PH levels

Thanks. I scrubbed this am and vacuumed this evening. My FC was 15 not much sun today so will see what it looks like tomorrow. The pressure wasn't very high but I backwashed anyway to be sure. I did notice the ladder in the deep end that I brushed yesterday had a lot of yellowish green on it again this afternoon so not really sure I've even killed the algae yet? Not sure how it's possible with the FC level as high as it's been the last 3 days.

It could be the ladder was were the algae started and is still clinging on for dear life. Maybe you could take it out and clean it real good. Leave it out until the pool clears. That way you're taking it away from the whole equation.

Also, search the forum about adding a small amount of DE to your sand filter to give it an extra cleaning boost.

Good news is the pool is clear and looks good no dark spots. Bad news I still notice settlement. I vacuumed and back washed yesterday. I checked again today by brushing and it's less but still have the settlement. Do I still have a algae problem?

See how much chlorine you lose this evening from sundown to within one hour of sunrise. If you lose more than 1ppm, you are still fighting something in the water.

Ok. It was 6.8 FC and 0 cc tonight. Will see what happens tomorrow in the am.
