Make no mistake about it-filters do some of the key heavy lifting in your aquarium system. While it is easy to understand the life and death impact a bad pump can have on your water`s overall health and oxygen level, many aquarium owners are still unclear regarding how important a good filter is for their aquarium`s health. Let`s put it this way, the filter acts as your aquarium system`s kidney. Not only does it physically segregate debris, it also cleans the water through chemical means. Debris segregation is important because you wouldn`t want uneaten food or excrement to accumulate. Not only does this look bad, it also smells bad and can decompose into more toxic compounds. Which brings us to the most important role of the filter-it handles threats to your water`s health which you can`t see.

Chemical compounds like ammonia and nitrates pose quite a threat to your aquatic pets. A good filter uses chemical filtration to knock out this threat. To work properly, filters need an outlet tube. Just like with any piece of equipment that gets heavy use, this tube might wear out or might degrade with age. Thankfully, you can easily swap out your magnum filter`s outlet tube with the Marineland Outlet Tube with Diffuser for Standard Magnum from Pet Store.
