Greetings all....new to this forum but not to pool problems...
All has gone reasonably well for the last 6 years of pool ownership...but in the last two weeks I've been stumped. My AquaRite SWG does not seem to be working properly OR I have a yet undiscovered problem with my water chemistry (according to the rude customer service reps at Goldline). Here are the stats: 30K gallon IG plaster pool (6 yrs old), DE filter and Aquarite SWG with 2 yr old T-15 cell. Pump operates 10 hrs per day at 65% setting....and has for 2 years with no problems...till now. No changes in types and amounts of chemicals routinely used.
FC 1 (by addition of bleach last night, otherwise "0")
TC 1
PH 7.6
TA 100
CYA 80
Salt 3800 (SWG reads 3400)
Phosphates .1 ppm
Had the cell tested due to no production of chlorine...cell tested bad at one shop...tested good at second. According to readings at electronic unit (and Goldline), chlorine production is taking place. After reinstallation, a FC reading at return (undiluted by existing pool water) is 2 ppm...with pool water at .5 ppm.
QUESTIONS:
Have I missed something in the pool chemistry that is causing my recent lack of FC?
Is my SWG generating an "appropriate" amount of chlorine?
Having read through this forum and Pool School, should I be targeting my FC at 4 ppm instead of 1 to 2 ppm?
Sorry to go on in such depth, just tried to give enough info to let the experts have enough ammo to answer. Thanks in advance for your assistance...have learned ALOT so far!
