Yesterday we had algae show up. We have a 14,800 gal pool with Pebbletec and a basic test kit. I just ordered the recommended test kit last night. All we have right now is a basic test kit. I checked the chlorine level yesterday and it was essentially zero. The test water had a slight yellow tinge to it. The alkalinity was 80 ppm and the pH was 7.6.
I back washed the DE filter yesterday and added 1 lb of granular "shock" to the pool at the recommendation of the local pool place until I could bring a sample in, brushed the pool, added more chlorine tablets to the in line chlorinator, and left the pump running continuously. I also added 5 caps of phosfree. Then I started researching and came across TFP.
I took a water sample in this morning to the pool place and these are the results:
FC .13 ppm
CC 1.82 ppm
hardness 211 ppm
alkalinity 59 ppm
CYA 65 ppm
copper 0 ppm
iron 0 ppm
i added 4 lbs of baking soda (I use that instead of alkalinity up) when I got back from the pool store at their recommendation. I am trying to figure out how much 6% bleach to add. I looked it up in how to slam the pool and saw I need to take it up to 25 ppm. I don't have a test kit that can test that high and I am nervous about taking it up that high. Right now the pool water is clear and there is a small amount of brownish algae on the flat parts of the pool. The pool looks a lot better today than yesterday but I know the algae isn't killed.
I would love love any help you all can provide.
