UV Filters All Use Alfagrog or Supra Filter Media
Pond Supplies Product Review ... Fish Mate Compact Pond Bio Filter for garden fish ponds specified for up to 5,000 gallons volume.
This Fish Mate pond biofilter is still very small in size despite being capable of handling the biological load from a pond of up to 5,000 US gallons .... it is one of the very few types of pond filters (maybe the only type in the USA) to contain the world class highly effective and efficient pond filter biomedia called Alfagrog. This is what creates the huge bio degradation capacity of this Fish Mate Pond Filter. Any biological filter removing such large loads as this will need extra oxygen to maintain high biofilter efficiency and this is why I say possibly reduce capacity to a maximum of 4,000 US gallons unless you add supplemental air.
Until very recently I was not aware that Alfagrog was used in any American pond filter and was very pleasantly surprised when is stumbled across the Fish Mate pond filters and especially when I saw the low price of Fish Mate pond filters. The reason I was not aware is that Alfagrog goes by another name in the USA, Supra. Here's a picture of Alfagrog which I have sold for 10 years here in South Africa.
This
is what you will find in this filter ... this is what really counts. The secret to this little marvel's
success is the Alfagrog. It is a highly porous ceramic filter media specially
created for bio filters in the fish farming industries. Depending upon the size
of the Alfagrog particles the area for bacteria colonization can be up 100 times
that for most types of plastic filter media ... whether they be tubes, balls, or
other fancy shapes.
This Fish Mate pond filter data ... Pond's volume .... claimed up to 5,000 US gallons
Discharge by gravity, needs to be above ground. Does not contain UV, can handle a maximum flow rate through pond filter of 2,400 galls per hour ... you can by-pass some water if necessary and I would suggest you do not pump this amount of water through this pond filter. If you try to pump too much through this Fish Mate Pond Filter you risk overflowing the filter and draining your pond (this applies to any gravity fed filter) .... here's another tip. Always position your filter so that if it does happen to overflow then the water can run back into the pond.
Dimensions ... 24*17*21 inches (yes that small so easy to hide)

Pond filter biomedia choice inside a fish pond filter is critically important. A fish pond filter purifies pond water at the interface with the biomedia. This is where the bacteria colonies reside and do their bio filter work. The better the biomedia the smaller the diy pond filter needs to be. Building a pond filter is easy.
SSA (specific surface area) in sq.m. per litre of different pond filter biomedia for a home made pond filter is shown below. A high number is best! If an SSA is 1 then theoretically an SSA of 8 will provide surface to hold 8 times as many bacteria inside a pond filter. The same relationship applies to gallons of biomedia.

Pond filter biomedia
All biomedia in fish pond filters or bio filters of any type can be classified according to its specific surface area (SSA). The higher the SSA the more probable is it that the biomedia will be more effective in a fish pond filter. SSA refers to how much surface area per unit volume of a type of media is available for colonisation by bacteria inside fish pond filters. You can now see how you can easily choose biomedia for your diy pond filter.
For products like simple plastic tubes inside a diy pond filter SSA can be calculated easily because it is a smooth surface and a simple shape. In fact if you do the calculation the SSA is about 1 sq metre per litre of biomedia. In other words if a fish pond filter is filled with plastic tubes then for every litre used about 1 sq. metre of surface is provided for colonisation by the bacteria. Alfagrog will provide between 40 and 100 time MORE area than this in the SAME volume space
