That's awesome! Now that I think about it, bobbi pins usually have paint on them or some sort of cover that does chip away after awhile. I'm not sure if the paint/covering is toxic, but I'd be careful with it.
I left it in there last night and all it seemed to do was make the fish more active and happy. If i see some kind of harm going i will remove it and learn from my mistake. :) your awesome. lol thanks again
Hey I got an idea. My whisper filter does produce too much of a current. So i put a bobi pen where the water pours out from the filter. It stopped a lot of the current. Do you think this is safe? I didn't know if it would harm the fish or what.
Thanks and sorry to bother you.
