| I use the Nexus filters in my ponds and am very pleased with them. You might want to consider this type of filter as it has both a mechanical component and a fluidized K1 biological component. Plus it's extremely easy to clean. The downfall is it's a little pricey. If money is an issue, then I would consider a few 55-gal fluidized K1 barrels. But first you need a mechanical component to separate out the large wastes/particles. Hope this helps. |
