How often are you adding chlorine? Don't worry about any other numbers right now except chlorine and pH. Do yourself a favor and order a better test kit -- Taylor K-2006. You can click on the Amazon link in my signature to order it. It will make it SO much easier on you. I just checked and they have 16 in stock from Amato Industries which is the place we recommend. You'll be glad you bought it.

The key to killing algae is to sustain the high cl reading. If you let it yo-yo up and down, it will take forever to clear. Run the pump 24/7 and backwash when the pressure rises 8-10psi over clean filter pressure. Did you take a sample to the pool store and ask them to test for metals? Please do so and while you are there, go ahead and let them run a full set of numbers but don't buy a bunch of stuff that they will try and tell you that you need.

Don't test your pH when you have just added chlorine. It will give you a false reading. Hang in there. We'll stick by and continue to help and encourage you! It'll clear if you are consistent with the chlorine levels.

And again, get a good kit. This wouldn't be so hard if you had one.
