Media

Within the last several years, the water garden and koi pond hobby has seen some major advances in understanding of system designs and pond ecology. This evolution of understanding has progressed from an era based on simple techniques and filter systems and has evolved to the current "high tech" era based on gadgets and accessories. 

 Matala®  is the first media which is actually made for the express purpose of filtering koi ponds. Matala handles the high solid waste levels associated with koi. It is easy to clean. The media also acts as a substrate for biological filtering, a home for the good bacteria. A high surface area per cubic foot is necessary. The media does not plug up too quickly, or the bacteria would go anaerobic. Matala media provides good movement of highly oxygenated water throughout the entire filter.

A good biofilter media requires what is called interstitial spaces. These are the small open spaces in between the media where bacteria can "fill up" in a safe and slimy bacterial matrix. Bacteria love interstitial spaces. The perfect media would let go of the dirt during cleaning but sustain the bacteria attached. Many of these requirements are contradictory to one another. Water will always travel the path of least resistance; so this media has to be positioned in a filter so the water does not go around it. This requires a somewhat rigid type material in order to be wedged in place. Another benefit to being rigid is that the media can be self supporting. The material has a very slight bouyancy this way it will not end up at the bottom of the filter tank. Matala Media consists of a series of 4 filter pads with progressive densities that can be used separately or together to complement one another. They are in 4 different colors so they can be easy to differentiate. Each pad has it’s own unique structure lending itself to a different job in filtration.

The various densities can be used in sequence or separately for unique filtration requirements. This is one of the greatest characteristics which Matala has to offer. No other media on the market can perform this step-wise filtration. Matala effectively separates large particles to small and still maintains a very aerobic and free flow of water without channeling.


How to Cut Matala Filter Media

Matala® is rigid and yet still slightly pliable.

It will hold it's open 3 dimensional internal structure even if purposely crushed.

It is easy to cut. Use a hole saw to cut circles for pipework. Use a jig saw with a fine tooth blade, or 8" long sharp carving knife for free-form shapes. You can also use band saw, with a very fine tooth blade, or turn the blade and use the backside as knife, Use a masonry blade turned backwards on a circular saw.

Matala only needs to be 10 inches to 20 inches deep in the filter at the most (some designs will only require 3" to 6"). Stand the Matala vertically on edge and the 39" wide will make 4x 9.75" pieces; the 48" wide will make 4x 12" pieces. Cutting this way will reduce waste.

Determine how many sheets of matala will work for the application.

Get dimensions and determine overall volume of filter tank.

Subtract at least 3" to 4" of water space above and below your media for good water distribution.

What is the available volume in cu.ft for Matala?

Divide cu.ft by 1.6 equals number of full sheets required.

Does this volume coincide with recommended guidelines; 1,2,3,4?

Determine how to cut the Matala with the least waste.

Do you want to lay the sheets flat ? Cut Matala to inside dimensions to fit a little tight, 1/8 inch too big is OK.

Do you want to stand the Matala on edge? This usually gives the least waste.


Matala/Hakko Air Pumps

Oxygen is the most important element for life. All life revolves around the availability of Oxygen. In aquatic environments like fish ponds, oxygen is the single most limiting factor for success. All aquatic life forms demand oxygen. From the fish down to the bacteria any body of water has what is called an “oxygen demand”.

Of all the essential elements in water, oxygen is also in the shortest supply.
Ponds and lakes gain oxygen in two ways:
Photosynthesis by algae and plants.
Atmospheric oxygen is transferred into water at the surface of pond.
Photosynthesis may produce sufficient oxygen for very low fish loads but is inconsistent due to the fact that at night algae and plants remove oxygen through the process of respiration. Most of the ponds and lakes we deal with have higher than natural fish loads and require additional oxygen to maintain a clean and healthy environment.

Matala/ Hakko air pumps can be used to create a huge column of bubbles or “air lift” rising from the bottom of a pond or lake. This brings oxygen depleted water to the surface where the bubbles burst and create tremendous surface turbulence, circulation and aeration. Hakko air pumps used in this manner will literally breathe life into your pond or lake.
Hakko pumps are compact, affordable, energy-efficient and very, very quiet (less than 38 decibels!)!
Hakko units utilize linear- motor theorem to reduce power consumption during full operation. Units are extremely quite utilizing spectrum analysis technology in order to decrease any mechanical noise.

No oil needed for lubrication making the Hakko easy to maintain.These are the best large air pumps available today.
36 month warranty through the manufacturer.

Repairing The Matala/Hakko Air Pumps

The diaphragm kits are simple to install. They include the diaphragms and parts necessary to rebuild your air pump. Refer to the owners manual for directions on the proper replacement procedure.

The magnet is the part that moves back and forth with the diaphragm. It holds the diaphragm secure and vice a versa. Typically the magnet is very long lasting. However if you run the air pump with bad diaphragms for extended periods you could wear down the magnet. If you open the motor for repair and you find dust or small metal particles you may need to replace the magnet. Always inspect the magnet for wear and tear when you replace your diaphragms. They are very easy to replace.


STANDS 

Stands assist in keeping the Air Pump safe and secure in a well ventilated and dry location. Mount to a wall or other solid flat surface.


THE AIR MANIFOLD

The air manifold is very important for two reasons. It gives the ability to send air to various areas within the aquarium, pond or filter and allows the venting off of potential back pressure.  (Caution these mainifolds are for smaller aquarium type installations.)


Matala Air Diffusers

These air disc diffusers and weighted bases are very easy to install and the best way to complete your aeration system. Our rubber membrane disc diffusers are the best on the market. They are made of high quality EPDM rubber for use in the waste water treatment industry. They are very suitable for the aquaculture and water garden industries. These disc diffusers are the lowest back pressure diffuser made and only exert less than 6 inches of back pressure on the system. The high quality base is designed to be modular with 8 configurations available so you can add on to your system if needed
