Hi all,
Here are my latest test results and also my goals for where I'd like them to be. I'd love to hear from the gurus to make sure I'm on the right track.
FC - 4 (generally sitting between 3-4)
CC - 0
pH - 7.5
TA - 60
CH - 280
CYA - 35
Clarity... like bottled water!
I'd like to get my CH up to 350 and CYA up to 70 and leave everything else as is. I'll probably try to target FC at more like the 4-5 range. My pool is still only just over 3 months old so pH is going up constantly but I'm hoping that getting my TA down to 60ppm finally will help a bit (or is it just a lost cause with pH for the first year?). I'm not planning on adding borates at this stage. I understand that with a SWG my pH will always drift up, but I'm hoping at least after the first year it slows down a bit. So goal levels would be:
FC - 5
CC - 0
pH - 7.5
TA - 60
CH - 350
CYA - 70
Pool Calc puts my goal levels at a CSI of -0.48 which seems pretty close to -0.6 (at a pH of 7.4 it goes down to -0.57!). As my pH drifts up to 7.8 the CSI goes down to -0.21 so I'm figuring I'll always be heading in the right direction? Is that the correct way of looking at it or should I be looking to increase my TA a bit? Increasing TA to 70 would have me sitting on -0.38 which seems safer, so I guess the question is whether staying at 60 will help control pH drift enough to compensate for the borderline CSI. I've only just got it down to 60 with current rainfall so it's to soon to for me to tell from here.
I've been running my pump on eco speed, with SWG running between 40-50% for 10 hours a day (7:30am-3:30pm then 8:00pm-10:00pm), but after next weekend I'm going to start reducing that to see if it helps my rising pH.
Thoughts?
Thanks,
Steve.
