Hi all! First of all this is my first time on here, and thanks in advance for any help you can give me!
A couple days ago I just filled our 1500L hot tub for the first time. We just bought our house in the beginning of the year and the hot tub was currently running and maintained by a spa service. Then we had it drained as we were not living in our house and weren't going to use it till this fall.
So I cleaned out debris, filled it up and added a cleaner solution to it, put the pumps on high for an hour and then drained it and rinsed it and drained it again. Then I filled it up again. I tested the fresh water with the following results:
FCL 0
TCL 0
Alk 180
pH 7.5
TH 100
Then I filled the chlorine floating dispenser with fresh pucks/tablets and unscrewed the top to open the vents to about the "3" mark on the stem as recommended by the local spa store. Next day I did another test:
FCL 0
TCL .5
Alk 180
pH 7.5
TH 100
So the chlorine levels were very low even though the dispenser was floating around. So after doing some research I found that one must also do an initial shock to fresh water on the first fill. So I did that, then tested right away:
FCL 10
TCL 5-10
Alk 180
pH 7.5
TH 100
So that was much better, obviously too high to swim in right away. But the instructions on the ZAP Oxydizer said one could swim in it in 20 min. A couple hours later I decided to increase the hardness by adding a hardener substance. This seemed to nicely put the hardness at around 250, tested right before we went in to the tub last night and I thought the following numbers were great:
FCL 3
TCL 3
Alk 180
pH 7.5
TH 250
Last night I took the floating dispenser out while we were in the water as I heard one must do, but not sure about that, then put it back in after we left.
Today however, chlorine levels are way back done to nearly nothing like they were when I initially had the floater in
FCL 0
TCL .5
Alk 180
pH 7.5
TH 250
So I have cranked open the vents on the chlorine floating dispenser to "8" instead of 3, hoping this will dissolve more chlorine into the water. I'm not sure what these numbers mean, and tried to Google it extensively without much help, I first thought they were referring to the ppm of chlorine desired. The numbers go up to about 12 I think.
Any suggestions? Will the 8 level work on the floater? Thanks!!
