Alright well I got my used 230gal tub purged with ahh-some 2x over the weekend. The first round got all kinds of gunk out! The second round only had a little bit of gunk. I skimmed it off the foam, and continually cleaned the sides and water lines until it stopped producing anything at all, then the last drain over night sat. Sunday morning was a deep clean, rinse, and fill.
I then tested my new clean water before adjustments and had:
CH: 80
TA: 80
PH: 8.0+
I worked on CH first, added 5tbsp Calcium in an attempt to raise it to 150, I then added 2oz MA in an attempt to lower TA to 50. And finally added just over .5oz dichlor to try and get FC to 10. I then closed it up after an hour and let it be overnight.
This evening when I got home from work at 5:30 I ran my tests again and got:
CH: 150 (right on the mark!)
TA: 70 (not much change with 2oz, only 10ppm)
pH: 8.0 (still high)
FC: 6.6
CC: .4
So I added 2oz more of MA to tackle the TA and pH. I waited 3 hours then tested again and got:
CH: 150
TA: 50 (it worked!)
pH: 7.2 (just a tad low but I did not aerate before testing)
FC: 6.6
CC: .4
Even though the FC was a bit higher than 5ppm I went ahead and took the inaugural soak. I couldn't wait anymore, this project has been ongoing since June! The outside air temp was 40, the tub was up to 102, and it felt FANTASTIC!! I soaked for exactly 1hr by myself with swim trunks, (I don't have any means of privacy just yet, next project!) and then tested FC again to get a baseline for usage:
FC: 3.6
CC: .6 (not sure why this raised a tick, is it supposed to?)
Once I was all done, I added 3.1grams dichlor which pool calc says should raise FC by 2ppm so should have put me back to 5.6ppm.
I'm looking for opinions on everything, hopefully I did this all correctly?? Will the CC continue to rise? To be honest I don't really understand the combined chlorine just yet. Does 3ppm FC consumption per bather hour sound correct for a small tub like this? Will I have to go up past the 5ppm FC if my wife is to join me and make it 2 bather hours in one setting? That would mean a consumption of 6ppm leaving the FC to hit 0 before were done if we stay in for one hour. If thats the case do I bump the dose up prior to compensate? Is that safe?
Do I need to continue testing the CH & TA each time, or can I move that to the 1x per week testing and just daily test FC & pH?
And finally what do I do now to just maintain? Obviously I add dichlor each day to keep the FC up so it's ready to use, and when done soaking replace what has been used, but then what??
Thanks for the help!
