Hi - I purchased a house last summer that has a 25k gallon plaster SWG pool, and kind of just coasted w/ testing and chemicals through the end of the year into Winter without any issues. When Winter hit, and my SWG went dormant, and at the previous owners recommendation, I threw in a bunch of chlorine tabs into the floating chlorine dispenser, and kind of just let it be. Now that spring is here, my water has a slight cloudy haze to it and my levels are off after testing (using the TF-Pro Salt with SmartStir), and so I know that I need to add a bunch of stuff to the water to get everything back in line (which I have purchased already), but wasn't quite sure of order of operations in terms of what to do first, as well as whether I should SLAM or not, given my levels.
First things first, here are my current levels and what pool math says I need to add to bring my levels into line (not taking into account that my water does have a slight cloudy haze, which from reading means that I most likely have algae):
FC: 1 <-- Add 2 quarts 10% liquid chlorine/bleach to bring FC to 3 (or if I'm going to SLAM, approx 2 gallons to bring to 12 w/ CYA levels at 30)
CC: .5
pH: 7.5 <-- Good
TA: 70 <-- Good
CH: 175 <-- approx 64 lbs calcium chloride to bring to 450
CYA: 30 <-- approx 9 lbs dry stabilzer to bring to 75
Salt: 2400 <-- approx 250 lbs of salt to bring to 3600
From reading the forums, I know that I should start w/ adding half the recommended amount, wait 24 hours and test again to see where I'm at, then add additional if needed. Is there a recommended order that I start adding the above items into the pool, or should I just start from the top and work my way down?
In terms of SLAM for my pool, from searching the forums, it seems that it is recommended to SLAM if you have a CC of over .5, and you have evidence of algae. In my case, since I'm at .5, should I just add enough chlorine to bring my FC up to 12 (per pool math, which I realize could change if I add more CYA first), and see what happens, or would you recommend I SLAM? the cloudiness is very faint, but it's definitely there.
Thanks for any advice, and hopefully I'm posting in the right place. If you need any additional info, please just let me know.
