8 Reasons Why Undergravel Fish Tank Filters Are Great
What will definitely guarantee that the fish in your aquarium are healthy and vibrant, above all things, is water that is crystal clear. And the only pierce of equipment capable of producing the pristine environment is the fish tank filter. It is the most vital tool for every fish enthusiast and along with a fish tank heater, recreates the environment from where the fish originated.
One filter that has stood the test of time is the undergravel filter. Though it is mostly used by beginners to fish breeding, it is capable of efficient and reliable filtration equal to any other filter.The filter functions by drawing water through a layer of gravel. The gravel rests on a slightly raised platform away from the base of the tank. This creates a division between the unfiltered water at the top and a layer of clean water at the bottom, with the gravel acting as a filter. It performs mechanical filtration by trapping large debris, food excess and waste and beneficial bacteria in the gravel layer also perform biological filtration.
Here are 8 reasons why I consider the undergravel filter to be among the best types of filters on sale today.
Reason #1: Temperature Regulation
Water is sucked from the bottom of the fish tank and then pumped back in from the top. This will mix the water up continuosly, as long as you do not turn off the filter. This circulation of water causes every area of the fish tank to experience the same temperatureBecause of this water circulation, every part of the aquarium maintains the same temperature. Ideally, if you keep your fish tank heater closer to the lift tubes, it regulates the water temperature even better.
Reason #2: It Aerates The Water
As the filtered water rises from the bottom through the lift tubes, it will come in contact with outside air. This aerates the water even better than the bubbles in the tank could.
Reason #3: Excellent Mechanical Filtration
The gravel is the filter media in this filtration system and they do an excellent job in trapping debris, food excess and fish waste.
Reason #4: Excellent Biological Filtration
Once the gravel has been given time to age, usually within six weeks without help, it will begin to be colonized by beneficial bacteria. These Organisms reduce organic proteins into nitrate which can simply be discarded each time you change the tank water. The nitrate is also a substance consumed by aquatic plant life.
Reason #5: It Is Capable Of Chemical Filtration
This is one factor ignored by most people, that undergravel filters are capable of being fit with cartridges that perform chemical filtration. Inside these cartridges usually are activated carbon that helps remove heavy metal, complex proteins, odor, color and even chemical treatment.
Reason #6: A Bigger Capacity For Waste
The gravel is the element in the filter that actually does the filtration and because they cover a large area than most filters,, undergravel filters can hold the most waste before it needs to be cleaned.
Reason #7: Simple To Upkeep
Eventually, a layer of muck will build up over the top of the gravel and this layer of muck needs to be cleaned or it will choke the filtration system. How do you clean it? By simplying vacuuming up the muck. One easy way to do this is to use a rubber tube as a siphon when you want to do a water change and simply let it suck up the muck from the top layer of the gravel.
Reason #8: Cheap
Isn't that really the main draw for most of us? The entire undergravel filter set is generally cheap compared to other filtration system. The filter media is the gravel and never needs to be replaced. The parts are quite sturdy but if you need to replace a part, they are cheap.

How can i clean my older fish tank filter?
I am a teacher and the school has older fish filters that i would like to use. but it looks like they weren't properly cleaned when they stopped using them so there is algae and maybe even mold stuck in the filter. How can i get this clean before i put it in my tank?
I already have a new filter going but it is not big enough for my tank. Thank you!
Sorry for the confusion, I meant how can I clean the tubes from the old filter....
If it's a mechanical filter, you will most likely have a sponge or pad that sits inside it. This is the main component of the filter that you will need to clean. Here’s how:
1. Siphon or scoop out some water
You will need about two cups of water from the tank to use to clean the filter’s sponge. For the benefit of your fish, you will want to use existing tank water, not tap water or distilled water. Sure the filter may not smell as clean and fresh, but your fish will be less sensitive to the change. Use your siphon, plastic cup, etc., to remove as much water as you think you’ll need. Drain it into a medium sized bowl, like a small mixing bowl, or drain it in a bucket and transfer it to the bowl.
2. Unplug the filter
This step is pretty self-explanatory. Unplug your mechanical filter to avoid shocking yourself as you clean it. Then take it off of your tank if you can. This will make your life a lot easier. To save your floor, you will want to have an awaiting bowl, bucket or sink.
3. Clean the sponge or pad
Since you’ve already got your bowl of water assembled, this step should be relatively quick and painless, which is good, since you don’t want your fish to be filter-less for long. Simply wash all of the gunk off of the sponge with the water and your hands. If touching aquarium water is too icky for you, either wear gloves or recruit a friend to do it for you.
*If your sponge or pad is horribly dirty, feel free to replace it. But do not do this unless you feel it’s absolutely necessary.
4. Scrub the casing and tubes
Use the leftover water in the bowl to clean the other parts of the filter, or grab a little more from the tank if the water in the bowl is too dirty. You can scrub any hard to reach spots by using a filter cleaning brush, which you can find at most pet supply stores.
5. Put the sponge or pad back
That’s it. Now return the sponge or pad to the filter and return the filter to your fish tank. Pour any remaining water from your cleaning project inside it, if it isn’t crawling with gunk, that is, and turn the filter back on.
