  1. I am trying to do the decontamination process from Nitro. I have already done the enzyme part and dumped that. Now it's filled and I am trying to balance it to the TA of 80 and PH of 7.2. I've got the TA at 80 but nothing is getting the PH down. I just bought the test kit K-2106. The PH is showing at the highest level, and I only have to add 2 drops and it turns pink. So I check the book and for my 350 gallon spa I calculate that I need .63875 oz of muratic acid (18.89 ml) I do that and come back a few hours later or the next morning and test again. It gives me the same thing - high
  2. Hi there I have been struggling with high ph but good alkalinity levels. Alkalinity is in perfect range as is the hardness and sanitizer ( use bromine) but ph is consistently high. I lower it with ph minus and it comes down to normal but then within a day it is high again. Any recommendations on how to deal with this?
  3. Hi My water is very low Alkalinity (40-50) and high pH (~7.9 or 8). I can not seem to get the TA up to 80 and the pH down to 7.6. I am using baking soda (sodium bicarb) to increase alkalinity and Spa Down (sodium bisulphate) to bring pH down. bringing pH down brings TA down, bringing TA up brings pH up. Appreciate help and suggestions. If there is an existing thread on this topic, please point me to the comments and wisdom. thanks
  4. Hotsprings instructs users to put all chemicals only into the filter compartment. We are using bromine granules, and coincidentally?? the only time my water remained clear is after I put the bromine in the main tub area rather than filer area. Is this a coincidence? Background I have a new hotsprings Pulse spa and the water was cloudy after several days. I discovered the installer put the ozonator check valve in backwards. After many attempts with dealer to fix the chemistry, we finally drained and refilled tub, Then followed all instructions and water became cloudy after a few days
  5. Hi, I've been wondering, does increasing pH with NaOH also increase TA? Thank you [Edit] Already found my answer in pool calculator. Yes it does raise the TA.
  6. Hi, First off let me give you the specs and current water parameters. Clearwater 475 gal. With ozone & uv. 98° Typical user load is 4-5 days per week, 2 people, 1 hr. This is the first water fill and it has been running for approximately 3 months. Using Taylor K-2006 test kit Currently using a mineral stick in filter 1. I've been using 6% liquid bleach since my cya hit approx 35ppm. Ph6.8 CH 180 TA 60 FC 6 TC 1 I have had my TA @ 120+ for a while and have constantly Fought with pH rising to and above 8.0. Finally decided t
  7. For the past 3 days I have been trying to balance the pH and TA in my new Intex PureSpa. I have the impression that these need to be balanced before adding any other chemicals. I have done 24 tests in 3 days, and have made 23 adjustments, using only pH Down and Alkalinity Increaser. I am using up a lot of test solutions (in the Taylor test kit) and a lot of chemicals. I have added the pH Down and the Alkalinity Increaser separately, always running the cartridge filter pump and the jets. The jets shut off after 30 minutes, and at some point after that, I retest. I am pretty sure that I ne
  8. Hi Guys Just thinking out aloud here I've been reading that aerating will naturally increase the pH of the water. Obviously, pH+ increaser will do have the same effect. Does using pH+ have any side effects? Thanks
  9. Ok so we got the Intex 77-Inche PureSpa on Prime Day to help with my Mom's bad back but were having some trouble getting the PH and alkaline just right. The Spa is 210 gallons and filled with water from our community well in southwest VA (AKA alot of limestone). The PH and TA both max out the test strip and I'm finding conflicting information online. So far I have added 202 grams of Clorox PH down as per the manual to bring it down 100 ppm. The strip in now reading somewhere between 180 and 120 for the TA 30 minutes later but the PH is still around 8.4. I haven't added any chlorine yet becaus
  10. I have been struggling with this problem for awhile. All my reading this subject hasn't helped. 360 gallon hot tub. My TA drops so I tried to raise it. I'm using SpaGuard Spa Total Alkalinity. Every time I attempt to raise the TA, my pH spikes. Then I'm following up with several cycles of pH decreaser. A cycle being putting a small amount of pH decreaser in, running jets for 20 minutes then checking. Because my TA has increased, the pH is slow to come down. The basic question is, why does my pH spike when I increase TA? Thanks, Scott
  11. So I have had my spa for a couple months now. I thought i had things going pretty well with my water but now I have the issue that my TA is at 120ppm, but PH is showing 6.8. If i use the spa up to get my PH in line will it not then raise TA to above what is recommended? (120ppm) We use the hot tub almost ever day and I have been using shock and chlorine after every soak. I'm considering just using more chlorine after each soak instead of it and shock, after being told that using that much shock could show up as CC when testing. Would the use of shock also effect PH but not TA? or the us
  12. Hi all: I am fairly new to the hot tub I have (I bought the house with the tub already here). It is a 500 gallon, and I use Chlorine. The first time I started up the tub, I struggled with PH and Alkalinity. The second time, I used "Leisure Time pH Balance Plus" when I first filled it. for my 500 gallon tub, I used a full 3lb bottle per the instructions. For that fill, I had perfect PH and Alkalinity for the entire time until I drained it. Now I am trying to recreate it without the $20-$30 expense. The MSDS says that there are only 2 ingredients, baking soda and boric acid. Does anyone know
  13. How do I bring the total alkalinity up, without raising the ph? When I first fill my hot tub the ph is perfect (7.6) but the total alkalinity is somewhere between 20 and 30 (should be between 80-120)? I use alkalinity increaser, then my ph goes thru the roof. When I decrease the ph, down goes the alkalinity. I constantly have this yo-yo effect. Any suggestions?
  14. I have been told different things in regards to the pH of the water when closing the pool. What is the ideal pH as we close? Actually we need to know all the chemistries, including the calcium level, alkalinity, and chlorine. Also, our pool builder told us we don't have to put antifreeze in the lines here in upstate new York. Isn't this a risk? Thanks.
  15. About a month ago my wife and I purchased a new Jacuzzi J-345. In the past month I have had a crash course in spa water chemistry. It was a little overwhelming at first, but I have learned a great deal, thanks in no small part to this forum, especially Nitro's post. The spa is equipped with the ClearRay UV sanitation system and came with a “starter kit” consisting of a bottle of Silk Balance, pH increaser and decreaser, chlorine powder (dichlor), non-chlorine shock (MPS), and some 4-in-one test strips. According to the Silk Balance brochure, all I had to do after filling the spa was add a ta
  16. Hi. Just joined today, and although I've done my homework on water treatment, I hope it's not unheard of that things don't always play out according to plan. Anyway, my Spa is a 2012 Dimension 1 Arourora. I have had it now for about 3 months. It is situated in a screened in porch enclosed on three sides by the house, and one side by screen. The home where it is located is a weekend home (Hudson Valley, NYS), and which makes it a bit more difficult to stay on top of the water issues. So far, we've had no major water problems such as cloudy water, foam, smell, etc…, but our readings are not what
  17. Hello all. Thanks for all the fantastic info on this forum. I've learned so much. I just bought my first spa, 500 gal Artesian Island and love it. Had it for 2 weeks and am researching chemistry and sanitation like a mad man to the point of obsession. The spa has an ozonater and the dealer set me up with an initial Spa Frog system. I've got 1 unused bromine cartridge and once it is done I'm dumping the Frog for bromine tabs in a floater (I've researche the 3 partbromine set up system). We have heavy use with teenage kids and friends and the low level of bromine was not keeping up with the bio
  18. Hi, Been reading the forum a bit more now. The following question rose to my mind. Wouldn't testing these 4 parameters suffice (for my pool). My pool being plastic above ground, outdoors and no splashing, pH elevating fountains or such. CYA: test CYA to reach optimum level. pH: test the pH and correct pH with hydrochloric acid or sodium bicarbonate when necessary. FC: test FC and correct with bleach. TA: test and correct with sodium bicarbonate. The amounts of HCl, NaCO3, trichlor and bleach needed will be calculated with pool calculator. 'Correct' me if i'm wrong, Tim
  19. Hi all, New to this forum. First post. I installed a 6000 gallon pool in my garden a few weeks ago. So im new to the world of pools also. Have been reading a lot of forums on pool chemistry. I think i understand the pool chemistry now. So i will tell a story and please correct me when im wrong, or feel free to add things if i left them out. So... Istalled 6000 gallon above-ground pool couple of weeks ago. Filled with tap water. Bought shock (unknown white powder ) from local pool guy and added to pool. Adding 2 tabs of stabilised chlorine and replacing when dissolved (about once a week).
  20. Question 1 # Why won't my PH settle into the 7.2-7.6 range? Question 2# Why does a light film build up at the water level? Question 3# Are the above questions the reallity of owning an acrilic tub, the Muni Water or bad readings? North Texas Municipal Water stats Treated mg/L TA = 100 Tot Hardness 152 Non-carbonite hardness 51.8 PH 7.84 Chlorine Residual 2.94 I have had my 380 gallon J-335, with Proclear inline mineral cartridge for three weeks. I find that my consumption of test strips, PH decreaser and wiping the shell at the water level is more than I expected. My water is clean
