New California resident and pool owner here. Newly relocated from Virginia to California and now am the proud owner of a small, but very nice, in-ground pool and spa combo. Rough calculations put it about 12-15,000 gallons. Built about 1998 with all original Sta-Rite equipment, still chugging along. Hoping to relieve my pool service guy soon, and improve my water chemistry and bank account. Looking forward to learning a lot from the knowledge base here. Just ordered my TF-Pro test kit to get me going. Previously owned a hot tub for the past 7 years and performed all my own maintenance, so not a complete Noob to water chemistry.
