I just set up a sponge filter in my tank and it's the first time I've used one. Right now, it's floating, and I was just wondering if I need to find something to anchor it or if it's just a matter of waiting until the sponge is fully saturated? Thanks in advance!
It's staying at the bottom now, if a bit unstable. I have the colored marbles (or gems, stones, whatever they're called) instead of gravel, so I'm not sure they would stay on it to hold it down. I'm running out to PetSmart today so I could buy a small thing of gravel for it then.
Well, it has a hard base on it, I guess it's just not enough to keep the sponge down. I should mention I didn't let it float at the top of the tank all night, I taped the tube to the tank so it forced the sponge to the bottom of the tank. And you're welcome, thanks for the info about the gravel.
Sounds like maybe the sponge is full of trapped air. Did you squeeze all the air out of it while holding it under the water surface? I have several of this brand and I never have problems getting them to sit where I put them.
Yes I can attest that some, mine in particular, sink a lot better when you squeeze all the air out first. I belly ached on a thread here about my floating sponge filter, but then once I squeezed it a couple of times and it sank....I had to say to myself, you dummy. LOL
