Was given an intext 15x42 pool w/o instructions. Filled it, and have tried to treat it, but water is cloudy. Pump runs 24 hours, new filter every 2 weeks.

I have no idea what the heck I'm doing, I honestly thought I could "fill it and forget it". NOT SO MUCH!

So many questions..do they make a pool for dummies book?

1) how many gallons does this hold
2) to measure out chemicals - do I used a baking measuring cup?
3) what is ph, ppm fre chlorine, ppm total alkalinity, ppm stabilizer? if my levels are low, do I have to purchase separate chemicals to bring them up, or is there one that will do the job
4) does the filter need to run steady or can it be shut off
5) pool is vacuumed daily
