Tips for choosing the right filter
There are a handful of different types of pond filters available for purchase. They vary in their function and each serve a unique purpose. A small pond can be maintained by a single filter unit, if properly installed and cared for. Combining units in a more complex system will safeguard further against problems, helping to ensure the pond water is always healthy and looks clean.
In-pond pre-filters – also known as filter boxes – are designed to work in small pond systems, mechanically removing small particles from the water. They attach to the intake of the pond pump and provide mechanical filtration through a sponge filter.
Skimmers. This is a large box mounted outside the pond liner at the water level. Strictly mechanical in nature with no bio-chambers they continuously draw in surface water to catch large debris before it settles to the bottom of the pond. Skimmers also house the pond’s water pump, and provide excellent aeration of the water.
Pressure Filters. These filters can be found in small to medium-sized ponds, using pressure to force water through a sponge filter that collects small debris particles. Due to the pressurization they can be placed anywhere in the water system setup even hidden by burying in the ground.
Waterfall filters – also known as gravity return filters – have a significant amount of biological filter materials in them, making them best suited for small to medium ponds with fish. They are not pressurized and need to be placed above the waterline to feed water back into the pond.
With many options available for purchase, it’s incredibly easy to construct an efficient filtration system to meet all of a small pond’s needs. So, which one is the best filter for your small pond?
TetraPond Submersible Flat Box Filter
A simple, in-pond pre-filter, the TetraPond Submersible Flat Box Filter is an ideal filter for smaller ponds up to 500 gallons and works best with pumps having a capacity of 200 to 2000 gallons per hour. It mechanically removes dirt and debris using coarse and fine foam pads helping to prevent clogging of the pond’s pump and/or fountain heads.
Water is drawn into the pump and passes through the coarse and fine foam mats to remove particles. The pump then draws water in from the filter and discharges it into the pond providing beneficial aeration to the pond water and aquatic life.
Best Choice Products 4000 Liter Pressure Bio Filter with UV Sterilizer Light
Incredibly efficient this newer to the market product is capable of filtering up to 12,000 liters per hour of pond water and is easy to maintain. This pressure filter is suitable for 2500 gallon ponds with a normal fish level and up to 1500 gallon ponds if the fish load is high.
It is not designed to be submerged in water and does not include a pump. The Best Choice Products 4000 Liter Pressure Bio Filter with UV Sterilizer Light includes an integrated 13W UV clarifier and UV lamp indicator to reduce algae concentration in water.
TetraPond Bio-Active Pressure Filter with UV Clarifier
Designed for ponds up to 1500 gallons in volume, the TetraPond Bio-Active Pressure Filter with UV Clarifier provides mechanical and biological filtration to assist in maintaining clean, healthy pond water. An easy to use filter design provides an open profile to the bio-activator for improved cleaning and enhanced water flow.
Large surface areas on the bio-active components allow for increased bacteria colonization, to improve the breakdown of harmful ammonia and nitrites into plant-safe nitrate. The TetraPond Bio-Active Pressure Filter with UV Clarifier has an integrated UV clarifier that works to control algae with ultraviolet light. This pressure filter is also designed with a backflush valve for fast cleaning.
Laguna Skimmer Filter
The Laguna Skimmer is a simple, heavy-duty surface skimmer and filter that provides essential mechanical filtration for small ponds. Install it at the water line to draw in surface water; the filter will catch large debris before it settles to the bottom of the pond and begins to decompose. With its rugged construction the Laguna Skimmer Filter is made for durable performance that will withstand the elements.
The inside of the filter compartment is designed with a removable skimmer net for fast and easy cleaning and maintenance. Laguna products are carefully field tested and evaluated by a knowledgeable Quality Assurance department to ensure reliable, effective products that provide years of performance.
TetraPond Waterfall Filter
Quickly and easily create beautiful waterfalls while adding extra aeration in a garden pond using this TetraPond Waterfall Filter. This waterfall filter is easy to install and blends well into the surrounding landscape or can easily be hidden with rocks and other pond decorations. An easy to assemble filter provides both mechanical and biologic filtration (an included mesh bag allows for the addition of 6-8 liters of bio-activators).
The TetraPond Waterfall Filter will filter small ponds up to 1000 gallons in volume. Pond water is pumped to the bottom of this filter, a unique concept when compared to other pond filters, and then rises upward through a fiber mat which collects dirt and debris particles. The water then flows through lava rock or the added bio-activators and exits the TetraPond Waterfall Filter via an extra long spillway where the waterfall action is created.
Small ponds add an incredible aesthetic element to a backyard or landscape. Keeping the water clear and healthy for aquatic life is an essential aspect of maintaining a pond but is easier to do with the right filtration system. Money budgeted and spent on a high quality, effective filter will save much headache and problem solving down the road allowing the homeowner more time to enjoy the beautiful water feature!
