Hello, new here, and a new pool owner. My water is slowly turning cloudy white to slight green. I suspected low chlorine so I increased the rate on my pentair 320 feeder for the past few days. Still no improvement.
It turns out the tests yesterday showed 0 ppm free, total, combined chlorine. So something is wrong with my feeder. I have 4 3" tablets in, jacked it up to full flow, and ran it for 16 hours. I tested this morning and there's some chlorine, but not enough to really note. Do I have to just be more patient? The Pentair manual said switch to 1" tablets as the dissolve faster. Thoughts?
Also, in inspecting the unit, the 5/8" OD chlorination tube is done. It was brittle when I took it off, but cracked when I tried to get in back into place. Is this a standard hose that I can buy anywhere (cut to length) or do I need to get the specific oem part (R172091)? [Edit] Turns out the screen was brittle as well. I went to take it out to clean it out and a few pieces broke off. I'm guessing this is a special part that I have to purchase the OEM part from a pool store. Any insight is greatly appreciated. The pump is currently non-operational until I fix this.
Rest of specs on my pool (let me know if other info would be helpful):
20k gallon plaster, less than 10 years age
Saturation index 1.71
Water color none
Water clarity clear
Free chlorine 0
Total chlorine 0
Combined chorine 0
pH 9.0 (I added 1/2 gallon muratic acid yesterday to help, looks like about 7.5 today)
Hardness 350 ppm
Alkalinity 110 ppm
Cyanuric acid 100 ppm
