Hi Mind;

1. Do not worry about alkalinity or calcium. Do not ADD anything to raise them.
2. If you have an OTO/phenol red kit, good. If not, get one (drops that turn yellow if chlorine is present)
3. Tell us how many gallons are in your pool -- or which Intex model it is -- or what diameter and wall height it is.
4. Tell us what chemicals you've been using since you last filled the pool.
5. Tell us what your strips say the CYA (stabilizer) level is.
6. Add 1/4 gallon of bleach per 5,000 gallons of pool water each EVENING; skip if OTO results are dark yellow the following evening.
