The pool isn;t clear because I didn't give explicit instructions about water treatment, just convincing you that you need your opwn test kit and that the pool store is not your friend.Now that we have some decent results, we can get down to it. You need to perform the
Shock Level And Maintain process.
For 70 CYA, that means bringing the FC level up to 28 and replenishing it to keep it at 28 again and again every few hours until it passes all three tests. And thereafter, never letting it dip below 5. The alternative is to replace about a third of your water now, which will lower CYA level to 45 or so, which will lower shock level to 18 and afterwards, a minimum of 4. The payoff is that you may never have to do this again, and your water will be crystalline and sparkling well before Fourth of July.
To get from 7 to 28 is going to take a little over 3 full jugs of 8.25% Clorox (or the equivalent in stronger liquid pool chlorine) and probably two or three times that much the remainder of the day and that much again the next day and probably more, but at a lower rate. If all you have is some green tint and a little sliminess, it could be over by the end of the weekend. A seriously green and chunky pool usually takes about two weeks, but you're not that far gone.
So... it's your choice. Start a partial drain now and delay the SLAM process a little but save a bit of bleach, or get started tonight. You won't lose any of the bleach to sunlight overnight, so you could get a good kill going and hammer it again really early in the morning and get another big kill over before the sun really starts hitting the water. But long term, you'll be happier with a lower CYA level.
