JohnT-We live in central Indiana where, yes, it does get below 45 degrees air-wise. However, I made an assumption that the pool water did not get much below 45 (this is a guess due to ground warming the sides of the pool). I have a small (100 gallon) pond as well as the pool, and at most it only...

That's my question. I have a gunnite pool and need to know pool parameters that are best for closing. We cover the pool with the old-fashioned tarp method (not porous) and our water temperatures get as low as 45 degrees farenheit in the winter. Currently, I have: pH of 7.5 TA of 90 CH of 280 Cya...

The calculator page stayed intact until I tried to reset the goal CSI to zero. Then, it disappeard every time.

iflyjetsss: Thanks. I forgot to mention that pH dropped to 7.5, but TA remained at 190. My chorine is fine. That's why I think it will be ok to deal w/TA after the weekend.

My pool is full. The FC and CC are at 4 after I added 7 cups liquid chlorine about 4 hours ago. The pool is clear and I don't want to shock as we are having swimmers tomorrow. Hope it's ok that my TA is 190. I'm thinking of waiting to alter TA until after the weekend. The Ca Hardness will have...

Thanks so much again to everyone who commented. After draining my 25,000gal plaster pool of about 60%+ of its water, my Taylor-2006 test kit results are as follows: FC .3 CC .3 pH 7.9 TA 190 CYA about 20 Ca Hardness 130 (tested by Leslie's because I discovered that my original Ca hardness...

Thanks much in answer to all my questions. I'm still wondering what an appropriate level of calcium level I should establish after I refill my pool. Our local water source is 50-54ppm as it leaves the plant. 350 ppm was my goal, but with summer evaporation at 500gal/week, I wonder if I should...

Do you recommend using clarifiers weekly as the pool stores do? Thanks, CAK57

Re: metal sequestrants weekly/biweekly I have water with no copper or iron in it and yet the pool store says to add a weekly sequestrant. Should I? Thanks, CAK57

Re: Algacide usage Per TFP pool opening guidelines, I see that high quality algacide is recommended after all othe water parameters balanced. What brand do you recommend? Also, do you recommended adding an algacide weekly? Thanks, CAK57

Re: Pool opening I have read that calcium harness should be established first before adjusting any other water parameters upon pool opening. True? (even before shocking?) Thanks, CAK57

Re: metal sequestrant I am doing a drain of about 60% of my water & anticipate zero chlorine after. Should I add a metal sequestrant before I add chlorine? If so, what brand would you recommend? Thanks, CAK57

I live in IN and would like to maintain my calcium harness at 350 during the summer.In our heat, I have to add 500 gals water/week due to evaporation. Our water has 60-120 ppm of Calcium hardness (on the soft side). I am currently in the process of draining about 60% of water from our 25,000...
