These filters are an excellent filter for tanks with shrimp or small fish like Endlers or guppies.

The Sponge filter is the most simple to use and understand. It’s most common use is for small sensitive fish like the Betta, newborn fry after breeding and

I just upgraded from a 20 Gallon tank to a 55 gallon long tank. I have a 350 L/h hanging filter in the tank. I love the sound of the waterfall noise the filter makes. But I have goldfish and know they need the better filtration. Would it hurt to add an additional sponge filter into the tank? The fish did great in the smaller tank the year they were in it, and I’m worried my current filter wont be enough. My tank has been modified to also be a coffee table (low on space) so I’m not too enthusiastic about a external canister filter. This is also an ideal filter for small tank with Betta or other small fish. The filter is loved by its powerful features such as s

Meet Sparky, a micro filter for fish tanks that only costs $3. It is so simple to make and it is the perfect size for a betta tank or another small aquarium. If you want to use it with a larger tank, you can just double up!Because of their small size and frequent lack of filtration, smallfish tanks and fish bowls require a great deal more maintenance than alarger fish tank that has a reasonable probability of becoming - andremaining - stable.If your fish tank is either under ten gallons in totalcapacity or is not filtered, it is a small tank or bowl andshould only be considered by experienced aquarium keepers whounderstand the drawbacks and disadvantages of such an environment forpet fish, and are willing to take on the extra challenge and additionalmaintenance required for these small aquariums.Also, the more frequent the water changes are, the less importantit is that the water changes be small. By keeping the frequency ofthese water changes high - at least twice a week for a small fishtank with a filter and at least every other day for a fish bowlwithout a filter - the stress of the water changes issignificantly mitigated.Fish bowls are slightly different from small fish tanks. Primarily,since a fish bowl does not have filtration (see the definitionsabove), a fish bowl is only a septic tank collecting thefish's waste and making the fish soak in it.Introducing a cheap (around $4) small tank filter called "Discard-A-Filter" (I'd say one of these is good for an aquarium of up to 2 gallons. Use two and you could probably go up to 5 gallons. Note that you need an air pump to operate it, but these can also be quite cheap and you only need one, even to run two of these filters.) The filter is so cheap because the manufacturer expects you to just toss it in the trash every month and buy a new one (which would actually end up costing you quite a bit over the life of your fish). However, and this is not because I'm so eco-conscious (I'm reasonable: I don't go overboard, but do try to limit unneccessary waste when I can), the idea of just chucking a relatively large, sturdily manufactured object just rubs me the wrong way. It doesn't help that I happen to know that the only thing about the filter that stops working is the activated charcoal (and a smaller quantity of zeolite, which you can also, optionally, add), which absorbs harmful chemicals from the water -- it's absorbed everything it could, and has to be replaced with a fresh batch, there's no getting around this one. So, in this instructable I'll show you what you need to do to keep happily and cheaply reusing this filter, as well as improving its function.
