I changed the water on Sunday because the weather was so nice and the tub's perfect now. No more foam from that first fill and I've finally got everything the way I want it. The wife informs me last night that her sisters are coming again tonight for another go in the spa.
So this morning I was here:
What I did was to raise the pH to 80 (I was going to anyway) with 3 Oz of Baking Soda which raised the pH to the 7.9 range.
I used 1.5 Oz of MPS to bring the Bromine level up to 10 (I actually got 11.5 but it will be 10 by the time they enter) and this dropped the pH back to 7.7
While they're in there, I suspect with an 80 TA that they'll push the pH up to around 8 to 8.1 which will allow me to put in the 4 oz or so of MPS shock for the 3 to 4 person hours of soaking thus bringing the pH back down to around 7.5-7.6.
So basically I have 3 questions...
Am I doing anything wrong here or is this the proper procedure. Is 4 oz of MPS way too much to put in? With a 30ppm bromide bank, it doesn't seem that I could activate all of it anyway.
What do you all do in preparation for your spa parties?
Am I making way to much of this?
