Now that I have decent testing (I love this kit!!!), I have a question. Can I get a 2-week break with no testing or chemicals added?
My overall goals are:
1) safe water, always ready for swimming (i.e. never an in-season SLAM)
2) do it at lowest safe cost, and
3) be able to leave it without care for 2 weeks.
My pH creeps to 7.8 and sits there for a couple more days, but then gets to 8.0. I haven't had the courage to go beyond that, so I don't know how long it takes to rise above 8.0. My method has been 1 cup (250 ml) MA every 3 days to stay within 7.6 to 8.0, though with my new K2006C kit and corrected CYA, I've lowered the SWG setting because FC was higher than my past readings. I then tried dropping pH to 7.4 and I was good for 4 days and back to 7.9.
I don't know if I'll be able to do borates, so I'd like to leave that option off the table for my first year. I'll try a cover later, but for now, we like to look at the water and I know having a cover on it will change a lot of this. I'd like to figure this out in terms of water chemistry for now.
My TA seems to like to be at 90. Iíve tried dropping it, but then up it goes and sits again at 90. Maybe this is because the pool is new.
So can I set the SWG for what the pool needs in hot sunny weather (knowing FC will be high if the weather is cloudy), and then take the pH quite low. How low is the lowest you would go with your own pool?
Or would it be better, or even possible, to set the SWG a bit lower, keep the CYA on the low side, and chuck some Trichlor pucks in the skimmer to hold the pH? Do they even last that long?
Is it feasible to stretch that to a 3 week break? 4 week break?
I'm trying to figure out what methods I can test while I'm here, before I need to use the two-week break. If it's not possible, I'll have someone checking on the pool every few days, but I'm hoping to find a way that doesn't involve 32% acid and water chemistry wild cards, and leaves them safe to have a dip in the pool!
Latest numbers are:
Thanks so much for all the help so far!
