I've been mostly watching and not posting much lately.
You quickly pick up ways to improve your all glass tank building techniques from the experiences with the first few attempts. They start to become very easy to build after that.
The mistake with the inside seal masking tape is something you may not realize at first that must be removed as soon as you finish smearing the bead.
Plan ahead next time and make a few angled cuts through the tape with a razor blade.
This will make it easier to lift a tab that you can grab to help peel off the masking tape.
The tape with the still sticky sealant on it will curl and brush the sides making it necessary to do more clean up after the sealant has cured. By cutting the tape into halves or thirds the lengths you remove will be of a more manageable lengths. It will help keep the final clean up easier.
