Good news/bad news so far with the latest updates. The good is the builder is working with you, really trying to get things setup, and is doing what PBs can do best, trying to get you to swim. Even the best PBs have the best intentions with water chemistry, but few are experts at it. They do their thing, we do our thing over here at TFP.
The bad news is you have a purple pool! Don't think I've ever seen a purple pool. Kinda cool looking, but probably not a TFP chemistry balance in there. Draining some of the water out will be helpful in clearing some of whatever is in there out, as well as get the water to the proper height. But more good news, whatever the chemistry is, you can fix it with the TFP methods. All that magic stuff they piled up for you can likely go in the trash, and you arm yourself with some chlorine, muriatic acid, maybe some Borax or washing soda and bam, your at perfect chemistry.
Speaking of water levels, when are they getting the auto cover installed and hooked up? That doesn't help you now with the water levels, but will for sure in the future.
Really like the labels, when they finished construction on my pool at the end of last year and closed it, they labeled everything. Not the arrows, but at least what each valve does and was nice.
