My local Petco sells some nicely shaped "driftwood" that they simply call "Aquatic Wood". They have a whole tank full of them and it's a dark brown color. The water they are in is crystal clear so I don't think they are leaching any tannins.
Does anyone have experience with wood from Petco? Thanks
I bought some of this so-called driftwood...it's not bad. I had to wash off all the existing algae as best I could, but other than that it hasn't given me any problems. My ghost shrimp loved it! They started eating everything on it.
