  1. I've drained and filled my hot tub twice. Both times it needed about 12 sodium bisulfate to bring down the Alk & PH. When I do a drain and fill, can I add that entire amount (12 OZ) at one time? Any tips? THanks, Doug
  2. I have a 400 g. hot tub and measure FC and CC with a Taylor k-2006 kit with MPS correction regent R-0867 AND a Hach strip. Both Taylor k-2006 kit with MPS correction regent and Hach strip show increases in CC from 2.0 PPM to 4.6 AND FC from 1 to 1.8 in the past few days but I have NOT added dichlor, chlorine or bleach. I've only added PH down, Alkalinity UP and MPS. Should any of these INCREASE the FC and CC? I use Nature2, MPS after every soak (daily) and weekly addition of 1 cup bleach (my CYA is 100). I used to use 2.4 T. diclor weekly. Thanks, Doug
  3. I used the K-2006 with MPS regent to get the CC readings so I'm guessing they are right. Confirmed 5.0 with two brands of test strips too
  4. I have a 400 g. hot tub with Nature2, MPS and occasional adds of bleach because CYA is high (100 ppm). My combined chlorine is 5.0 in my hot tub. Free chlorine is a 2.0. Can I fix the combined chlorine with MPS? If so, how much should I use? Any other recommendations. Thanks! Doug
  5. Thanks for this very helpful post. Why is it recommended to have any CYA in a hot tub if it reduces effectiveness of chlorine? What is the best level of CYA to maintain in a hot tub. I've seen 20 or 30? I use Spa Choice Diclor which the ingredients say is 55.5% available chorine. How much of this diclor would I need to add to my tub to get it to 30 PPM? Thank you very much! Doug
  6. I have a friend who has had hot tubs for over 15 years that is trying to get me to switch over to saltwater. He runs a saltwater spa and said its so easy and very effective. Are they an effective sanitizer? Do they damage pumps or spas? Any thoughts or suggestions? Thank you, Doug
  7. I've done LOTS of reading on this site and learned a TON. I've been using Nature2 with MPS after soaks and ensuring MPS level is OK with Nature2 strips before soaks. I currently use diclor shock about once a week. I like this system but want to ensure I keep my free clorine at 0.5 or 1.0 because several folks have suggested that. What is the best and easiest way to do that? I prefer to do this without switching diclor for MPS after soaks. I use tub daily or more and leaving cover off after diclor is a pain in the winter because I live in MN. Thanks, Doug
  8. Waterbear....thank you very much for your details above. VERY helpful. When you say, " test sanitizer weekly using FAS-DPD (Taylor K02006)," what is the sanitizer???? Do you mean chlorine or bromine or mPs or whatever you use OR do you mean something else? Thanks, Doug
  9. If you used strips in addition to the Taylor kit for frequent testing, what test strips do you like the best? We used our hot tub daily or more. With the strips you're recommending, are there tests on the strip that are especially inaccurate and you should always use th Taylor kit
  10. Hello. I run Nature2 with non-chlorine shock and occasional diclor (weekly or a bit more often). One of the staff at the Nature2 company said......……if free chlorine readings do not match "not free Chlorine readings", I should shock with diclor. I think that's what he said but I'm curious if he was saying free and total chlorine reading should be the same. How do I measure "non free chorine" readings. Do I just subtract Total from Free Choline to get "non free chlorine" Is this important to be checking and how often would you recommend checking this? Any other informatio
  11. What are the advantages of using diclor versus MPS? If using diclor instead of MPS, do you need to monitor for CYA? Do you need to monitor for CYA with MPS? What do you do if CYA is too high or too low? (I don't understand CYA yet.)
  12. Curious what test strips, liquid tests, kits, etc. do you think are a good balance between accuracy and price for..... clorine Alk PH cya Calcium MPS and anything else I should be testing in my fresh water spa with Nature2 purification with MPS. Thank you, Doug
  13. Is the flow in the inline system as good as it would be with the stick in the filter? The guy at my Marquis store said it is not but that does not make sense to me. --Doug
  14. I have a 2005 Marquis Silver Anniversary Edition hot tub that's about 400 gallons. It has the inline system that can be used with the frog products. This spa has two filters and they are not open on the top. The inside diameter and design of the filter makes it really hard to install in the filter. Would it be as effective to put the Nature2 stick in the inline spa system? Would it get enough flow to work as well as being in one of the two filter? Any other thoughts or ideas to mount it in the filter would be appreciated too. Thanks, Doug
  15. I'm putting a 240V hot tub on an existing concrete slab about 5 ft from my garage. Can you run electrical run in conduit on top of the concrete OR is this not typically allowed for code? If not, any other ideas so I don't need to rip up a good concrete slab? Thanks, Doug
