Sponge filters are rising in popularity within the aquarium and for good reason. Sponge filters have many benefits, extra biofiltration being one which is always useful in any aquarium setting.
A sponge filter provides a vast area on which bacteria can grow, this means that they help to keep your aquarium water extra clean and healthy once they are established. It has been noted in some studies that sponge is actually one of the best materials to use as bio-media, as it provides so much surface area for bacteria to grow on. They also provide some amount of mechanical filtration which helps to keep your water crystal clear.
Sponge filter power
Sponge filters can be powered by air, this works by using an air pump plugged into the sponge filter. As the air moves up through the filter it creates a small vacuum that pulls water through the sponge, much like how a syphon works.
This means that all those bubbling air stones in your aquarium could be giving you the added benefit of being filters too and still provide some oxygenation to your water.
Because sponge filters are air driven, they are not overly powerful, this makes them ideal for fry tanks. Raising fry is a big part of the hobby for many and filtration is really important to keep the water nice and clean so the fry grow well.
Filtration can often be too powerful for fry as they are easily sucked into power filters which usually means the ends of them.
Sponge filters keep the water healthy for them without causing too much flow for the fry to swim against giving them the best chance of survival.
Sponge filters can be purchased for as little as £5, sometimes less, so the initial outlay is pretty low. They are powered by air which means they are also cheap to run and dont suck up huge amounts of wattage. This is especially true if you are already using air stones in your aquarium, as it wont cost any extra to run that air stone as a filter.
Sponge filters are easily moved. They are only attached to an airline so are easily moved around your aquarium. This also means that if you need to set up another tank (hospital/quarantine tank), you have an easily moved filter that is ready cycled to go straight in with your new or sich fish.
Add a sponge?
If you run an air pump on your aquarium then there is no reason not to add a sponge filter, they come in various sizes and provide far more benefit to your aquarium than an air stone does. Whilst an air stone will oxygenate the water by causing some surface disturbance as the bubbles pop, that is about where its advantages end.
A sponge filter will do that too, but it will also add a vast area to grow some nitrifying bacteria to ensure your aquarium stays nice and healthy. It will also provide some extra mechanical filtration to keep your water crystal clear.
So get those airstones swapped out for some more useful little sponge filters!
