Switched from sand to Zoe clear pool worst ever in 10 years! Can some one help? I was not given instructions so I did not add gravel at first now I have gravel I did not back wash 3 times so pool is very cloudy should I just dump and go back to sand? Tried to flock but pool was so cloudy not sure if I vacuumed to waste enough when I put samples in 5 gallon buckets I see telly swill at bottom after letting it sit for 8 to 12 hours
