What are the factors in the number sentence 4x28?
4 and 28 are factors of 112.
If you double 2 x 24 then 4x28 then 8x2 16 and so on for 6000 times what figure do you get?
2^6000 = 1.513470582 E+1806
Why would a 12 foot by 3 foot vinyl pool you shocked three times and got the free chlorine level to 5 and the pH to 75 now have green cloudy water if there was 0 alkaline in the water used to fill it?
Try adding some algaecide. It sounds like you have an algae problem. How often are you shocking your pool. If it's extremely sunny, then your free chlorine will be reduced quickly. I have had good luck with adding 5 gals of liquid chlorine to clear up algae and then follow up with algaecide. ou could use less, as my pool is 4x28. Don't forget to run your filter a couple of hours a day to turn over the water. Good Luck. New answer: Disregard the above answer for the following reasons.Your fill water may be from a well or other source even though it is "city" water. Cities mix their water sources. This sometimes results in either somewhat milky cloudy ( which is sometimes called "air entrained" ) or it comes in a cloudy green. Further, 2 hrs. per day is not sufficient to maintain water clarity. In most pools in the example above and larger require from 6 to 12 hrs daily and more with the combined efforts of adding the correct amounts of chemicals and sanitizer. By now your pool has most certainly cleared. Filter that green water non stop until the water becomes fairly clear then you can cut back the filter time to whatever time is required to maintain "your" own pool. Different pools with different equipment configurations require different run times. Even the pool next door will sometimes require a different regimen of maintenance. After filtration of at least 6 hrs. you can then start adding chlorine and adjusting pH.Ken
