I have this piece of driftwood in my new planted tank that is growing some kind of clear slime on it. My new Eheim should be here in a day or two so for right now I'm using a hang on the back filter that is inadequate. I found the driftwood in a local creek. Should I go ahead and take the driftwood out or wait for the Eheim to see if it will clear up? There is very little water circulation with the filter I'm using now. FYI, there was a mixup with the filter... and I should have had it early last week. What do you think?
