Sponge filter

[caterpillar5]

If i have a sponge filter connected up to an airpump is it necessary for an airstone? does the airstone just create bubbles?

With a filter you dont need an air pump,(air pump running a filter counts as a filter) there just used for decoration, or people think that there fish needs air bubbles, If there air bubbles hit the surface and cause big bubbles then that can effect plants by releasing the carbon dioxide they need.

Not that you needed to know that lol.

I could have mis-understood the original question, but did caterpillar5 ask if airstone is needed in the sponge filter? At least that is what I do to all sponge filters....

If that wasn't what caterpillar5 asked, sorry, ignore this message...

that was my question... i was asking if a sponge filter needed an airstone or not? ive heard all u can do is just attached the air tubing straight to the sponge filter with no airstone.

No you dont need an airstone within the sponge filter. The bubbles create the suction to pull water thro the sponge.

I could be wrong, but I read a while back that it helps to have air stone in the sponge filter. Am I making a wrong assumption?

Logic says that bigger the bubbles, more the suction. Please also see this link for DIY sponge filter construction and he mentions that he does not use airstones.

Aha I remember where I read it...

It was in fact written on the instruction of the sponge filter that I have received from a guy who sells many of them in AquaBid.com... He was highly recomending it and I didn't question it...

Basically this filter consists of a square block of sponge glued to a white tile, a hole in the middle, a while PVC tube with slits cut at the bottom, a hole at the top of the tube for ait tubes to go in and he was recomending to put an air stone in the tube which should be at the near bottom of the sponge.

So should I remove it? I will, if that makes it more efficient!

I use a air stone in the middle to pull water through the spunge, otherwise it wont work, i have 2 homemade ones in my discus tank

I guess you drilled a small hole and squized in an airstone/tube into the sponge?
