Are Undergravel filters good for fish tanks?
A UGF is run by an air pump and air stones, or with a powerhead. We feel that these filters can be very effective but are best used in tanks under 55 gallons in size and are NOT appropriate for use in reef tanks. UGFs may work just fine. The trick is to keep the media clean, via a regular maintenance schedule.
Are Undergravel filters obsolete?
The “UGF” is now generally considered obsolete, but they’re cheap and simple enough that they never quite disappear. Whether there’s still a role for undergravel filtration in aquariums is a question with many answers. In aquaponic systems, however, these old standbys offer some surprising advantages.
How much gravel do I need for an undergravel filter?
To ensure maximum efficiency with your filter, you will need to make sure that you have at least 2 to 3 inches of gravel above the filter plate. The gravel should be of mixed grades, but make sure that you don’t have anything so small that can slip under or through the grating.
How effective are undergravel filters?
Undergravel filters are not efficient standalone filters. They do not have the power to filter out debris or chemicals. As a result, they aren’t efficient enough for most large sized tanks. More so, they take a while to start working since the bacteria must build up first.
Can I use regular sponge for aquarium filter?
Regular kitchen sponges are usable as an aquarium filter, as long as it doesn’t have any additives, detergents, or any chemicals that can harm your fishes. These sponges function slower because of the nonporous texture. Only use a regular sponge for water filtration as a last resort.
How do you maintain an undergravel filter?
Because of the small pore size of sponge filters, they are easily clogged by solid waste material. Fortunately, they are just as easily cleaned by removing them from the aquarium and squeezing them in water of approximately the same temperature as that of the aquarium.

Can you have too much gravel in aquarium?
Large gravel can damage stems as you plant them, and the roots hold better to smaller-grade gravel. Sand offers a lot of hold for roots, but deeper areas of sand can develop anaerobic bacteria (bacteria that grows without oxygen), which is thought to deter root growth.
How do you reverse flow undergravel filter?
REVERSE-FLOW UNDERGRAVEL FILTRATION: That is, instead of pulling the water down through the gravel, you push it up through the gravel. You also use a sponge pre-filter on the powerhead, so it is pushing pre-filtered water down the riser tube, out under the plate, and up through the gravel.
