I have been looking for the past couple of days for directions to make a sponge filter and have yet to find any clear directions. If anyone has any instructions or links to clear instructions I'd appreciate it.

The instructions I've seen have all been to the effect of find sponge, cut to size, cut hole in the center and insert pvc pipe then insert air line into pvc pipe and place in tank (after leaving the sponge in the filter on another tank for a while). Needless to say these didnt really help me any. So if anyone has any clearer directions I'd appreciate them.

Thanks,

what you can do is cut a PVC pipe and drill holes in a circular pattern at the area where you are attaching the sponge. then attach the PVC pipe to the intake area of a powerhead. that makes for a nice sponge filter.
 
One more question, where is the best place to find sponge? I looked at both wal-mart and the local petco and couldnt find any large sponge filters to use for one.
 
Some sponge material has extra chemicals added as fire retardent or anti-mold. They don't always say, so you may be taking a chance by using just any old foam. Fabric stores stock foam as well, so you might check one of those.

For fry, an air-driven filter is just fine. Get some 1" tubing like they use for undergravels. You can drill a hole through the foam by putting some nicks in the end of the tubing and turning it into the foam. When you've drilled it deep enough, just tear off the foam in the center and you have a hole.

Cut some slots in the end of the tubing and push it into the foam. Put some aquarium-safe pebbles in the bottom of the hole, and get an airstone down there.
 
It is for a fry tank, I'm just wondering how well an air pump driven sponge filter actually works. Does it fully circulate the water? or would I have to have a couple of sponge filters to filter the whole tank? Just trying to figure out what all I need to buy to make one work for a fry tank... :read:

Thanks again,

personally I would just look for a cheapie on line sponge filter..I made one and after all that time and trouble found spnge filters for as little as$5 and they are set up to either stick to the wall of an aquarium or sink to the bottom.

they are very good bio fliters and work well for a fry tank..
 
The only problem with ordering a filter is that I had fry born over the weekend, bought guppies last week so thought I had more time to prepare before their first fry were born.

Thanks again,

i raised my guppy fry by very frequent water changes. i had a total of 13 i believe, but lost most of them due to ravenous snails. (witnessed the death of most of the fry by common pond snails; fell from the top of the water onto the sleeping fry) some of them needed to be culled anyway. i eventually had three to survive but then i had gone away to miami for the summer and my mom overfed my corys with shrimp pellets, basically most of my fish died from that. my corys, ADFs, two tetras, two zebra danios surived. those fry died though.
