I did the CYA test and the tester was filled but I could still see the dot. I'm in Michigan and it's been cold since the pool was filled so the test makes sense from what I've read. Does this mean there's no CYA in the pool?
No, i've been reading and looked at it but math and science were not my strong suits lol. Is the correct FC based on pool size? Thanks to everyone for the help this is my first time owning a pool.
