Yes, I have a stenner tank and pump for the acid. The CAT controller and the manual pH test show 7.5. The acid consumption has been very level and steady. I'm not sure what your thinking or what you want me to check. My chemistry has been really quite good in every category. I have been...

First off, I have been trying all weekend to post pictures. It seems like it should be so easy. But not for me!! Is there a file size limit? It says downloading and spins forever. I tried all the pictures one at a time, without success. Help! I have been somewhat hesitant to report the...

You are correct, I was new to this site and somehow missed the complete line-up of stickies. I was reading the postings and trying to piece everything together. Once I got the how-to figured out, it worked great and I have no regrets. I have given this site and BBB technique to countless...

Hey Casey, Thanks for your interest. Still trying to get the whole chemistry experiment dialed in.... Things are better but not yet perfect. I will try and get some pictures posted ASAP. Jeff

Ran the test last night at approx 48 hour mark. Still a trace of CC. Still a cough with initial spa start up. Definately better than it has been, but still there. I am not going to get excited either way until the CC is zero. Hoping tonight will be it. Thanks for the support. Is this PSI...

Oh, the sanitrol system I have is a bit undersized. My pump puts out 120-160 gpm. Currently I handle about 80 gpm. They sent me a different UV bulb, I think he said 185nm. I didn't remember to ask why? Undersized system?? The bulb for pools applications?? Or something else??

Brief reply from my phone. I installed 2 sanitron tubes in parallel. It handles about 80 gpm. My CC went from 1 to 0.5 in 24 hours. The only other test change was an increase in Alk from 100-110 to 130? We did run the spa..... Initially the water acted like it was carbonated (little tiny...

I actually don't know if it is low or medium pressure. I guess I didn't know there was a difference despite all the research. The company is ultraviolet.com. Their web site includes swimming pool applications and of course they say they have very good success with issues like mine. I will keep...

Richard, thanks once again. I was within a day or two of posting a message. I bit the bullet and bought a UV light system. It arrived on Friday and I spent all day Sunday piping it in. I ran a baseline set of numbers. So we will see what happens. At this point a lot of prayers :). The UV...

I am sure that my "playing" Junior Chemist took care of all other options except for high dose MPS and the UV. I tried high dose Chlorine and super dose chlorine (accidentally). Also, I did add 9 pounds of MPS to "shock" the pool when initially we thought that this might help the problem...

First of all, thank you for your help and concern. This forum is evidence that there really are some good people left in this world. Second, how many types of chloramines are there? Is there a test to differentiate the chloramines types? We spent a ridiculous amount of time and money...

I was re-reading the posts within my topic. I found Water Bear's comment "Persistent chloramines in indoor pools is a known problem partially because they do not get exposure to the UV light that outdoor pools do. UV is needed to effectively break down chloramine when shocking. This is why...

OK - I am beyond frustrated....and ultimately deflated. I have run the "experiment" countless times in the spa without "complete" success. I have altered the variables up and down. Higher CYA, higher and lower FC, more ammonia, etc. I no longer consider myself a junior chemist wanna-be. At...

Pool has been covered since last weekend (like eight straight days)...I think. Since I was away, I don't believe my wife went swimming. What is the down side to treating the whole pool with ammonia? My high school and college chem has completely left me. I think the CC needs to be dealt...

Finally home. I hate winter travel!!! The pool is crystal clear and looks fantastic. I tested the pool and was a bit surprised: pH 7.4 (CAT controller 7.7), FC barely 0.5, TC 1, Alk 100, OPR 650 (would have thought this would be lower and triggering the bleach pump). Ran the spa...

I did mean salt (not TDS). I added a bit of salt for the silky, smooth feel. May eventually go all the way to a salt system, but elected to wait. Wanted to see if there was any corrosion before investing in the commercial generator for my size pool (big $$$). Will run a full fresh set of...

Sorry for the delay. I have been out of town. Should be home on Sunday night and will resume the testing. Happy Holidays to you.

Don't leave me yet... I still believe :wink: However, I have closed down the witches caldron for the night. The FC is/was holding in the end. It did drop initially and during the middle but when I over shot the FC at the end there was essentially no drop after the last ammonia dose. I only...

Well..... Still adding ammonia and still coughing. I have added beach twice to keep the FC up. Got a bit aggressive last go around. Have the FC at 6. Have added a total of 8 teaspoons (4 doses of 2 teaspoons) of ammonia. The last test, I diluted the FC sample down (per Taylor's...

Test re-do is done. Pre-test: FC was raised to 4. TC 5. pH 7.6 2 teaspoons of the 2.5% ammonia added. Wait approx 2 hours. Results: FC 1. TC 2. pH 7.6. COUGH STILL PRESENT!! :grrrr: I'm still have the spa isolated, I'm going to add the additional 1.5 teaspoons and see what happens.

The spa test is done. But the whole reason for this exercise (the smell) wasn't tested. I was trying to direct my wife over the phone, when I got the results I told her to take it out of spa mode. By the time I thought about it, it was too late. Plan to re-run the test in the AM. Anyway...

For the sake of speed, I will use the 2.5 percent ammonia that I already have. I re-did the math, is it correct that I only need 3.6 teaspoons to treat the entire spa? I will treat and report back in a few hours (with fingers crossed). Thanks again.

I am away from home and having some trouble estimating the spa volume. As I recall, the spa is approximately 5 x 7 feet. Maybe 3 feet deep (standard depth?). There is simple bench around the entire perimeter of the spa. There are also two small steps, one above the bench and one below coming...

When the pool was built it included a "puck" chlorinator, in addition they added a load of CYA during the initial start-up. I forget how high the CYA (somewhere around 100) was when I figured out they had screwed up. I have since removed the chlorinator, drained half the pool and refilled it...

My wife spent about 10 hour venting and aerating yesterday. When I got home and collected the chemicals I began the bucketing. Bucket test done! Here is what I did, please check my procedure and math. Pre-bucket pool readings: pH 7.6, FC 0.5-1, TC 2, CC 1-ish, TA 110, CYA ? lost black dot...

Almost forgot, is artificial UV lighting an option?

WOW!!! Seems like chemistry homework from 25 years ago. I will get to work tomooriw night and post the results. A million thanks in advance. As fas as the ventilation, we think we have a very good system. The problem is not swimming for a few days and the auto cover is in place preventing off...

Richard thanks. I'm typing this on my phone, so the reply will be short. Pool open for a year. This coughing problem had been a problem almost the whole time. Excessive splashing and especially the spa jets make the coughing horrible. Bather load quite low. 2-6 people a few times a few...

Have added several doses of Oxy-brite. Still have the issue of coughing with the pool. Still have the elevated CC. Latest readings: pH 7.5. TC 5. FC 3. CC 2. ALK 110. ORP 770 (went up from 630 after oxy-brite). Borax 50. Salt 1600. Question is: should I shock with bleach to get rid...

Thanks!! I had a bucket of oxy-brite from the pool builder and just put the last of it in the pool. I looked online to purchase more, it appears there are several brand names: Blitz, Impact, Shocktrine, Oxy-brite. Are they all the same??? I never know when when you buy generic cough...
