OK, I have to say I have been a little reluctant to go fully to the BBB Method. However, after reading the site and learning more about the pool chemistry, I have decided to go to that method.
Now, for the statistics. My water is clear. No problem there. My concern is with CYA of 65-70 based on my TF100 kit. We have had some rain and now its finally sunny outside today. My decision today is to vacuum on waste and turn the hose on to replace water while cleaning the pool at the same time.
I stopped using the pucks so that CYA stops being added to the water. 70 is not bad, but its not really good either.
So, I have enough Sodium BiCarbonate or TA and I have enough Soda Ash or Sodium Carbonate PH so I should be fine on that end for the summer I hope. My main concern is what is the difference between Sodium Carbonate and Sodim Tetraborate or Borax? They both increase PH don't they?
Also, I have been using liquid chlorine, but am finding out my pool place is not as good as a deal as I thought or at least I think anyway. Lets here what you guys think. Here is the numbers on that:
They charge me $5.25 a gallon for 12.5% on a 128oz jug at my pool store. Is that a good deal? I plan to run down to Walmart after dinner today to check on the 6% ultra bleach cost. Yea, I know I will need to double the amount added to my pool, but its here in town unlike our pool store thats 100 miles away So I think buying the 6% bleach and just having to add a double dose of it will get me the same results correct?
I have found that adding 22 oz of the 12.5% is about what I need a day so my math should be double then for the 6% to get me those same results and keep my FC at about 3-6 ppm is where I want it with a CYA of 50 is where I should be at when I get done today with it and then retest it with the 50 CYA goal or at least I hope anyway.
I also have an iron/copper issue in the water and I still have to add a metal sequester from the pool place. That part they test for me and have been really great on giving me free readings and then printing those results out for me and even faxing me a copy. I just have been mailing them a pool water sample. Cheaper considering the gas prices now days and that the closest pool place is 100 miles away!
CH is good at 150 ppm considering I have a vinly lined pool. My TA is 90 and PH is at 7.2 which once I replace water will need to be readded again and then retested later today.
Once I get this done today, I will repost my numbers for everyone.
So, give me your comments please. I am curious what others have found to work well with the least time & cost involved.
I sure appreciate it and that test kit I got from Dave is awesome!
