Hello, I wasn’t around for the pool build and wife doesn’t remember. Can anyone tell us what layer is the original vs wear and tear. Looks like a stained layer, non-stained, light blue and sky blue.
Great, this answers my question. I have a 15k pool and my Intellichlor 40 looks to be going out and was wondering why I had a 40 vs the 20 installed. I am thinking of replacing with an Ichlor 30, that should work, right? It's 2x the size of the pool.
