You know those times where you get into your tank to rearrange or clean something and no matter how hard you try, you end up getting little streaks of salt water down the outside of the glass?? That's not the part I hate. I'm talking about after you clean it and close everything up. You sit back and realize that you should have, or need to do something else in the tank. Then you end up doing the same thing all over again!! It drives me nuts. I know I'm making myself out to be a messy tank keeper but there are times that I have done it 4 times in one night.
