Hi - like everyone else trying to keep kids entertained during the pandemic, we bought a 12' round Intex pool. I feel like I'm constantly having to add more chlorine. I have a floater with 3 mini tabs and I feel like I'm adding "shock" level chlorine every few days. Is this normal? I use test strips and typically the TC and FC are close to balanced but the FC always drops first. Is this normal? It is ~1700 gallons and the water is nice and clear and gets at least 5 days of use per week by my kiddos. It gets full sun from 10 am to 5 pm and runs around 90 degrees. The pH is always on the high side because we have very hard water where I live (12 year water heaters last 5-6 years). We run our pump 24/7 mostly because I would probably forget to turn it off and on. Thanks!
