I received my Bullfrog spa in November. As a previous pool owner, I thought I knew what I was doing. Now I know that I most certainly don't! After adding too much chlorine and shock to my first fill, I ended up draining it and starting over after only 2 months. I had gotten the CYA very high from over use of chlorine and things got really whacky. So I started over about 2-3 weeks ago, fresh fill.
Post fill numbers:
FC 0.11
pH 8.0
TA 99
CYA 5
So I added a pint of spa stain & scale (per Leslie's advice)
2 tbsp pH down
1 tbsp granulated chlorine
So, I was dialed at the beginning of the year. I was intent on NOT over adding chemicals this time!
I've done a good job of not letting the FC go to zero.
I've been adding MPS non-chlorine shock after every usage.
My challenge is I'm seeing the pH drop multiple times (4) in the past few weeks. I've been adding a tbsp of pH up each time to fix the problem. The ONLY chemicals I've been adding is enough chlorine to keep the FC in range (5 tbsp total in few weeks) and a fair amount of MPS @ 7 tsp per bather hour (24 tbsp total in few weeks). I'm surprised that I've had to raise the pH four times (almost twice per week). Is it because I'm over using MPS? Any advice welcome!
