First time pool owner via a new home purchase. Studying about SWCG. Should I use or not. I really like the idea of testing and managing my pool as a hobby. With that said here are the options I am looking at.

1. Use pool testing and chemicals via pinch a penny (what I am doing now)
2. Employ the BBB method using store bought products (to save money....also am awaiting delivery of my Taylor K-2006 kit)
3. Hire a monthly pool service which installs a SWCG (Maintainence of the SWCG and other chems included in the monthly price)
4. Purchasing a SWCG system from Amazon and installing myself and use the BBB method to adjust as necessary.

Looking for the most cost effective and practical solution.

As stated I am a newbie to this and would appreciate your feedback.

I am a do it your self person but also value my time and understand some things are worth paying for and not wasting your valuable time keeping up with.

For reference I have a marcite unground pool (approx 20,000 gallons). The marcite is wearing and will likely need to be replaced in one to two years.
