So i just filled up my new hot tub, after running Ahh-some through it. Very surprised at how much gunk was coming out considering the hot tub was manufactured within the last 5 weeks.
THen drained, rinsed and refilled.
Added roughly 3 ppm chlorine(did not test to confirm this level was reached), 100 ppm CH, roughly 30 ppm CYA (still will need to wait to confirm this level ends up correctly). Added Spa Marvel. Ran jets for the 20 min cycle. let hot tub sit with just the circ pump and water fall on for a few hours.
FC 1 ppm (chlorine was purchased in April, so could be a bit weaker)
Alk >200 ??? Not sure why so high
CYA not tested yet, will wait a few days for it to disolve
So added about 100ml of Muriatic acid last night and put the jets on 20 min cycle. This amount should lower my pH to 7.0 based on on water volume
My question is.
Will 20 min cycle be enough to raise pH back up, or will i need more time? It was late, so after 20 min i closed lid and went to bed. Will check tonight, but just curious.
I'm wondering why my TA is so high, maybe reagent is bad? it is so high, i stopped at 20 drops. I will need a lot of Acid cycles to lower and then raise pH. Maybe tonight i can do a few cycles?
