Thanks Scott, I talked to my wife and she said the pool looks a little better today. I really can't wait to get home and get this thing cleared up. Maybe it will be ok by the time I get home. One could only hope. I am not sure if I should have her shock it tonight without knowing the levels, or just up a gallon of bleach in and hope the filter takes care of the cloudiness. Any thoughts on just blindly shocking if I don't need it?

Without testing, could I have killed all algae/bacteria? The pool is cloudy but no chlorine odor. No ammonia levels were present this am or a reading of 0.25 ppm. Maybe time away with filter running can clear the fine dead algae. Any thought are welcome. Before reading this forums I added copper sulfate to kill algae and added algaecide 40 to prevent any new bloom to occur. I am hopeful that my filter just needs to do its job.

Well I shocked the $*** out of the pool starting yesterday morning. I used dichlorvos first couple of times to raise the cya and shock at the same time. I know I lost some ph along with that. As soon as the sun went down I started the 6 gallons of bleach per dose to get me to 10 ppm as suggested by the calculator, I got 4 shocks in last night until I went to bed at 2. Woke up this am and had a FC reading of 3/4. Soi shocked again. This time I adjusted to amount just to reach 10. I checked back 6 hours later during the day and still had some FC. shocked again. I tried to adjust the ph a little bit ago by adding borax to get the number up. I am planning to reshock at 10:00 then again tomorrow am. I leave for Boston tomorrow and I am trying to figure out how to have my wife add bleach while I am away. Maybe just one shock at the evening, and maybe cal-hypo tabs in skimmer during the day. Any suggestions. She won't do the tests. And I ran out of reagent for the FC I am using guess strips. Oh well fed ex needs to get me my new test kit by Thursday when I return.

Waterbear, I purchased an ammonia test like you said and the result was between 5-8 ppm. Ughhhh! Just went and 18 1.5 gallons of bleach. And I have 50# of dichlor. Can someone advise me on how much to put in?

Waterbear, Are the amounts I added wrong or not enough based on the tc of 10 and fc of 0 I originally measured?

Just added 5# of dichlor. Try to get 15 ppm level. My thought is that it would add some cya to the pool also and I had 50# already bought due to the advice of the Pool shop recommendation. I will try to keep it at FC of 15 as per waterbear recommendation and see what I get. Pool is cloudy still. But not green. Not improving either. Pump has been running 24 hours a day since Sunday.

If I add three gallons of bleach tha would give me a 6 ppm, correct? Then repeat tomorrow?

Thanks waterbear, Got it, algaecide 60 for closing from now on. Any suggestions on the chlorine shock load I should add tonight when I get home?

I Did all that pool.looks blue but cloudy and the resulting test report is what I am left with. I put some copper sulfate in the pool skimmer to kill whatever algae is in there. Now if I could get a free cl level without adding 40 gallons of bleach I would be happy. Any help on the cl would be appreciated. I did buy an ammoia test but I am not home yet to test it. I told my wife not to add anything until I get home. Hopefully with some advice from this forum on quantity of liquid shock.

Does the algaecide 60 work better than copper sulfate crystals? I will definitely use that next year for closing. Should I add that now to make sue everything is dead before adding the cl or is the algaecide40 I added this opening, combined with three tablespoons of copper sulfate enought to kill what's left after the initial kill off with the 9 gallons of bleach?

I live in Pa, so I usually close the pool in October, open up in May, i have a Merlin pool cover that lets the water through. I make sure all chems are balanced before closing, shock it with the suggested amount for winter, i add a gallon of algaecide 40 and close it up. I had a giant algae issue when I opened it on Sunday. I opened 4 other pools and 3 of them were as dark green as mine. Mine seems to be the only ony not responding to the initial shock treatment. I adjust frustrated the my neighbor' s pool I opened and closed with the same proces was perfect when I opened it. When the pool place told me I was crazy to use bleach and that stabilizer wasn't an acid, I realized that their suggestion of adding 50# of dichlor was one I was not going to follow. I was reading about soil bacteria eating the cya and I don't knows if at is possible in my situation(I don't have any run off into my pool it is elevated from the surrounding area.) could e large amount of algae initially cause the same problem? I have dealt with pools for 25 years and never had as many issues as I have in the past three years with this large of an inground pool.20x48. Thanks for your help.

Tc 10 FC 0 Ph 7.5 Cya 0 TA 120 Copper 0.5 Iron 0 Phosphates. 0 That is all I can remember I am on the road.

This no cya and cl demand seems to be common for me when opening the pool. What could I do to prevent this problem?

Waterbear, Thank you for the reply, I have been taking your advice for a while now. My pool is 35,000 gallons, it is a vinyl lined pool with a sand filter. My original understand of the TC v FC was I needed 7x the amount of cl in ppm to get a reading. That would be 70 ppm. So I figured to let the sun burn all the cl out and try to restart the CL process. The pool is cloudy and have been vacuumed by me manually and the robot for the last couple times has been coming up clean. I appreciate your expertise and advise. John
