New to BBB method and this is what I have. I uncovered my pool to water that was semi cloudy and I added 12 pounds of shock (sodium dichlor) and put cover back on. I ran pump for 1 week with cover on. Used solid cover. No visible algea when I re-opened pool but water was very cloudy. Considerable scaling in pool walls which I scraped off already while in pool. Used a spakling knife to scrape it off, and it came off fairly easy. Definitely added some calcium to the water making it even more cloudy.
Went to pool store and had water tested. After many gallons of muriatic acid and using aeration ( used my spa blower to raise ph) I am at this point. Here are my numbers as of a few minutes ago.
FC = 1
tc = 3.5
ph = 7.2 (still recovering from acid last night)
ta = 180 ( was 230 at pool store 5 days ago before using acid)
ch = 330
CYA pool store said 30.
Last year the pool center said my cYA was about 100 and it caused me to use tremendous amounts of pucks to get the chlorine levels where they should be. This year I am not using pucks, but have been using 6% bleach that I purchased at Walmart. I am having a problem performing the CYA test. I add water, add solution, mix for 30 seconds, and when I pour it in the tube, it takes a full tube and I can still barely see the black circle. If i read this correctly, then my CYA is over 90, and the pool store gave me a faulty number a few days ago, because I did not shock or use pucks since they tested my CYA.
My pool is still cloudy and I use fiber clear and have backwashed 2 times since the weekend. My chlorine level does seem to be holding overnight, so I believe I have no organics in water, but I don't ever remember it taking more than 2 days to totally clear up water. Any idea where in the heck all the calcium came from that caused scaling? DI I do wrong by adding shock, and then recovering and running pump for 1 week? The water is 6 years old, and we get alot of rain so i add water many times throughout the season. I do realize that for the first 3-4 seasons, I opened the pool, ran the pump for a day or 2 and had crystal clear water. You think I need a water drain or partial drain?
