Evie, You deserve some thanks too. You being determined, determined about fish aquariums got me realizing a solution was needed in the first place. Lol.
EuphorialQueen, by all means post the link all you wish. This is all about sharing techniques for all of us builders. Thank you for your comments. :)
Jisgr8, you get a lot of credit too. Without you letting us know about building a wall inside of pools, I never would have thought along the lines in the second method. Knowing what you told us, let me think about other possibilities beyond how we used to do it.
