sponge filter efficiency vs protien skimmer

[ctenophors rule]

ok

i have had this on the diy area for long enough to recieve 100 views and no responses.

their is a link here...i would realy like some input....even if someone told me that they didn't know, at least that would make it easier to accept that the answer isn't staring me right in the face and i just can't see it...

thanks all

I think a lot of people are having trouble visualizing what your talking about

IMO, sponge filters on the intake side of a protein skimmer (essentially what your doing) are trouble. As they clog, the flow reduces and reduces the efficiency of the skimmer. Best to keep sponge filters and skimmers as two separate items.

thanks bill i attatched a diagram....though i cant figure out how to make it bigger, and i think i cleared up some of the confusion.

I took a look, more or less along the lines of what I thought you might be trying.

I use alot of sponge filters in my guppy tanks. They work best with big bubbles that move more water. I have all my DIY sponge filters runing off of full open standard airline. The smallest bubble I'd use in one is like through a coarse airstone. And even then the bubbles are to big to efficiently run a counter current skimmer.

are you saying that smaller bubbles will move less water? do the smaller bubbles just require more presure which equals less air or do they jut displace less, even though their is the same amount of air?

 

[tabwyo]

It's more a displacement thing. The larger bubles push more water ahead of them as they rise than smaller bubbles. Thus creating a current. The larger the bubble the faster it will rise and the more water it'll move with it. I know this is an extremely generalized and simplified statement. But for hobby purposes it works.

All I can say is "Say What!"

I am at a total loss as to what I am looking at in that picture and have built numerous skimmers.
I must be getting senile. :worried:
