    Digital testers

    Are there any digital testers for a bromine hot tub? I haven’t been able to find any.
  2. Members 0 79 posts I find this interesting -the owner's manual for my spa gives recommended levels for chemicals and it is quite different from the box of test strip recommendations. Even different test kits show different recommended levels. For instance , bromine 3-5 ppm vs 2-6 Chlorine 2-5 vs 2-4 pH 7.2-7.8 vs 7.2-7.5 or 7.4-7.6 Alkalinity 40-120 vs 80-120 Hardness 50-150 vs 100-400 Maybe this just shows it's not all that critical and there is a wide range of acceptable?
  3. From what I understand, Pool Calc is a device that tests the water and tells you, based on the readings, what to add. (Or maybe you test it yourself and input the values). Can it be used for a hot tub or is there a different one that can be used for a hot tub?

    Chlorine & bromine

    Is it used after bathing or as a weekly shock?

    Chlorine & bromine

    Thanks. I know how to use bromine - a bromide starter packet on fill, bromine tabs in a floater and a shock, but how does one use chlorine- a weekly shock with a little bit during the week as needed? To answer your question , I think it's because bromine has more staying power as a sanitizer but chlorine may do a better job in clearing up cloudy water . Our situation is that we have a vacation rental with stays of 2-7 nts. No one is going to be monitoring the water during their stay. I go back and forth on asking guests to handle chemicals, like having them put in premeasured amounts of MPS or Dichlor after each use.
  6. Recently I called our spa manufacturer with a question and the CS agent said something I'd never heard before and I don't think I believe . She said using bromine and chlorine at the same time is bad and they cancel each other out.If you have a bromine tub and you want to switch to chlorine you have to empty the water and start new.From what I've read , even a bromine tub has some chlorine because of the chemical reaction with the bromine tabs. We have a bromine floater and our hot tub guy convinced me to start having him add a little Dichlor to keep the water clear . Previously we had just been using MPS. And he also still uses MPS. Comments?
  7. Just a floating dispenser
  8. My spa owner's manual says that they don't recommend a floating chemical dispenser and that any damage to components or the shell caused by it will not be covered under warranty . Really? Are they just talking about dings in the shell? But components? The manual also states all chemicals should be added to the filter or close to it . Is that very important/ standard practice?

  10. Is there any reason to use all 3 - MPS non chlorine shock, bromine tabs and Dichlor - or is that overkill? I started out with the first two but for water clarity it seems to help to add the 3rd.

    Question about using TDS strips

    I don't do maintenance myself since this is at a vacation rental 75 miles away. I can check on things when I go every 2-4 weeks. From what I understand, when TDS starts to get to near 2000 , there should be problems with getting the chemicals easily balanced, so our service person should know that and I probably don't even need to check it. He did tell me that most owners try to let it go long to save money on a refill. I'm the opposite because I don't want any illnesses or bad reviews..
  12. At what level TDS do you change out your hot tub water? My test strip says 3000 ppm , but I've read some people do 1500?
  13. I was just going by the control panel .
  14. Our hot tub is barely over a year old. We set the temp at 102 but when we go to it , it is 104.. Is the thermostat already going? Even with a good cover, does the summer sun affect it?
