Hello! This is my first post! My family just had a new pool installed last month and we’re finally on the home stretch! I’m enjoying learning about all the ins and out of pool chemistry as I have a background in biology/chemistry. I included the description of the pool in my signature (18k gallons, fiberglass with SWG). Current test results:
FC: 7.6
CC: 0.6
CYA: 80
PH: 7.2
Alk: 250 (was 330, have already added a ton of muriatic acid over the past week)
CH: 390
SI: 0.4
I’d like to SLAM the pool tonight as we had a long period of low chlorine (turns out CYA had dropped to 0 and FC didn’t creep above 0.5 for over a week). CC is getting up there, and although the water is clear, I noticed a little green today around a couple of my light covers. I wanted to do liquid chlorine, but only had access to HTH Super Shock 53% cal hypo. According to the calculator, I need to add 6 lbs 11 ozs. Questions:
Can I premix with water first then dump to make sure it dissolves (directions just say to broadcast in deep end)
Should I be worried about increasing CH? In the future we will most likely use liquid bleach, but we’re close to the end of the season here in Michigan so pickins are slim.
If I just add 6 lbs should that be ok? They are 1 lb bags.
Will I need to worry about shocking often with the SWG? When should I shock vs superchlorinate?
Once FC/CC is in a good spot, I plan on tackling the TA. Thanks for your help!!
