Hello there. This is the way to go. A little time with the chemistry set is better than scraping algae. Cool to find a group whose sole intention seems to be helping me enjoy a clear, sparkling pool. Thanks everyone.
Gunite and plaster are interchangeable terms. The shell is generally gunite and the smooth surface inside is plaster. That's what your's looks like.Thank all of you for helping me get the pool looking this good. I was living in the dark for over 10 years until I stumbled upon BBB method on the internet. / I really don't know pool construction types: Is this plaster, gunnite or what? Thanks again. I appreciate you. Ron
