Filters

To support aquatic life, every pond will require some level of filtration. There are mainly two types- mechanical and biological. Through both forms, the pond will process a variety of nutrients in the pond, including fish waste, uneaten fish food and accumulated debris. Whether choosing from an external or submersible, pressurized or gravity fed system- selecting the right filter for your pond should not be underestimated.

Filters
Pressurized Filters

With a pressurized filter, water from the pond is pumped into the filter where it exits under pressure. These units can be installed anywhere around the pond and can be buried for easy concealment. Most have backwash capabilities making cleaning a breeze. Most come with integrated UV clarifiers.

Pump & Filter Kits

These kits take the guesswork out of selecting the correct pump and filtration combination for new or existing ponds. Buying a filtration kit is simple and provides the best overall value.

Professional Filters

These systems are designed to run with external pumps and ponds with high fish loads. Patented media supports bacterial growth while backwash systems separate the waste from the media sending it out the waste line.

Submersible Filters

Nice for smaller ponds where external filtration is not an option. These units generally incorporate filter pads where the flow is often run to a fountain head or small waterfall. Submersible filters are also available as all-in-one kits, including pump and sometimes UV clarifier.

Waterfall Filters

Waterfall Filters or, Bio-filters, are generally installed at the top of a waterfall, these are some of the most cost effective and low maintenance systems available. Water from the pond is pumped into the filter via a pump. The water then flows through the filter overflowing from a spillway and eventually returning to the pond via gravity. Waterfall filters can accept substantial flowrates, house a variety of filtration media, and can be buried.

Gravity Fed Filters

Some of the most cost effective and low maintenance systems available. Water from the pond is pumped to the filter where it then flows through the filter- overflowing and returning to the pond via gravity. These filters must be kept above the pond- usually installed at the beginnings of waterfalls.

Rotary Drum Filters (RDFs)

These premium Rotary Drum Filters (RDFs) effectively remove micro debris, most models filtering particles down to 75 microns! As dirty water enters the filter, it passes through a rotating drum that physically separates debris from the water column, flushing it away automatically.

All Filter Pads & Media

Looking for mechanical or biological filtration media? You'll find it here. We carry filter pads, bio media such as BioBalls and even large filter mat sheets and rolls you can cut at home.

Sea Side Aquatics Bakki Showers

Bakki Showers utilize a unique design where water is pumped to the top of the unit and dispersed over ceramic biological filter media (sold separately). As water flows through and around the media, it becomes infused with oxygen and undergoes biological filtration.

Sea Side Aquatics Moving Bed Chambers

Moving Bed Filters provide extraordinary surface area for beneficial bacteria colonization, ensuring superior water quality for koi health. When combined with an RDF, they provide outstanding biological filtration to perfectly compliment the mechanical filtration from the RDF.

The Oase Clear Water Guarantee is your assurance of clear water down to three feet, a guarantee like no other. Precisely engineered and matched components function in concert to remove not only suspended solids for excellent clarity, but toxic wastes as well, assuring high water quality. Filter pumps designed to pass solids pick up and deliver fish wastes to multistage filters. Filter foams of varying densities strip out solids and particulates. Beneficial bacterial colonies remove ammonia, nitrite and nitrate, eliminating nutrients in the water. Finally, water is bathed in ultraviolet light in an EPA-certified clarifier to further inhibit the growth of algae. You will be able to read the 1" mark on a measuring tape three feet below the surface, guaranteed.

Aquascape Professional Grade Bio-Falls Waterfall Filters provide the most filtration and highest water flows in the market. Made from durable rotational molded polyethylene ensuring maximum strength. Biological filters are positioned to create the beginning of the waterfall in your pond. The filter uses bacteria to break down pond wastes, converting them into less harmful compounds that can be used as aquatic plant fertilizers. Water enters via flexible pipe located near the base of the unit. The water then flows from the bottom to the top, traveling through filter media and Bio-balls (optional) housed inside the unit. The filter media helps with the removal of fine to medium-sized particles. As the filter fills, it overflows and cascades over its waterfall lip, cascading down rocks that have been set to create a waterfall. The waterfall creates aeration for your pond, assisting in the circulation and health of the water.
