Skilter 250 Modification Questions

[newsalt]

I have a Skilter 250 that I modified by using an air pump and wooden airstone. Since this modification, I've seen an increase in the amount of foam that come out of the top but nothing spilling into the collection tray, maybe it's because I only have two fish. Modifing the Skilter this way makes it a co-current skimmer. Does anyone have any ideas on how to modify the skilter to make it counter current. Somehow bringing the water in higher in the tube. I'm intrested in any ideas.

Thanks

if you have a low bioload, then changing from co current to counter current wont increase the skimmate. Skilter modifications are really a waste of time, i spent too much tryin to make that worthless device skim and its just a product of bad engineering.
