I'm nearing round 3 with some sort of staining on my pool surface. 6 months ago I had the pool acid washed and it looked awesome. Now, after working the BBB method, I'm getting incredible staining/scale??? It's spreading like wildfire and is worse than ever.
Here's the history:
March 2014 - Acid washed the pool / refilled pool
April - after a month of running balanced, added borates
July - started to notice a change in the plaster
Aug - plaster started looking real bad. I did a vitamin C test, and it didn't quickly work. I picked up a Jack's Stain ID kit, and the copper & scale packet worked immediately. No other test in the kit produced better results. So I started down the copper route - I also have always had brown staining in the pipes. I requested the most recent water analysis from the city and copper was just over 1.5ppm and failed. I concluded copper was my culprit, and added 2 bottles of Jack's Magic Purple. Also, based on recommendations from this forum, I reduced my pH to 7.2-7.5.
Sep - the Calcium test jumped from 275 (which was consistent for months) to 400!. My fill water is <200. Also, while I was out of town for a short period my TC jumped to 9.0. It's now down to 4.0 (see below).
Today: it is worse than ever and another acid wash is really not possible here due to water restrictions. Here are the current water test results:
FC/TC = 4.0

Any thoughts/suggestions? Since Jack's Copper & Scale remover worked, I'm considering going that route, which will require some plumbing changes to bypass the heater. While that's fine and may work, I'd like to prevent it from coming back.
Is there any chance that the Borates affected/exasperated the prior issues? Also, would a sequestering agent cause an increase in CA reading? I have been continuing to add Jack's weekly - could that be accelerating it?
Thanks in advance
