Hi!
Have just moved into a new house which has an above ground round 15ft pool (14 m2). With a little help from a friend who has a pool back in UK have started to get the pool ready: so far I have been basically re-pH ing and chloride shocking for the last 4 weeks, with a green pool still the result! Am I just being too cautious with the chlorine etc??

The pH was ~7.2 yesterday and tonight I have:
Free Cl- ~10ppm
Total ppm: (no colour change when tablet added) (Have a gaurdex kit)

Have been filtering non stop for ages and am on the verge of turning it into a sand pit for the kids!

Tonight I dumped ~700g chlorine shock in as a last resort!

Any advice welcome thanks!
