Any one use the battery powered water pumps to drain/fill their tanks? I want to use one when I move my tank but wanted to get feedback on their usefulness and whether they are safe to use in our reef tanks.
I'm talking about the pumps that operate on 2 D batteries; any experience out there with them?
Thanks
