Pool Suggest/Lessons for a New Pool
Great looking pool-wish mine was that big. Love the expanded sitting area idea. Looks like you lucked out on the dig-my builders (Anthony Sylvan) hit sold granite which we had to chip out for an extra cost. This is my second season (near Philadelphia), so feel free to ask questions regarding lessons since I live in the same area as you. (send me a private message and I will give you my email).
Of note-my plaster is also white and I also have a Nature 2 system, DE filter. I found, that entering into the 2nd season, the Nature 2 was causing the plaster to develop a slight yellow-orange tinted spotty color in various pool areas (like a film, that will not come off)(makes the pool bottom look dirty-wish I had used a color blue tinted plaster). I also had an algae breakout (no visible green-but lost all of the chlorine over one night and the pool got cloudy). After much help from the forums (this one and pool forum), we all agreed the algae was due to the low chlorine inventory of the NAture 2 system and its inability to handle a sudden outbreak (came from a week of rain)(I was using the BBB method and maintaining 1ppm chlorine (even higher than NAture 2 recommends with a 30-40 CYA). Lessons learned is a that I increased my chlorine level up to 2.5-3.5ppm and quit using the Nature 2 system!!! (saves me $100 cartridge each season). You should do some searches, before you buy a replacement cartridge.
I also invested in a sold winter pool cover (not mesh). When I opened the pool this past May the water was clear!!! this year, where as my neighbor's was pea green (he has a mesh). You need poly 60 and shock levels of chlorine before covering that pool
I also late this season bought a salt water generator (Autopilot Digital) as I got tired of lugging all of those chlorox bottles. I was using 1.5ppm chlorine per day in July-August(my pool is in the southside no trees of the house (which for me was a 1.4gal jug of chlorox every 2 days-you will be more since your pool looks like a 45000 gal pool. The Autopilot SWG has been tremendous in the past 3 weeks-wonder how I managed without it, and I even installed it myself and saved $1000. There is a local installer but he charges you retail prices and the install is very easy-
A must is a good pool tester so you test daily-I found the pool stores are all over the map as to results (including Leslie). They sell a good titrant kit here on this forum. I myself shifted over to LaMotte ColorQ. They also have a PC-4. Both use a device that measures the color intensity of some reagent drops you put into a test tube and measure more consistently the various pool chemistry values. I have been very happy with ColorQ and have found the results to have reasonable accuracy when I compare results with my titrant kit.
It sounds like your landscaping is figured out. Make sure you have at least a 5ft buffer zone between your grass and the pool OR lawn mowing will be guaranteed to migrate to the water. I have 4ft with a fence and rock, and still pick up some grass clippings from the pool after I mow and of course they all sink so have to run the Polaris 360 longer.
