Hello! I am a newbie (bought a house with a pool 2 months ago) and am confused at these latest test results (well, generally confused about pool stuff but extra confused today!). I read through almost all Pool School today while trying to watch my 1 and 3 year olds so it may not have all sunk in.
FC = 6.5
CC = 0.5
Ph = 8.0
TA = 130
CYA = 0 (I think, no cloudiness apparent)
Water looks clear but I have been noticing a chlorine smell on and off (I have a very sensitive nose though).
And these results are after I added in 1.5 litres of muriatic acid earlier today as my pool store test showed PH of 8.2!
I hadn't tested with my kit in a few weeks and the results have changed so much in that time. I had been cheating with pool store test results in the mean time as I wasn't confident in my own testing abilities yet and their results (just from yesterday) were so different to mine. I know I shouldn't worry about their results but it showed CC of 2.0 and CYA of 30. Since I'm new I feel like I must be testing wrong if my results are so different from theirs!
Anyways - what is most urgent here and the main question - can we swim??! This is probably the last week of nice weather up here in Ontario so we were hoping to get a few more swims in!
Pool Calculator says I should add 1.5 more litres of muriatic acid which I can do in the morning. But I need 557 oz of liquid stabilizer?! Should I bother since we'll be closing in a few weeks?
Isn't the high FC and non-existent CYA confusing? My pool is very shady, directly in front of a tall forest so maybe the lack of direct sunlight keeps my FC high? My SWG is at 60%, should I just lower that or have the pump on less to bring down the FC?
Sorry, very rambling post. I'm tired and confused. Thanks for any help/support!
