I just purchased the Marineland/Tetra half-moon 10 gallon aquarium kit yesterday and attempted to set it up last night. Unfortunately the product packaging/signage was taped to the inside of the glass in six places with degrading cellophane tape. The tape film was removed, but in many tiny pieces and I was left with the sticky adhesive residue. I attempted using a straight razor blade to remove the adhesive, but it just seemed to spread it along (as it was also challenging to scrape the curved glass of the half-moon design). Is there a solvent like goo-be-gone that once used can be safely completely removed from the tank so as not to harm my water and fish?
