pH between 6.8 and 7.2 (ish)... how much Borax?

Two things:
1) A 52" high wall means 4' of water is only 4" below the wall, so it's not 4.5'--Sorry, Watermom!
2) If your pH is measuring 6.8-7.2, then I suspect you are using strips and they are nearly IMPOSSIBLE to read correctly for pH. You need at least an inexpensive OTO/pH test kit to get a more accurate reading of your pH before you begin adding Borax.

Yep. You're right. Thanks for catching that, Carl!

Thanks everybody. I havent been able to test with the k2006 yet. I did the test with a regular red/yellow kit. I added some ph increase i had from last season to bring it up a bit. Looks like NJ is in for almost a week of rain so Ill check next weekend with the k2006 and report back then.

Remember to maintain chlorine levels DURING the rain days! (Unless you want a nice crop of algae growing, when it stops raining!)
