I recently purchased a USED 2007 Sundance Chelsee spa. I wanted to go with the Cleanwater Blue symptom as I have sensitive skin.
We didn't do a system flush prior to filling tub. The filters were new and the shell was cleaned with spa cleaner.
I filled the spa with softened water that passed through a neutralizer and has some soluble iron/tannins. My base stats are as list below
TDS=300
pH=7.4
TA=70
Calcium= 75
At Startup, I added:
oxyspa=2.5 tbs
diclor=1.5 tsp
Cleanwater Purge=18 ml for metal sequestering
Seaclear clarifier=22 ml
Cleanwarter Blue=22 ml
We have been adding 1.5tbs of Oxyspa (MPS) after each use as instructed
After a couple of days I retested the pH and found it was above 8 and TA=150. I added multiple doses of spa down and acid magic over multiple days with no change in pH/TA.
Today, I had my TDS checked today, since the pH wasn't budging, and it was 3,000 after 1 week of 2 people using it 1-2 times a day.
What could account for this? There was a fair amount of white chips in the water after starting up the spa. I cleaned the filter 2 times to remove residues. Could it be from left over residue from the previous owner driving up the TDS?
Any advice would help, this is my first spa and I am totally frustrated. So far not as relaxing as I had hoped.
