I have a 18x52 round intex with a sand filter. I have just finished filling it and the pump has been running for 1 hour. My water tests results are a little wonky and I am not sure where to start. I have never owned a pool so I have no bad habits to break. I have read through pool school and have a basic understanding of pool chemistry but mainly want to get off on good footing to help prevent issues.
FC is 0
pH is under 7 - I guess 6.8
Base demand was 10 drops to get is to 7.3/7.4
Water Temp is 74 degrees
TA is 425
CH is 275
CYA s 0
I have 10% liquid bleach - Will be getting Borax shortly
What do I do first? Add bleach to prevent algae? Deal with my low pH? High Alkalinity?
Thank you so much for the help!!
