Hi everyone,
I really appreciate the respect that the experienced members show the new guys.
Here we go...
My CC has been zero for a couple weeks, but I don't understand why I keep getting what I think is algae regrowing on my liner.
A quick description of what I think is the algae: you can turn it into a cloud and basically clean off the liner by waving your hand around it, so it is not "attached" to the liner and a couple days after cleaning it, you can see that where it "grows" back it shows the outlines of where the pool brush was last used (you can see the streaks from where the bristles on the brush contact the liner).
I only have two days worth of test results to show and they are almost a week apart because when I first started testing and wasn't recording the data, I didn't see ANY change in my chemicals and I was happy enough with them so I extended the time in between tests. Also, it is raining right now, so I didn't want to go test it today.
Test results:
6/25:
TA-140
pH-7.5
FC-7.5
CC-0 (there was no change in color when I added the solution after testing the FC with the TF kit that's all I am looking for right?)
TC-7.5
Calcium Hardness -110
CYA - 50
6/30:
FC - 5.0
CC - 0 (same thing, no change in color after adding the solution when the FC test was completed)
TC - 5.0
pH - 7.5
didn't check anything else this day
I KNOW everyone says to check often, but without adding ANYTHING, my chlorine dropped from 7.5, which it was at for a week after my initial shocking, it only dropped to 5.0. I know the TA is a bit high, but I didn't think it was ridiculous and I believe the Calcium is low, but I didn't think it was the biggest deal.
Last year I used "Yellow Out" for what I believed was Mustard Algae and it worked well after attempting to battle it for a couple weeks (thats primarily because I did think it was pollen). This year the algae is much darker but still "fans" off of the liner like the pollen looking algae from last year, so I don't know how to classify it to treat it.
When I shocked the pool earlier in the season, I didn't have the test kit, so I started out with a generous amount of powder Cl and added some more two or three times a day until the water was completely cloudy blue.
Since my CC has always been zero and I am not losing the Cl quickly, I don't know how to accurately shock the pool. I do think that the "growth" was slower when the Cl was 7.5, but it still grew.
I would LOVE to use my pool on this July 10th and with my Cl dropping so slowly, I didn't want to do anything outrageous this week because with a vacuum, it looks fine with crystal clear water. I might have to wait until after that to do anything to the pool.
I use a solar cover and I believe that helps with the Cl retention and I only get 4hrs direct sun.
I appologize for the lengthy post, but I was hoping to give all of the info.
Thanks,
