DIY Sponge Filter

[IovaykInD]

Could I use a powerhead to power a sponge filter? Won't that make it a lot stronger? And also, does it make it fry unsafe, or would the fry still not get sucked in? I could use the slowest rate for the powerhead, so I'm wondering if fry can still get sucked into the filter.

yes it will !

here are some interesting links:

hope it helps

btw, I don't think there would be a problem with the fry, just test it out first... good luck

As long as your open cell foam has small enough cells, it is not likely that fry will get sucked in. When I use powerheads on sponge filter it is usually because I want to run several in the same tank to give greater area, in which case the flow through each is not that much greater.

Remember, most fry do not like strong currents, so adding a powerful powerhead to a fry tank may not be the best idea - a lot depends on the fish and the size of the tank.

Is there any way the you could slow down the output of a powerhead? Maybe divert into a wall or something? Would putting foam over the output help at all?

What about Hamburger Matten Filter (HMF)?

It's a sponge filter but most of all, it's a biological filter!

The foam is already a biological filter. All sponge filters are for mechanical and biological filtration, just no chemical filtration unless you modify it. I created one and it is working great, however in the future, I want to use it for a 20 gallon long fry tank. I think the output would be too great for the fry to handle, and it's already set at the lowest rate. What could I do to slow it down? Is there any way that I can divert the output and slow down the current? It is an Aquaclear Powerhead 301.

Thanks a bunch!!! The information was really helpful.

not sure how, but you could put a small piece of foam in the output and hold it in with something non-permanent like a mesh or pantihose
