Vacuum it if you can go really slowly. Then brush. If you brush first, it will just make the water more cloudy.
Thanks for the pool math link. Haven't seen that one yet.
The reading was outside the range of the test kit, which measured for ideal ranges. The instructions said to count the drops needed to get into ideal range, which I did. Didn't give me a ph number but their magic book instead gave a recommendation.
Update: as of this morning I am very close to passing the three tests. Water is very clear. Loss of 1.4FC overnight, 0.6CC, but the water is just about crystal clear. I'm going to go ahead and leave the FC high for the one more day and I should be good to go by tomorrow.
Once the FC levels fall back under 10 I will retest Ph. Assuming it's out of whack what's the best stuff to use to raise or lower it? Someone previously mentioned soda ash to raise PH? I see pool math mentions it as well, and muratic acid to lower the Ph? Is this stuff I can get a grocery store, or Walmart?
