Sponge Pre-Filter Benefits

THE USE OF SPONGES FOR POWER (HOB) FILTER PRE-FILTERS; ADVANTAGES/BENEFITS:



The simplest way to perform sponge Pre-filtration is using a specifically designed Sponge Prefilter such as the Filter Max (pictured to the left)






However an aquarist can use a standard Aquarium Sponge Filter (such as the Hydro Sponge #2 shown in this picture) attached to the Aquarium Power Filter as shown in the picture to the left (please click the picture to enlarge for a better view).







Here are just a few of the Advantages/Benefits:

• Provides additional Bio Filtration, often vastly more than the bio capacity of most Aquarium Power Filters
• Allows for aquarium Power Filter media/cartridge changes/cleanings without the worry of loss of important nitrifying bio bacteria
• Prevents weak, sick, baby fish from being sucked into or stuck on the filter intake.
• Allows for much of the un-eaten fish food from being immediately removed from the water column during feeding. Fish can often “graze” on these food particles on the sponge that would otherwise be taken into the power filter (Mollies especially love to graze on these particles)
• Increases Bio capacity of the aquarium
• Easy to clean. Just rinse and squeeze in used tank water
