Is there a specific reason to make your own? Because if you're trying to save money, I'd just buy some sponge filters, they generally around 5 dollars each, or if you buy from china you can get them for 2 each shipped.

 

I want to make my own mostly to say I did. But also to avoid the problem of baby shrimp getting sucked up in a over the top filter.

Where would I get the $5 foam at though? Do you know of a store? I can't find one, that's why I ask.

 

Go to the dollar store and get some sponges that you wash your car with! They work great! good luck.

 

go to e_bay and search for "sponge filter replacement sponge"

 

You might try looking at foam prefilters. Search for that and you'll find many online. There are pre-made shapes to fit over various filter intakes, but it sounds like you'd prefer a block to cut up yourself. I did too, and bought this:

It's open cell, and a larger pore size than any foam/sponge I can think of from the hardware/craft/dollar store; which improves flow and reduces cleaning requirements. Provides good biological filtration. I like it.

 

Purchase an AquaClear filter sponge replacement.
I use the generic ones from Big Al's, to replace or create sponges media for all my filters.

 

Not seeing the ones for $2 each shipped.

 

i have been using the car washing sponges for years. Cheap and effective. Look at the Dollar store,

 

I'm using the fluval edge prefilter sponge on powerheads for a 10g and a 3g tank and it works very well. I don't know that I would do this for an unplanted 10g but in a planted tank it appears to be more than sufficient. $2.50 each and they fit over the inlet for most any small filter or powerhead...

 

Just saw this in another thread, it looks like what you're after, though the price is rather higher than a dollar store car sponge.

Poret foam

 

Yeah the Poret Foam looks like it would work great, he just charges so so much. I am willing to spend some money, but not that much. Thanks though.

 

How about $2.79 per double sponge filter?
I did a search for "sponge filter" on eBay, clicked on Buy it now, and found the first listing to be double sponge filters for $1.00 each. Shipping is $1.79.
They ship from Hong Kong and should be here in a week or two.

 

Most excellent. Thank you.

Before some buys a ton of them and gets a surprise, the $1.xx shipping is PER item, not as a whole lot. Still under $3 each.
