​The filter mat below the debris basket is the second stage of the skimmer. The mat is designed to handle any debris that finds its way past the basket. The mat will not need maintenance as frequently as the basket, since the basket will remove the majority of debris from the water.
 
The water reaching the pump should be relatively free of any large debris, thanks to the debris net and filter brushes on the skimmer, and, if you have a Pondless Waterfall, the fact that the water has to pass through layers of gravel in the basin.

Note: The filter mat may have a slot cut into it so that it fits around the discharge pipe. Install the filter mat correctly so the slot fits around the discharge pipe. Skimmer filter mats are designed to last for about two years. Filter mats may be discolored and appear dirty and old, but will work just fine in your skimmer and BIOFALLS filters, or MicroFalls. Replace old filter mats if they begin to tear or fall apart. ​

​On occasion, you may see a reduction in the water flow over the waterfall in Carlisle, Mechanicsburg, Harrisburg and Hershey PA . This could be a sign that it is time to clean the filter screen on the bottom of the pump. This process should take no longer than five minutes. Simply unplug and remove the pump from the skimmer or Pondless Waterfall Vault and physically remove any debris found on the bottom of the pump. You may also want to physically remove any debris with your hands that may have found its way to the bottom of the skimmer or Pondless Waterfall Vault, where the pump sits.

​There are two basic types of filtration. The frist one in Mechanical or all also referred to as skimmers. The second types is biological it absorb ammonia, and turn nitrites into nitrates, which are less dangerous (this mean it take all the bad stuff from the fish out).

Aquascape offers an extensive line of BioFalls® biological waterfalls filters designed to help you create a beautiful, low maintenance water garden.  A biological style of filter provides a home for beneficial bacteria to grow.  These special strains of bacteria that are added to the water garden are highly effective at breaking down and removing wastes from the water, such as ammonia, nitrogen, decaying plant debris and fish waste.  All of this waste, if not properly filtered, can become harmful to fish and cause significant water quality issues.  One of the biggest challenges with most biological filters on the market is they are difficult to hide and are often an eyesore that takes away from the overall beauty of the pond.  The Aquascape Biofalls®, unlike traditional biological filters, are actually hidden into the landscape.  The Biofalls® can be buried into the ground to create the beginning of a stream or raised to create the start of a beautiful waterfall.  The top of the filter can be filled with aquatic plants and accent stones allowing the filter to be completely camouflaged into the landscape.  Once the Biofalls® is installed, you could be standing right next to it and not even know it is there.​The ones under 10,000 gallons are the most popular in Mechanicsburg, Harrisburg and Hershey.

A wetland works just like a biological filter, but instead of creating a waterfall; it creates an area in your pond thick with naturally-filtering plants, as well as rocks and gravel, which provide a surface for bacterial colonization … nature’s perfect filters. So a wetland, while naturally beautiful and pleasing to the eye, is a great filtration method, and will help keep your water looking crystal clear. The ones over 10,000 gallons are the most popular in Mechanicsburg, Harrisburg and Hershey.

​One of the greatest things about wetland filtration is that it can be used with almost any system. But will it fit in with your pond? Do you have to have a lot of space to construct a wetland?  There are no size limitations because it acts as your biological filtration. The plants, rocks, and gravel act as the filtration media, similar to what you see in nature.
