Thanks -
first - the 6.2 ph reading came from my local pool store. I have both the strips and the tester that you add yellow and red drops. I just took the strip reading, showing ultra low ph. The drop tester turns water yellowish when I add the red drops indicating a very lowph. I will work first on getting the PH up.

second - I did the bleach
third - I am running the filter 24/7 and will add borax (1/2 box ? what size box?)
forth - I'm sure the copper came from the Algicide I added since this is when the water started to change color to greenish/yellow upon adding shock. Like I said, the water quickly turns back to clear. I do have a heater. The copper reading of 1.7 also came from my local store.

fifth - I did the fingernail test on the black spots and it does dissipate.

So, tomorrow I will work on getting the ph up using the borax, correct? Don't add the backing soda yet, correct? What about the alkalinity, don't worry yet? Is there a reason you don't want me to raise both ph and alkalinity at same time using baking soda? Lastly, what do I do about copper? Thanks a million, again. Did I forget anything?
