Hello everyone. First post here. Great and very helpful site. I have spend a few hours reading the recent posts this past week trying to get on track with everything. This will be my 10th season with the in ground pool I have. Everything has been going well with it over the years. But I have noticed that the last few years it's taking longer and longer to get the water crystal clear when opening. This year it took 2 weeks and I used much more clorine that I have in years past. 25 gallons of 12.5 percent liquid and around 25 pounds of 3" tablets. Plus 60 pounds of baking soda this year so far. Been open 4 weeks. Right now the water is looks great. I wanted to add I haven't changed the sand in the filter yet after 10 years.
I picked up a TF-100 test kit this past week. Results below.
What do you think ? Thanks for any input. I tend to overload the pool with clorine and let it go down low and repeat.
Thanks for any and all input. Greg
I edited the results to correct the TA reading
