Hot Tub Water Woes
Certified106:
So after draining and refilling it last night I started the same viscous cycle as last time.
The PH and TA were off the charts high. PH was over 8.0 and TA was over 240. I dosed the tub probably 4 times over 2 hours to try to bring the TA down. Went to bed got up and it was still off the charts. I dosed it probably another 3 times before leaving for work and the TA was still crazy high and the PH is now extremely low. This is getting really frustrating........... >:( everythign I have been reading makes it sound like this shouldn't be happening and they should both come down together but yet it does this every time.
If I get the TA in range it is impossible to get the PH up at all. The minute I try to bring PH up the TA shoots up above 240. I am about to give up on the TA and just get the PH where it should be and to see what happens. Shoudl I be using soemthing other than the @ease strips? Is there a better more accurate way to test this thing. One last thing the test hor hardness was showing about 50 so it wasn't as high as last time I filled it.

A drop test kit is more accurate than test strips, but test strips are what I consider good enough. The amount of pH increaser needed to bring the pH back up shouldn't be enough to skyrocket the alkalinity.

Again you over did it. I am assuming you are using PH down or decreaser? So what happened is you added so much that finally the PH dropped out. Now to have high alk and low ph does not make sense, but it will do it in a hot tub. My water comes straight out of a well, my PH/ALK is off the charts also.
When I do a water change, I might add like a cup of decreaser, and wait a day. Then check and add one more. Then I just leave it alone. High PH/Alk is not the end of the world! I have never had scale and my water stays crystal clear, until I get lazy with sanitizer and it goes cloudy one me.

Ok, I kind of wondered if I should dose it that much....... Chalk this one up to learning experiences also. If I can do it wrong I will LOL.
Basincally when I changed the water I wasn't sure how long I could go with no shock and no SmartChlor while trying to adjust the water before I started having other problems. Before I left for work I shocked it and put the Smart Chlor in it and when I get home I will check it again if it needs it I will make a small adjustement and not check it unit the next morning. When you read the manuals it makes it sound like instant death by scale if the PH gets high at all.

Hi, if I haven't said it yet, welcome to the forum. We use to have a member here, who was in the industry a long time, he always use to say, and we started calling it Chas' law, that every new user should dump there water after about a month because everyone over does it and messes up the first time. I know I did 13 years ago.
Other's here are more qualified to assess the situation, but I will say my water is always clean and I dump about every 3 months. (2 adults use the tub almost every night.
My only advice that I think it worth anything, don't over worry about PH. Your skin will not fall off. Most of the chemicals you add to change PH say to wait several hours before adjusting again. I say, wait 48 hours. If you add more too soon, you start chasing the PH reading high and then low.
