No problem. We can help you, but you'll have a small learning curve yourself. So let's start with the following:
- Your test kit is only designed to tell you if you have "some" chlorine (Total Chlorine - no free or combined). It won't measure precise amounts of chlorine high enough when you need it. For that and all the other important tests you'll need a better kit to use at home. It's a one-time cost that will last all season and part of next. It will save you money from the pool store because you'll know exactly what you need without waste. We recommended the TF-100 (link below) or Taylor K-2006C. That should be your #1 priority.
- Have you ever added any stabilizer/conditioner? This will tell us the "CYA" level which in-turn drives your proper Free Chlorine (FC) level.
- Until you get the test kit, you need to keep some Free Chlorine (FC) in the water to prevent algae. We do this with regular bleach which is the same as chlorine. If you haven't added any chlorine yet, you should add about 1/4 gallon of bleach each evening.
- Your pH needs to be in the mid-7s. You can increase pH by using borax from the grocery store.
- Lastly, you're going to have to bookmark and refer to those links below in my sig. The Chemicals list tells you what to use in your water, the Levels list tells you what each one should be, and the Poolmath Calculator helps you to know how much to add.
But all of this starts with proper testing. For now, increase the pH to the Mid-7s, increase FC (your tester only says "CL") to about 4, and order one of the recommended test kits. I highly recommend the TF-100 (with speed stir). It will save you money in the long-run. While some of this info may seem very foreign and overwhelming at first, with some review and repetition you will have the knowledge to be 100% in control of your water. You will save money, have clean water, and be in control which is what TFP is all about.
So start with those tips and keep in touch if you have questions and once you get the proper test kit in your hands so you can post a full set of test numbers for us. Have a nice evening.
