The turkey baster or powerhead method works well but it can take a while. It is probably the safest method.
I didn't know you could blow on them!! Ugh! It was so hard to get off of the bucket and then off of the tub! I am sure I irritated the crap out of it trying to remove it from the side when moving it. Now I know! I haven't messed with t since I put it in the display and I'm not in a huge hurry to move it but I was thinking king I'd like to rearrange I think. I'm not in love with the layout and it might also help when adding my fish from quarantine. Anyway. Thanks for the info!
