Filters

A filtration system is a combination of different stages put together to accomplish one result which is good water quality for your Koi fish.

Understanding Filters

There are three  stages in a koi pond filtration system, Namely MechanicalBiological, and UVclarification. First is a mechanical filter, A mechanical filter is there to remove all visible debry  in the water namely fish waste and all other particles  that maybe floating around in the water. After the mechanical filter collects all this waste it is then extracted from the filter through back wash which is perfomed usually once every week or so depending on your load. There are many types of Mechanical filters out there, some use sponges some use matting and some use filter media but they are all designed to achieve one thing and one thing only which is to clean your water.

Biological Filter

This is the second stage on a pond filtration system. This part of the filter is there to do the invisible part of work  that we cant really see but also very vital to your pond water quality. After your mechanical filter has collected all your fish waste and all the dirty from your pond it gets stuck in your filter before it is eventually extracted via back wash. During this period all the collected waste  is going to decompose and will start to produce AMMONIA which is a very toxic gas that can do harm  to your fish if the levels rise too high, But not to worry thanks to the biological filters that are there to take care of that. Biological filters consists of the good bacteria that helps convert Ammonia (NH3) to Nitrite (No2) which is also toxic to fish if left to rise ,then to last product Nitrate (No3) which is not as toxic as first two.There are products sold that can help activate your Biological filter. 

UV light

A uv light is the last stage on your  filter system also very vital in terms of water clarity. A uv helps to kill the single-celled  free flowing algae within your pond water that usually makes your water green if it left to florish. The  way it works is your water passes through a uv unit of which it is then exposed to the  ultraviolet light to kill the algae.

Types of filters

Pressuried Filters

Bubble bead filter is  a pressurised mechanical filter system. It looks exactly like a good old sand sand filter but works completely different. It uses plastic beads instead of sand which means less strain on your pump. It comes with an air blower for backwash which means it uses  mostly air to backwash instead of water, Very economical and easy to maintain. 

Koi filters  use koi sand or clino fish inside which does a very good job to clean your water.  

Pre filter

Brush filters use brushes on the inside. Ideal to install just before your normal sand filter to relief it of some of  the strain. To clean just pull brushes out and rinse with a horse pipe These come in two sizes 800mm and 400mm.

Pressuried bio filter with a uv

biological filter combo comes with a uv clarifier. 

Pressurised Bio filter

Pressurised biological filter comes after your mechanical filter. A bio filter helps with the convertion of the toxic stuff that we cant really see but can be very deadly to fish. These are ammonia and nitrites so it is very crucial as part of our filtration system. 

10l bio filter

Pressurised biological filter comes after your mechanical filter. A bio filter helps with the convertion of the toxic stuff that we cant really see but can be very deadly to fish. These are ammonia and nitrites so it is very crucial as part of our filtration system. 

Low Pressure filters

Low pressure systems were designed mainly to save electricity and because they are open they do not need a strong pump to run them. This simply means a small and energy saving pump is required to operate them. A low pressure system can be set in two different ways either pump feed gravity return or gravity feed pump return. These systems can be easily run by low power consuming submersible pumps. 

Filter Chambers

These are built- in filter chambers can be built depending on the size of your  pond. These are mostly gravity feed pump return systems.

50 liter Gravity combo

This is an example of pump feed gravity return. Designed to handle from about 5000 liters of water to around 8000 liters. Easy to install and maintain.

Gravity combo

An all in one filter designed for small ponds from 3000 liters to about 4500 liters. It is a combination of Mechanical, Biological,and Uv clirifier in one. they come in two sizes 25l  and 15l.

Gulp Filters

Designed to handle 20 000 liters of water. Gulp filters come as a set of Mechanical and Biological, All using super actiflow bio media in both of them. The difference between the two is Mechanical is static to make sure it trapes all debry that floats aroung in the water and Biological is a moving bed with help of an air pump which pushes oxygen all the time this is to keep your good bacteria alive. Easy to maintain designed to make koi hobby enjoyable.

UV Clarifiers

Uv pond Clarifier   A uv helps to kill the single-celled free flowing algae within your pond water that usually makes your water green if it left to florish. The way it works is your water passes through a uv unit of which it is then exposed to the ultraviolet light to kill the algae
