Are these accurate with the chlorine level so high though? It is slowly clearing up since the shock. Will keep backwashing and running filter 24/7 and see how it goes.
Excellent! Yes the kit is more involved, but VERY accurate. No more pool stores and guesswork or you!
Your chemistry isn't bad...the only thing I see right off the bat is that your CYA is double what it should be (50 max). You should start diluting your water to bring it down (drain a foot or two of water and refill with fresh) and stop using anything with CYA in it (pucks, stabilized chlorine, etc).
The fact that your chlorine levels are really high is why it is clearing. You needed the extra boost to overcome the high CYA levels. With a CYA of 110 you need a chlorine level of 43 to shock and a level of around 8.0 mninumum, just to stay sanitized.
Keep the chlorine high and start diluting and thing will rapidly improve.
