1. Test pH Levels
Use HTH Multi-Purpose 6-Way Test Strips to test the pH level. The ideal pH range is between 7.2 and 7.8. If the pH is too low, raise it with HTH® pH Increaser.
2. Determine Dosage
Looking at the instruction labels on the back of the pack, determine necessary quantity depending on pool volume (gallons) and pH level from step 1.
3. Apply Directly to Water or Skimmer
With the pump running, add to pool skimmer or directly to the pool water spread evenly around the deep end of the pool. Use a pool brush to disperse any undissolved chemicals.
