Okay, I understand, now.

I would recommend adding enough stabilizer (also called CYA or Cyanuric Acid) to get to 30ppm. Dosage will be on the container and you can get it at Lowe's/HD or any pool store.

I would also add 10 lbs of baking soda to get somewhere around 100ppm for Alkalinity.

I would up the Cl just a little and keep it between 3-5ppm.
