I've been having a tough time balancing my pool. It's my first season with a pool, so I'm still in the learning curve, but I would like to bounce my concerns off you and see if that can give me a new idea or mindset...
My tf-100 numbers first:
FC (failed an OCLT last night): 4.5ppm at 8pm. 2.0ppm at 5am.
CC: 0.0 at 8pm. 0.0 at 5am.
The water is clear, but since I failed the OCLT I told the wife to not let the kids swim today and pumped up the FC to 12ppm (per the FC/CYA chart)...following the process. More brushing and testing this evening.
Here's where I need a sanity check, am I doing things about right?
I'm been running the pump for 12 hours a day and I've got my SCWG at 85%. My FC keeps slowly lowering and I've been supplementing with bleach more frequently than I'd like. We've had a ton of sun and a ton of rain lately in Central Florida, so I realize I'm burning off chlorine (sun), and decreasing CYA (rain and drain off/splash out)...a double-edged sword.
Does my pump time and SWCG level seem about right for a pool in CFL? Seems like too much run-time to me, but I don't have any basis for comparison. I've been trying to up the CYA level, one sockful at a time, and when I test, I re-run it a couple of times to verify the value (the reagent is about 3 months old).
I don't have any ladders or rails in the pool. But do have a wide rock faced spillover from the spa to the main pool. I keep up on brushing the rock, but there are many 'nooks-and-crannies'. I'm hoping that when we designed and built the pool we didn't create a permanent and unchangeable home for algae. Anybody else have a rock spillway? Do you do anything in particular to keep it clean?
Or perhaps I just need to make my way through another SLAM....but then I'm afraid my FC will creep down again, and I'll be back in the same position.
What bugs me too, is that I've read posts here from folks that say they haven't SLAM'ed in years...is it just that these people have such a deep understanding of their chlorine that they can predict when and how much to add?
Very much appreciate your input! Thank you
