Hope everyone is having a nice almost-Summer so far!
I think I might have done something foolish. In my quest to get our pool opened as quickly as possible (think swamp), I tested my ph and then began adding hypochlor (48% from Walmart left over from last summer) as suggested by the pool calculator to hit '10' for shock. That was last evening.
So, today, I realized that I didn't really take my own CYA reading, and when I did it today, I used the entire bottle of solution and could see the black dot (TF100 kit). My question is, I know that the FC level in the pool is atleast a 7.5 (that's what it dipped to before I added more to bring it back up to around 10), and I know that the CYA test can be thrown off by high levels of TC, right? How do I know whether or not I truly have no CYA left in the pool? I know that the calculator actually views "0" as a "1 or 2" right? (Thankfully, it's cloudy here today)
Most current numbers:
CC= 4.5 (stinkin algae!)
pH= As of last night, low normal I think 7.0
CYA= ran out of solution and it was still VERY visable
Thanks heaps for any help!
