my ongoing problem is white mold /bacteria which, from what I have read, you cannot eliminate and only control. I have an automatic cover which remains closed most of the time. when I joined your forum I became aware of overstabilized chlorine and went from tablets and high cya of 100+ to less than 20 and used liquid chlorine instead of tablets which helped a lot along with daily brushing and frequent vacuuming. I also cleaned my filter and used a product called pink cure to clear the water. all this time I maintained free cl ,ph,cya ,but could never eliminate combined cl. when I opened my pool this spring I could not see the bottom of the shallow end due to the turbidity. I was late opening the pool because I was out of town. I have been slamming the water for almost two weeks using about 12 gal of liquid cl and I can see the bottom of the deep end through the cloud. I have added algaecide and a product from natural chemistry called pool first aid which has helped. yesterday I added the robard product called pink cure which also has helped in the past. I am confident that it will eventually clear but it is a constant battle. It seems my pool is similar to hot tub chemistry problems because it is frequently covered and warm 85to90f during summer months. I brush it daily when in use and slam frequently. any suggestions on control of organic growth would be appreciated. 
my current cya is <20 or not detectable. my free cl is in the 1 to 4 range between slams. the ph is 7.0 to 7.2 right now. normally the pn is 7.2 7.6. my alkalinity is is 70to80, my ca is 500. I have well water which I run through a filter. my combined cl is running 8 to 12. when the water clears the combined cl will drop to 1 to 3 and free will maintain about the same. I have been using the tf100 kit all last year and this year and I just added 2 gal of 10% bleach plus 4lbs of sodium carbonate to raise ph. the additives I use I found on my own and ordered on the internet. it is beginning to clear and I will continue to slam away.
I am using the tf100 test kit and I do not buy from swimming pool stores. I am currently slamming daily and also raising the cya and ph to normal levels. I have raised my alkalinity to 130 ph is 7.3 and holding.
AFTER THREE WEEKS OF SLAMMING ON A DAILY BASIS THE POOL IS FINALLY CLEAR. I USED A TOTAL OF 21 GAL OF LIQUID CHLORINE AND ONE AND HALF QUARTS OF ALGAECIDE 60. I AM CONTINUING TO SLAM AT ABOUT 2 QTS PER DAY UNTIL MY CC IS NEAR ZERO. I AM BRUSHING DAILY AND WILL CONTINUE TO DO SO. THANKS FOR YOUR HELP.
