Run around at pool store

[miker1755]

I wrote a detailed explantion of where I am but lost it! I think I have posted my pool spec 2 times and clearly don't know how to edit the info. Bottom line is I got the 6 way test from Wal mart with the following:

• Cl=5.0 after adding some granular Cl as the reading was 0.
• pH=7.3
• Hardness 540
• CYA 90+
• Alk 110

Tap / fill water:

• Cl 3.0
• pH 7.6
• hardness 170
• Alk 230
• cya 0

I am waiting on your recommendation with bleach and borax in hand. My pool is 17500 gallons 19' wide x 35 ' long with 5' depth in the middle & 3.5' at both ends. 2 hp pump, Nautilus ns-60 DE filter, Polaris 380 cleaner with booster pump.
