RE: In-Ground, DE Filter Pool With Clear Green Water

[barbjack]

Still waitning on the test kit. We closed the pool after my last post at 1.0 chlorine. Opened it today, 4 days later. The water is much clearer and a much lighter shade of green. The algae/whatever that was coating the walls is a lot less too, although back in a few spots. I tested today with the two-way test I have and Chlorine is back down to between 1.0 and 0.6, pH is steady at 7.8 (if the tests are accurate).

We added one more gallon of 10% chlorine, and brushed. Filter pressure was up again also, so we'll backwash too. I will be doing the second dose of polyquat this afternoon after the chlorine, brushing and backwashing. Then I'll test the chlorine again. We have one more bottle, if it drops this afternoon, I'll add the second bottle, if it doesn't, I'll test in the morning and add it then, if it needs it.(which it probably will).

I will do the CYA test as soon as the new test kit arrives (hurry, hurry mail!) I'm really
curious as to it's level too, since we've used nothing but the pucks for the last 3 years.
Before that the pool guy used them too, but I don't know if he supplimented with liquid chlorine or did any shock treatments.

But as I said, it looks so much better, I can see light at the end of the green tunnel now! lol.

Again, thanks for all the help!
