Hopefully someone can help.
Pool greenish/ a little cloudy, with pH on high side (7.8). Ground with fine sediment which is difficult to appreciate until brushing (easily brushed off). Initially thought this was dirt, but continued to re-accumulate despite daily vacuuming (sometimes 2 runs with my Polaris robot, as well as manual vacuuming). No classic algae appreciated on floor/ walls. All started a couple weeks ago after rain.
Yesterday morning I treated with dry acid (pH around 7.8/7.9) after changing filters, then a few hours later shocked (3 and a half gallons liquid shock, 12.5%). Filter has been on since then, now 28 hours later. Have vacuumed with my Polaris x 2 and brushed a few times. Still green/ cloudy (looks same).
Chemistries below.
Suggestions?
Thx
30,000 Gallon Vinyl Chlorine Pool with filter cartridges (Hayward c4025); Vinyl liner replaced last year
28 hours post Shock (pool looks the same- green, a little cloudy)
Free chlorine now 10.5 (with total chlorine 10.5)
pH 7.8 (despite recent dry acid)
Total Alkalinity 66 per pool store, but 80-90 with my Taylor kit (repeated a couple times)
Cyanuric acid 73 (chlorine pool)
Iron/ Copper 0.1/ 0.2
Phosphates 257
TDS 700
Calcium Hardness 199
