What sponge media do you guys use to baffle your filter outflow? I have two 10gal divided tanks with Aqueon 10 filters. Of course the outflow is insane. I tried an Aquaclear Filter sponge (the sponge from the three-level filtration system), but the water flowed like it didn't even exist. I didn't want to chance using a kitchen sponge of any sort, due to chemicals. I saw the sponges that are used for Sponge Filters ie. fluval edge, but I didn't know if they would allow too much flow, like the Aquaclear sponge. I'm frustrated with my current baffle situation. I tried the bottle baffle and my bettas are way too curious. I can't chance them getting stuck. So I bought some poly fill, cut it, folded it, and stuck it up the outflow, allowing it to hang out and submerge slightly in the tank water. It's worked for a while but they fall out. If I have any evaporation in the tank at all, the water flow pushes it out and straight to the bottom of the tank. I was scared to death that my male DT was stuck under it! Instead I found him floating around in the tank like a balloon. This morning my other tank's baffle fell out and my female VT was hiding in the corner. I was SOOOO mad!! I really want to use a sponge, but not sure what type to purchase. Thanks!
Oh, one more question re: filter baffling . . . Originally I had put a little poly fill in my intake tube as well. What I discovered is that it completed arrested the water flow in my filter. The outflow was a mere dribble, if even that. I can't imagine what it may have been doing in overworking the motor. Would sponge do the same thing, since it's so dense? I've read about using panty hose? Did I just use too much poly fill? Thanks again!
