Help with my pool numbers...

I think your TC and FC is misstated. That would give you a CC of 3.0 which I have never seen before. That's why JohnT is telling you to shock.

My guess is your TC is 3 and your CC is 0 so you would not need to shock, if that's the case. In fact, probably shouldn't 'til you resolve your metal issues.

With a CYA of 100, once your water temp gets above 50 or 60, you're going to be fighting algae---with CYA that high, you need Cl closer to 8-10.

In your quote, do you mean FC instead of CC? If not what is CC?

Total Chlorine(TC)=Free Chlorine(FC) + Combined Chlorine(CC)

Combined chlorine levels over .5 indicate the need to shock the pool. Combined chlorine is chlorine that is "involved" with biological contaminants and is usually the cause of the chlorine smell people complain about.
