I have not had this problem before. Refilled the spa yesterday and initial TA 230. I did the acid/aerate routine a few times and I think I was over-zealous with this. Since my pH was getting less variable, I checked the TA again, and when I was putting the 5 drops of R-0008 in the tube, the...

Hello, I used to have a pool, loved TFP and learned so many things. We are now getting a hot tub and I am trying to find my way to pool school on this site for hot tubs and not sure what I am doing wrong but can't seem to get there. It looks like there is a section on pool and hot tub...

Here are my numbers this am. FC 5, CC 0, pH 7.2, TA 80, CYA 20. I want to close today if I can, it has been a whirlwind fall with very little time to spare for me. I haven't added bleach for over a week and I am still at 5. (I keep solar cover on it all the time.). My questions are...

First off-welcome! This site has been a godsend for me with caring for and maintaining my pool. I have learned so much and so far I am three years with a sparkly pool. Second-read pool school and then read it again. Learn to understand the CYA to chlorine ratios, find PoolMath to help you...

I am about 85% certain that I have no need to do anything but just want to check to make sure. I checked everything today with my test kit and my CH is 110. Since I have vinyl, I have no worries in that respect I think. But, I just would like to hear that from someone with experience. What...

Last year was my first winter closing. I used a solid cover and the wind blew it up like Jiffy Pop popcorn all winter. I bought some pool clips and they blew off, then I purchased pool wrap thinking that would help keep the wind from getting under the cover and it did not help either. We are...

Does anyone have a preference for a manual vacuum head style or brand? I have an automatic pool cleaner but it always misses spots so I am going to get a manual head to get those areas. I see triangle shaped ones, rectangle shapes, some with wheels, some with brushes, some without. I am...

I bought new testing supplies for this year but I am wondering if the DPD powder from last summer is still good. Hoping to not need to SLAM my pool this summer but just in case I need to, I thought it would be nice to have the extra powder around to use if I ran out of the new stuff. What about...

I purchased a mechanical timer that can have up to 12 on/off cycles. I read in pool school that even 4 hours daily can be enough but I am a clean freak and I can't stand stuff floating on top of my pool. Last year we ran the pump 24/7 because that's what all our neighbors do and that's what...

Is it normal for some CYA to degrade over winter? Is there any reason to want your CYA to be at the top end of your range when you close your pool? I am asking because right now, my CYA is a little under 30 (had to drain some water a few times because of excessive rain). I am not having...

I have been slowly lowering my TA but it is still high ~200. Right now I am adding MA about every 3-4 days to drop pH to 7.2 and letting it creep up. I am going on vacation in a few weeks and have someone arranged to check the water and add bleach daily but I don't want to ask that person to...

Thursday is my "test everything day" and here are today's results: FC 4.5 (going to add chlorine to goal still tonight) pH 7.5 (going to drop this down to 7.2 again) CC 0 TA 200 (I am slowly getting this down, using what I feel like is a ton of muriatic acid and pH keeps climbing back up in a...

I have a new pool, new water, new everything and I was lucky enough to find this site before I ever went into the pool store. The question of the day is about borates. I was going to add borates, read the article (that I cannot find this am) on here titled "so you want to add borates...". I...

My TA is somewhere between 280 and 300 depending on my current definition of color change. My pH is 7.8-8 depending on my current definition of color change.... I am definitely not interested in burning eyes, so with my inexperience with pH testing I am a bit leery of trying to drop to 7.2 and...

I understand that it takes about a week for added CYA to be measurable with the test kit. What I am wondering is how long does it take for it to work as an effective stabilizer? This is my first week/first pool and I'm just trying to understand the chemical balance and get a feel for how much...

So, working on the 4 days of dichlor to get cya level up. The dichlor came with the pool so I decided to use it instead of buying CYA by itself. I noticed after 2 days that the chlorine level stayed pretty high ie>8-10 throughout the day (am testing am and pm so far) so in order for my kid to...

So I purchased a "pool kit" on line and I have had problem after problem. I'm not in the habit of online bashing so I will not go further with company details. My latest problem is this: I have a 24 foot round pool with no chemicals in it. It took me over 2 days to fill the pool and last...
