Can I use black plastic electrical tape?

Finally got around to applying some tape. To me it looks MUCH better as I totally hate a gap of air between the top of the water and the top frame. Personally I think that I did a pretty good job of laying the tape straight and even. The marble look in the first image isn't really there, just light reflection. Same with the orange lines at the upper part of the second image.

I think it looks a LOT better with the tape. Any opinions?

Looks good. I did the same thing once
