Day 12 - Hour 0 - FC:>60?? CC<1 CYA:31 PSI:15
I think there's something wrong with the R-0871 or DPD powder reagents I just started using from TFTestKits. It took well over 60 drops in a 5ml sample for the deeply red, almost-purple color to change to clear. I bought the 2oz bottle, and it's labeled as R-0871. My chlorine level can't be 60ppm, can it? I added less than a jug yesterday. This is my second replacement container of DPD powder.
I don't know what to do in regards to chlorine. It's a bummer, because it undercuts some of the victories from the overnight improvements. In the shallow end, the pool has much improved clarity all the way to the floor:
The light fixture (albeit broken - how do I replace the bulb!) is visible and so is the full ladder.
You can barely make out the main drain. No evidence of gator:
I can finally see enough of the pool floor in the deep end to scoop non-blindly!
And can see the bottom of the skimmer clearly. It looks like that's a swing cover over the skimmer/vac port, but what's the other closed-off port for?
And here's my first sample. I did it twice. After the DPD powder it turns this deep color. Seeing how deep it is, it makes me realize it's probably the DPD powder that's questionable. Is there any chance I did the test wrong, or the presence of cellulose fiber has affected the outcome? Or is there any chance in fnord that my chlorine level is at 60ppm? If so how? I can haz confused?
Here are the stats on my pool pressure:
Baseline PSI: 10
Cellulose Fiber PSI: 11
Meter PSI: 15
Current PSI: 12
I backwashed and the PSI only dropped to 12, so I backwashed again with no additional PSI drop. Is it possible some cellulose fiber I added is still in there and has spread or resettled?
At this point I'm not going to touch the pool until I hear back from an expert. The chlorine reading is befuddling, especially since it's proven to be so consistent for me in the past.
Lookin good, how much cellose fiber you put in?
I use it too, love the stuff, clears the water very quickly
I think it was around 10 cups before the pressure had risen 1 PSI.
