do you have an airpump in any of your tanks? or a spare one laying around? you really should make a sponge filter for that 5 gal, one boy or two. makes the maintenance so much easier and NEVER have to worry about water quality (they work very very well. especially in small tanks..the amount of media you put into a home made sponge filter is much greater than most commercially available mini filters). if using media from an established tank ive found that they cycle in days, if not instantly. and you dont have to worry about toxins like ammonia..just once a week or so 30% waterchange and substrate clean. and no current for the betta which makes them perfecto in betta tanks.
they are very very easy to make(less than 15 minutes and very few "supplies" needed, which you most likely already have laying about the house anyway, ive given advice and instructions to many members who were interested. i could send you this info if youd like. id highly suggest even just giving it a thought. and if you already use an airpump in one of your tanks, no need for an "extra" plug for anything..you simply use a "T" connector from the existing airline tubing (they are like $1 at the fish store/petsmart).
i use them in all my betta tanks (2.5 gal-6gal) and water quality is never an issue. just a bit more substrate cleaning as they dont remove debris, just deal with the chemical filtration. give it some thought and let me know if you (or anyone else who may be interested) would like some instructions..even if you just "think" about it.
cheers!
I'd love instructions on a DIY sponge filter. Would you mind sending me those?

hi
if you have an established tank, use some media and MAKE your own filter. established media cycles faster so is optimal to use, but new sponges/folss would be fine as well. just test and change your water as appropritae (if you dont know what i mean, just ask...happy to answer) anway, heres how to make one. ive given advice to a few members so ignore any info that doesnt pertain to you 9i copied/pasted). any more questios feel FREE to ask!
here's how to make one. it is reallllly simple.
list of things you will need:
- an old fish food tub or any other container with a lid depending on the size of the tank to house it (like an old peanutbutter jar (plastic of course), big yogurt container, sour cream container, pill jar, etc..make sure they are clean first..no sops just HOT water,).
-something to poke holes in the plastic- a nail and hammer or a drill with a small. sized bit
-gravel or some other material to weight it down
-filter media (sponges work best)
-air pump
-airline tubing
now to build it:
-take the clean container and poke some holes in the bottom (only cover about 25 % with holes)
-poke a hole in the lid of the container that will accommodate the airtube and be just a BIT wider than the tubing(so the air can get out as it bubbles)
-take an amount of gravel and put it in the bottom (a small handful will be enough)
-put the airline tubing thru the hole in the lid and then run it in the container right down into the gravel
-pack the filter material nice and tight around the airline tubing. you can cut sponges to fit. just make sure its packed well. if not, the airbubbles will have lots of "options" to escape. the idea is to get it so that there is good suction thru the media itself, not just the container)as the bubbles rise. if there is lots of airspace in there, the bubbles take the path of least resistance(around the media) and suction will not be as good thru the media as it should be, and the filter will not work as well.
- put the lid on the container that now is weighted with gravel and packed with media.
-turn on the airpump and viola- nearly instant and cheap filter!!!
some troubleshooting advice:
-if it seems to float, add more gravel to weight it down
-test your water daily and do appropriate waterchanges until it cycles.
-if using mature media, ive found that they usually cycle within a week or so (or sometimes instantly if the bio load is low).
- if you dont notice reduction of ammonia within a week or two, try packing with more media...or if it was REALLY jam packed, maybe take a bit out.
these filters require VERY little maintenance. they are NOT mechanical filters (do not remove the solid waste in the tank) so they dont get all gunked up with waste. i have not touched my filter media in months!!!! although this means that with water changes, you will have to syphon out the solid waste- these filters do not do that for you. they just take care of the chemical filtration (turning ammonia into nitrites into nitrates). they do circulate water quite well tho.
good luck and feel FREE to ask if you need any further instruction or clarification. they truly are very very simple to make. once you make one, you might not buy a filter ever again. i know i wont smile.gif its a little extra work to clean the solid waste up, but if you regularly do partial water changes anyway, it is not a big deal as you should be syphoning up the poo anyway.
good luck and have fun making your filter!
cheers
