Just seems strange

My ch is down to 1.2 in a 13k pool. Went as always to pool calc and since I don't have bleach high enough I just insert 12% which I have. Also ph is 7.8. Ok now I poured in the muriatic acid but the calc said 37 oz of ch OR 4 oz of 73% calcium hypo. Maybe I'm reading too much into this as it doesn't seem enough to raise my ch to even 3.8. A little assistance please

In a 13K pool, a quart (32-oz.) of 12% sodium hypochlorite will add approximately 2.3ppm of chlorine. Use that as a reference to help you figure out doses to add.

will do thank you just gotta get over thinking things aren't enough. Im thinking I'll get an OTO tomorrow
