Yep, you need to get your chlorine up asap, but lower your pH first!
Remember that you will need to add chlorine each evening. Always add enough to get you thru the next day.
With a CYA around 30, you should never let the FC level fall below 2, target 4 to 6.
So, in the evenings I suggest you add enough bleach to raise it to 7 or 8.
Also, I suggest that you only monitor your TA for now and do not try to lower it.
Because you are using so much muriatic acid for pH control, it is bringing down the TA.
It has dropped from 200 to 150.
Just to be clear, you need to add bleach today/now to get your FC up around 4 or 5.
This evening, bump FC up to 7 or 8.
