What model IntelliChlor do you have?
Intellichlor IC40. Signature updated.
Use PoolMath. "Effects of Adding" --> "SWG"
Today's testing show my TC and FC both under 1. Very little color. Thanks to your tip, I plugged the below into PoolMath:
- 1.4 24 hour SWG output (based on this thread)
- 40% SWG at 18 hour run time
PoolMath says that should raise FC by 2.0, but I'm pretty sure that's not happening. I've been testing TC and FC the last couple days and it appears to be dropping (today was the least color). Yesterday I logged it as a 1.
I tested CYA again with proper temperature and the dot did not disappear (last time zero cloudiness too with colder water and Pool Store had it at 5), could I be needing stabilizer? Based on the
Chlorine/CYA chart, looks like I want to target 70-90.
That's a massive hot tub!
It is pretty big - that number might be high. I've been meaning to do some geometry on it (at least its' rectangular
).
With a SWG, chemistry management is very easy and costs should be minimal. You may need to add a little MA once a week. Might need CYA, calcium, and salt once or twice a year.
I was buying what I felt like was a lot of MA from my pool tech...it might have been that he was charging me $25/gallon! Now that I know how easy it is to clean that sensor and buy MA at the hardware store, I should stay be able to avoid feeding unnecessary MA. I've got a sunk cost on that equipment, but as I mentioned there's multiple parts requiring *annual* replacement. We'll see how the wallet feels when the time comes. I'll have a much strong sense of the "value" by then too.
