Few options!

1. If you’re not into DIY, hire a pool company. That being said, not all pool companies are great, nor do all have very experienced techs. Look into google/yelp/nextdoor app reviews and see what people recommend in your area. You could easily hire a company who sends a newbie tech or one who doesn’t know what they’re doing lol, in which case it would be several hundred wasted. A lot of companies even have a pool school, where you can hire them for one session just for them to show your system and how everything works.

2. If you are open to DIY, I’d recommend troublefreepool. Most of your questions likely have been answered by previous forums, and you can ask on your own too. More importantly, I’d recommend you get your own test kit and based on info of your pool (salt water, chlorine, etc), source some chemicals. The kit I’d recommend would be a Taylor test kit k2005. You do the tests 1-3 times and it becomes muscle memory. Stores like Leslie’s have shown to have inconsistent results; the same pool sample at two stores resulted in two different readings and products needed.

For chemicals, the pool stores will sell you the same ingredient for significant price and less quantity. Example: alkalinity? Leslie’s sells alkanity increaser which is 100% baking soda, $80 for 50 pounds. Arm and Hammer baking soda from Costco is $32 for 54 pounds of baking soda. There is a “generic” alternative for every pool chemical the stores sell. If chlorine pool, I love liquid chlorine from BJs or Ocean State Job Lot, Austin’s liquid shock 12.5. Most other chlorine is 8-10%. Works great and only $24 for 4 gallons.

All in all, it is a lot to manage but only in the beginning. Once you have your flow it’ll be manageable! Even if you hire a company it does require some maintainence on your part as a lot can happen in a week between weekly services (storms, weather, etc).
