Hello. I'm a newbie at this so please keep in mind when responding. I have a decent understanding of what I need to do and chemistry of my pool however, I'm a bit confused with the proper target levels. For instance, the pool math app recommends target alkalinity of 50-90 where Leslie's has it at 80-120 for the same configuration of my pool. Also calcium hardness is recommended at 250-650 on the app vs. 200-400 with Leslie's. There are a few other subtle differences.
Finally, I can't find a reference to phosphate on the app but I'm testing at 333, is that a concern?
Thanks.
