Shrimple Matten Filter - 20 Gallon Long

20 Gallon Long Matten Filter Matten Filters are the best filtration for freshwater shrimp keeping and breeding. The amount of surface area the filter creates makes a great feeding surface for shrimp and baby shrimp. Microorganisms thrive on the sponges surface making it an ideal place for shrimp to find natural food.  Key Features: Creates the ideal Water Circulation for a Shrimp Tank Huge Surface Area for Beneficial Bacteria to Thrive Inexpensive Running Cost Low Maintenance and Upkeep Perfect for Larger Breeding Projects Small PPI Prevents Shrimp from Getting Stuck in the Foam 2 to 4 times the Surface Area of Typical Sponge Filters Item Specification: Foam Type: Black Reticulated Foam Pores per Inch (PPI): 35 Size: 12.25 x 11.5 x 2 Items Included: Matten Filter and Lift Tube Items not Included: Airline Tubing or Air Stone  More Information: The Matten filters here at Flip Aquatics are made out of the same material as 99% of the sponge filters on the market. It is a durable foam that is completely shrimp and fish safe. Recently, we began experimenting with Matten filters in our shrimp breeding tanks. After just a few short months, we saw a huge change in the health of our shrimp and the behavior. Shrimp breeding picked up and baby shrimp survival rates started to rise. Here are the two reasons we feel Matten Filters are the best filtration for freshwater shrimp tanks: surface area and flow. The Matten filter provides a whole wall of filtration. The surface area is usually 2 to 4 times as large as a standard sponge filter. This is great for colonizing bacteria, reducing risk of clogs and it provides a surface where baby shrimp can scavenge. The filter will be littered with biofilm and micro organisms that are essential to the survival of baby shrimp. The flow created by the lift tubes on the Matten filter provide the ideal amount of flow for a freshwater shrimp tank. It creates an ideal current that flows from top to bottom. By having the bottom of the lift tube close to the bottom of the tank, it is essential moving water from the bottom of the tank to the top of the tank. This creates great circulation throughout the whole tank.
