Welcome Angie N.
We rely on testing our own pool water with a quality test kit to monitor the water chemistry. We only apply additives when we know exactly what they are and how they affect our water chemistry using the Pool Math calculator. List more information about your pool, equipment, test kit and sanitation plan so we can offer up an action plan.
Above ground 18' x 33' and 52" deep. 20,000 gallons (approx). Sand filter with 2HP pump. New sand this year. Using 4 way test strips along. Had tested at pool store last week and it said balanced. Along with scaling water is not crystal clear. Tried flock with vacuuming to waste and still cloudy.
Test strips are not sufficient and pool store testing will wind up spinning you around in circles while picking your wallet clean. Don't take my word for it, search this forum for those two topics and learn from so many others before you.
You first need a quality test kit we recommend two kits the TF-100 or the Taylor K-2006c. Get a kit, test your water, post your results and take control of your pool with the help of the many great folks who volunteer their time to pay it forward. Most of us have been where you are now and are enjoying Trouble Free Pools now.
What are you using to sanitize your pool now?
Where would be best place to look for suggested testing kits? Amazon? Currently Clorinating granuals or liquid clorine. Have 3" tablets in skimmer and algecide. Got my homework to do to help reduce $$!!
