Aqualeisure dolfino 6 foot 424 gallon easy set up pool with pump

Hello we just set up our pool last night.

We added algae chlorinating liquid. Pool is crystal clear. Bought tester dip stick. Seems everything is off.

Any suggestions on best way to ensure safe swimming?

A 600 gallon pool is more like a spa, than a pool. The reason is the small number of gallons compared to the (relatively) large number of people.

But, with only 600 gallons you need to plan on draining and refilling maybe once every 2 weeks, or perhaps, after very 10 - 12 uses.
