  1. Hi all, We have 500 gal hot tub and have had it for about a year now. I have yet to be able to get PH and alkalinity into spec at the same time - as a result I have focused on PH. I have yet to find anyone locally who can help with this issue. If Ph is in spec, say about 7.6, my alkalinity will be about 20ppm. If I bring ALK into spec, say 100, my PH is north of 8.6. When I bring my PH back down (PH down/sodium bisulate), ALK goes too low. When I raise ALK, I am using Sodium Hydrogen Carbonate (baking soda) which I have read is supposed to move PH minimally - in my tub, it moves PH up a lot. I have had my ColorQ system verified by a local shop so I know it is not my tester giving me false readings. For example, the sample I brought to them yesterday, had PH at 8.1 with ALK at 47ppm. I followed their recommendation to bring both in spec(ph down and ALK up), I tested this morning and had a PH of 7.7 and ALK of 25. Has anyone had this issue? Ideas? Thank you Rich
  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. Hello, I'm a fairly new hot-tub owner, and have found tons of valuable resources on this forum. Now that I have a slightly complicated question, this was quickly my first-choice to seek guidance My tub is 425 gallons (Alps Spas Q-90), last cleaned and refilled on 1/22/17 (sodium bromide + floater + MPS), consistently tested with a Taylor K-2106 kit, and set to 102F. Problem is my measurements today have me really scratching my head. TA dropped, and my CH plummeted. I've been busy so the tub's only seeing 1 or 2 bather-hours a week lately. Here's the last few measurement entries in my logbook: 2/11/17: pH=7.3, TA=120, CH=100, SI=-0.3, TB=0.5 2/12/17: pH=7.6, TA=130, CH=100, SI=0.1, TB=5 2/16/17: pH=7.6, TA=130, CH=90, SI=0.1, TB=4.5 2/20/17: pH=7.4, TA=90, CH=40, SI=-0.7, TB=5 Should I be worried that CH and TA tanked? I know bromine is acidic, which can lower pH and TA over time, but I've never seen my calcium dive like that. Also, I did add Leisure Time "pH Balance" during this last refill, which says "Note: due to the unique buffering capacity of Leisure Time pH Balance, it is not necessary to adjust the calcium hardness level in your spa". Was that a mistake? Could it be interfering somehow? Thanks in advance!
  4. So I have the public spa that is about 3000 gallons. It has been really cold here (like between -10 and 20*) We keep the window in the spa open to keep the room from fogging up so we lose about 3" of water/day. We refill the water everyday to keep the water level higher to prevent the filter burning out (due to evaporation). My TA for the last 2 weeks has been between 170 and 190. The water that we fill the spa with is city water. After testing it yesterday, i found that the TA of the city water is 170 (according to the taylor chem test). With this number, i would have to add acid everyday to keep the TA within normal range. Is this a big deal and what are some suggestions? the floors and walls of the spa are a type of concrete. I don't want the acid to erode the concrete. thanks!
  5. 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
  6. HI All, I recently replaced my hot tub's heat exchanger and 60 days later it is leaking. The pool guy said it was from the hot tub's alkalinity being too low therefore the part would not be under warranty. How long would the low alkalinity of the hot tub take to damage the heat exchanger? Thank You!!
  7. 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 they should be. We are using Chlorine, and maintaining optimum levels has not been a problem. The PH, however, as well as the Alkalinity, are always high, and don't respond at all to PH-down, Alkalinity-down, any of the Spa Down products. We've emptied, refilled and started from scratch, always with the same result. Tried new filters as well. Though the water is from a well, it is treated extensively by an in-home system, and has been analyzed by our dealer as well as others. A high iron content has been flagged in the water, yet the dealer and others see it as something which should be easily treated. Yet the products are not working to bring down alkalinity or PH. Any ideas or suggestions are very much appreciated.
