I am in the label printing business and I have a salt water aquarium. I cam up with these labels and use them on my own tank so I thought others may love them also. The cable marking labels are self explanatory. The tank maintenance label is a unique material. It can be taken off and put back on again and leaves little or no residue on the surface. I keep mine on the side of my stand, take it off each month and write my new information on when I do water changes, then slap it back on the stand. We have just started selling these on Amazon. The link is. Or go to Amazon.com and type in aquarium labels.
