Using Matala Sheets in Different Filter's for more Nitrifying Bacteria to Grow on.

The amount of Matala® needed will vary with each pond and design. Some filters are too small for the pond, but you can improve filter performance with Matala®. Some hobbyists may be open to upgrading their system to a larger filter size.

In general, we can shoot for these guidelines:

When deciding how many sheets of Matala® are needed for your pond, think 1,2,3,4. This is the number of sheets per 1000 gals depending on your fish load. The fish load really determines the volume of any media required. Many hobbyists' filters are too small for the fish load. Your pond could still function reasonably well because ponds are very resilient and manage to adjust to high fish loads even with small filters. However, a pond with a high fish load and a small filter will need to increase maintenance and care. You will likely have bigger algae problems and fish health issues if your filter is too small.

For R-Matala rolls use the following guidelines:
R-24 use 1 roll per 1000 gallons for light fish loads or water gardens.
2 rolls per 1000 gallons for medium fish loads.
3 rolls per 1000 gallons for heavy fish loads.

R-36 use 1 roll per 2000 gallons for light fish loads or water gardens.
2 roll per 2000 gallons for medium fish loads.
3 rolls per 2000 gallons for heavy fish loads.

R-48 use 1 roll per 4000 gallons for light fish loads or water gardens.
2 rolls per 4000 gallons for medium fish loads.
3 rolls per 4000 gallons for heavy fish loads.
