Got our pool at the end of last summer, July. Started following advice and reading everything on this site. Had zero problems. Have a cheaper test kit that will measure CYA, etc. and had no issues with it last year. Just ordered the better test kit for this year.
Pool is full and pump is running. Numbers according to my cheap test kit, hth 6 way strips:
Total Hardness 200
pH between 7.2 and 7.5
TA (hard to read) but over 240??
CYA (reading shows a bit over zero, kept about 25-33% of the water from last season)
Water is crystal clear, bottom has very few leaves, organic material, etc. Could get it out with vac pretty quickly.
My question is...should I shock the pool or raise the FC and CYA gradually? Last year I used bleach and some trichlor tabs in my skimmer. I know the trichlor will raise CYA as will "shock" (at least what people call shock). My test kit is probably not accurate enough for the overnight test. I think I know what I am doing, just looking for some verification. Don't want to mess up my already clear water.
Any advice on how to proceed.
