Title: MPS use on the same day as Dichlor
Post by: AstaLaVista on November 20, 2007, 12:13:18 pm
My salesman told me not to use MPS and Dichlor on the same day stating that they cancel eachother out.  From what I read on here a lot of people use it together.  What gives? :-/

You got questionable advice.  Are you using MPS for shock, and chlorine for sanitizer?

That is how I was doing the Bengal I had.. MPS to shock once a week and then Dichlor after each use and running a cleaning cycle.  That is all I did.. and the water stayed great.  When I switched to the Vista the same sales place mind you.. they said that because the Vista has a stronger Ozonator.. I would be better to switch to an ounce of MPS after every use, and shock once a week with Dichlor.  I am unsure if I like that idea.... I really like the idea of checking my dichlor level and knowing a have a certain level of FAC.

AHHHHH, the original advice was good, the second method they gave almost always leads to water issues. Switch back to your old method and you'll find that all will return to the way it was, easy and effective.

You know the old saying "eat where the truckers eat". My advice is to "sanitize like the spa professionals do on their own spas". Most all the people I work with that own spas use the simple Chlorine per use and shock once per week (shocking with either MPS or chlorine).

When they delivered our Vanguard this summer I was given the same advice you were.  MPS after each use and chlorine as a shock.  Talking to some Hot Spring folks in here, they said go ahead and do the chlorine after each use and shock with MPS.  I, too, like to be able to see the results of adding chlorine.  Using this method I haven't had any water problems.  Knock on Pinocchio's head.

Based on the good advice I have received on this forum, I think I am going to do the same... Dichlor after every use, and MPS once a week.  Thank you everyone!

We purchased a Sundance Cameo back in June.  It came with 250mg ozonator.  Our dealer recommended MPS after each use and dicholr shock one per week.  That's what we did.  We had water issues within the first month.  Drained and filled and continued what the dealer recommended without any problems for 3 months.  We just did another drain and refill last week and based on what I've read here, decided to go dichlor after each use and MPS shock weekly.  Just wanted to compare and see if things go any differently.

FWIW I use dichlor after every soak and MPS once a week to shock for 3 weeks.  On the 4th week I shock with dichlor.  Works fine for me with on ozonator and N2.

My dealer also said to use MPS after every soak and to shock with dichlor.  I had water problems with that routine.

MPS is also expensive!

Did you have an ozonator on your Tiger River, because ozone is an option on the Tiger River models.

I had the UV ozone on the Bengal.  The Vista has the Fresh Water III CD Ozone.. ?? I think that is what it is called anyway.  The salesmen said it was a more powerful ozonator, and that was why the change in care.

There is something called enhanced shock which is dichor and MPS together. I sometimes use MPS then dichor back to back when I haven't shocked for a while and haven't used chlorine for a few days.

FWIW, dichlor and MPS do not cancel each other out.

My dealer (Caldera and HS) told me to add dichlor daily around  1 &1/2 tsp and put in 1 tbs after each soak and shock with mps weekly. I had great water for a little over 2 months and I had to dump it yesterday. I was adding the dichlor and the mps together if I soaked. Now I'm going to use the dichlor daily and shock with mps weekly. I'm hoping to make it through the winter.

[glow]MPS is also expensive[/glow]!

That's the reason I do the same thing.  My water has been great with this system.  I also have Ozone and use N2 (HS version)

There must be something to this.  I heard the same advice regarding my Arctic Summit.  I have the Peak Ozonator, which is really strong.  But from day one I heeded the advice of many on this forum and dose with dichlor after usage and shock with MPS weekly.  My water is always fantastic, and I am a total know-nothing goof when it comes to this stuff.  So obviously that method is fool-proof.  But I still wonder why salesman recommend the other method when running a strong Ozonator?  Is there something we are missing?

Could it be that the dealer hopes to make more money on future chemical supplies.  A dose of MPS is substantially more expensive than plain old dichlor.

Ok, now I am confused.  I use reserve and renew.  Reserve is sodium bromide which as I understand combines with renew which is mps to make bromide.  Am I right?  The way I understand, I put an oz per person after soaking of mps and add renew once a week.  Is this a recipe for disaster?
Title: Re: MPS use on the same day as Dichlor

No! Bromine is a different system than chlorine. Every time you shock with MPS you are reactivating the bromine (assuming you have everything correct in using bromine). Chlorine can't be reactivated so MPS just oxidizes and doesn't kill anything the way bromine/MPS does.

I agree with the others with the $$$$$ aspect - MPS is expensive compared to dichlor ... it's almost worth it to use dichlor to shock/reactivate the bromine - much cheaper. The only problem there is a bromine tub with stabilizer - I don't know how stabilizer affects bromine, but I guess some people use dichlor in their bromine tub without an issue.

The Reserve/Renew bromine program is a very good bromine method, though more expensive than bromine tabs or chlorine.  It is the exact same as Rendevous Enhance/Activate (LeisureTime and Rendevous have the same parent company).  You can read about it here:

http://www.rhtubs.com/store/enhance-activate.htm

This doesn't have some of the issues other bromine or chlorine programs have and you can use it with ozone and/or a Frog.

We got similar advice from the dealer as other posters: MPS after every use and dichlor once a week.  We have a Jacuzzi 470 with the corona discharge ozonator.

After only one week, we had cloudy water- I had been testing every day but forgot to test that morning and we soaked that night. Unfortunately we didn't realize the condition of the water till we'd been soaking in at for at least 20 minutes because it was full dark outside. It had been at least 24 hrs since we had put any MPS in and since it was less than a week old, we had only added the original double dose of dichlor suggested by our dealer and none since.

I came up with a lovely case of hot tub rash within a day of discovering the water had gone over.  :P  Needless to say, we drained the tub and started over with dichlor.  I went over a ton of posts and gleaned a lot of info from this and other boards.    Hopefully we're now on the right track with 1.5 tsp of dichlor after each soak, and shocking with MPS once a week. The water has been crystal clear for the past week, and I test daily because I'm now super paranoid about the water going bad.  Especially since we have our kids in there every few days- I'd hate for them to get the rash I have (which I"m wishing would heal up soon so I can go back to soaking!)
