a de-chlorinator aquarium water treatment to remove any chlorine and chloramine from your fish tank.

Our Aquarium Chlorine Klear uses natural and beneficial Vitamin C to condition your water to remove chlorine and reduce fish stress.
