Clinofish - what it is and how to use it

Clinofish is a specific type of Zeolite mineral exclusively mined in South Africa by Pratley.

It is a direct substitute for fish pond “silica sand” filter media.

Clinofish has a negative charge and will absorb positively charged ions from the pond; ammonia is positively charged and it will remove ammonia. When removing ammonia you will have fewer algae in your pond as the algae feeds of ammonia. Clinofish removes the feed source of the algae.

Because of its honeycomb surface structure Clinofish attract and trap extremely fine dirt particles and algae directly onto their surfaces and not just between the grains like ordinary sand. You should notice a considerable difference to the water clarity after just one day of use. Clinofish filters down to +/- 3-5 microns whereas sand filters between 20-30 microns.

Also, unlike ordinary filter media such as gravel or sand, the surfaces of Clinofish particles are not smooth and therefore have large surface areas. Clinofish is therefore an extremely effective biological filter media for maximum colonization of useful bacteria, which is good for the fish.

Clinobrite can be reactivated by removing the Clinofish from the filter and placing it overnight in a strong salt solution (15-20% solution). The salt – Sodium Chloride, which is also positively charged, will push out the ammonia from the structure of the Clinofish. The next morning just rinse the Clinofish under fresh water and place in the filter again and the Clinofish will be ready to absorb Ammonia again.

Alternatively just scatter the Clinofish on your lawn or flowerbeds, being loaded with ammonia, which is a fertilizer, it will ensure you have a beautiful garden.

Clinofish will also backwash more effective than ordinary sand. The reason is: Clinofish is much lighter than sand, which means when backwashing the media will be lifted and cleaned from the bottom up – unlike normal sand which sits heavy in the filter. A bag of Clinofish only weighs 25 kg, whereas the same quantity of sand weighs 40kg’s.

Commonly asked questions:

What happens if I medicate with salt, will the Clinofish not dump ammonia back into the pond, which could kill my fish?

This is a common myth, it is perfectly fine to medicate with salt, as long as you do not medicate above 5% solution. Clinofish will only release ammonia proportional to the amount of salt added.

How many bags will I require for my pond?

A normal fish pond makes use of a “2 bag-sand filter” you will also require 2 bags of Clinofish. Per volume the Clinofish is the same quantity, it just weighs much less than sand. If you have a 3 bag-sand filter you will require 3 bags of Clinofishand so on.

How often should I backwash?

You still need to backwash frequently; backwashing with Clinofish will be more effective because the media is lighter than sand and the Clinofish will be lifted from the bottom up in the filter which means you do not have to backwash that long and will not waste your pond water.

How long does the Clinofish last and when should I reactivate the product?

It depends on the size of your pond and the amount of fish you have in the pond, but normally you should replace or reactivate the Clinofish every 1 to 2 years. It is also good to smell the water, if you smell ammonia it means the Clinofish is not removing the ammonia anymore and you should reactivate or replace.

When building a new pond where should I install the Clinofish filter?

The Clinofish filter normally goes before the UV light. The UV light should be the last thing the water passes through before going into your pond.
