Thank you for your help everyone. Sorry I was not back on sooner, but work and other commitments kept me away.

All that I have done the last couple of days is give the pool some vigorous brushing etc and have notice the shade of algae start to lighten which is giving me some hope.

I will get the water tested ASAP (by tomorrow at the latest), but in the meantime since my FC is so low and based on the above post where I should bring it up to around 10, I will go ahead and add some bleach to the pool. Since it is so low (less than 4) I think that around 2 gallons will be safe (should bring the ppm up by about 5.8)

I will also pick up some Borax and add that to the skimmer line and retest every couple of hours until I achieve the correct reading of approx 7.4.

And of course I have the Alkalinity Up already which I will add to help steady those pH swings.
