Hi guys,
Big fan of the TFP method - for 2 1/2 years! Have not had to shock/slam at all!
Two problems left:
1. Calcium scale (been there since previous owner kept CH at 400 per pool store advice). I keep the CH low and the scale isn't getting any worse, maybe a little bit better.
Should I do anything about this? The scale doesn't seem to be any rougher than the pool surface itself.
2. Blotches appeared on steps. Tried scrubbing, placing a 3" chlorine puck overnight, still there.
Any ideas what to try next?
Here's the chemistry and some pics. (yes, those are footprints in the deep end. I don't know how or why!)
FC: 5.5 (keep it consistently between 4.5 and 5.5)
CC: 0.0
TA: 90
pH: 7.8 (keep lowering it to 7.6 but this pool wants to drift up and stay at 7.8)
CH: 175
CYA: 38 (as close as I can tell)
Thanks,
Steve
