Thanks so much!! You are always so helpful, and quick to respond! Your expertise is very much appreciated! Do you know of a brand of MPS that is not as acidic? I have been using Leisure Time with 32.18% MPS.

So I have recently switched to the low chlorine Nature2 system in our 240 gal tub. I am adding 1 tbsp of chlorine once a week and MPS after each soak. When I first switched to this system about a month ago, my levels were as follows (using taylor test kit): FC = 0.4 ppm CC = 0.6 ppm pH = 7.8 TA = 80-90 ppm Calcium Hardness = 150 ppm CYA = <30ppm (filled all the way up and dot finally disappeared) I must admit that over the last week or so I have not been checking levels as they seemed to be doing fine for the first two weeks. Anyway, I just re-tested the water and here are the numbers: FC = 3.5 ppm CC = 1 ppm pH = <7 (was way low!! had to add 15 drops of the R-006 just to get it at a reasonable number of ~7) TA = 10 ppm Calcium Hardness = 160 ppm I am not sure how long the pH and TA have been that low (maybe 2 weeks; do you think any damage could have been done?). Also, what could have caused this drop? the MPS? Should I add ph increaser, or TA increaser? Thanks in advance for any suggestions!!

Thanks for the reply!! I do have MPS test strips. When I checked with the strips it did not appear to register any MPS, well it was on the low side. Should the MPS level always register in the ideal range? I usually add 1-2 tbsp (after each use; which is about every other night). To maintain the MPS it seems as though I may have to add it every day. If thats the case I may have to switch to the dichlor-bleach method once i use up all my MPS, as this could get expensive. Thanks again!! Much appreciated

Thanks for all of the suggestions!!

So I just got my Taylor kit in the mail. I ordered online from Amato (thanks for the recommendation; easy transaction and speedy delivery). Anyway, I just got some numbers and just curious if I need to tweak anything. Here they are: FC = 0.4 ppm CC = 0.6 ppm pH = 7.8 TA = 80-90 ppm Calcium Hardness = 150 ppm CYA = <30ppm (filled all the way up and dot finally disappeared) I guess I should state that I am using the Nature2 system, and adding non-chlorine shock (MPS) after each soak and dichlor once a week. I just started with this system so still getting used to it. Any comments/suggestions would be greatly appreciated!!

I've been looking to get a nice robe, preferraby terry cloth, and was wondering if anyone knew where I might find one that doesn't cost too much...Also, does anyone know of a slipper material that would be ideal for getting wet. Something that would dry quick?? Thanks

Thanks Mike! I just ordered the Taylor test kit from the site you linked. Wow, what a deal compared to other online searches...Thanks!!

Thanks Ken! One more thing (maybe the last), i notice that my chlorine levels are high (at least 10 based on test strip; i will order the taylor kit today). Is this a function of the intial shock? and will it go down? if so, how long will it take?

Oh one more thing. Where do I get dichlor and boric acid?

Thanks all for the replies! I have to admit that I am new to this. So what are you all using to measure CYA? Also, it seems that a majority of the people use the dichlor-bleach method. I think I may try the MPS method with occasional chorine at first and see how things go. Also, will my pH go down or do I have to lower it somehow? Thanks again

Thanks so much for the reply!! Thats exactly what I needed.

OK, so I have been driving myself nuts for hours researching Nature 2 on this forum. Wow, there is a ton of useful info, but i think that I am now overwhelmed. So I emptied my hot tub and refilled with fresh water, added some calcium increaser, added ph increaser (as it was low, although it now reads high?? above the range of the test strip), and added alkalinity increaser to get in range (now about 150). Then I inserted the Nature2 cartridge and added 1 tbsp of Spa56 (chlorinating granules; to activate cartridge). Now I am just waiting for the tub to get up to temperature. I am now just curious as to what Nature2 users are doing on a routine basis. The dealers suggested using a tbsp of non-chlorine shock after each use and 1 tbsp of the Spa56 chorinating granules once a week. Is this sufficient? I realize that I won't know for sure until everything is balanced, but just wanted to see what others are doing. Thanks for any tips/suggestions?

I am switching over to the Nature2 system and was wondering about the recommended filter cycle. The dealer recommended two 6 hr filter cycles a day. This seems like overkill to me, any suggestions? comments? Could I get away with two 4 hr cycles? Actually the dealer said the filter cycle should be 12 hrs a day regardless of what sanitizer is being used.

So I posted this a few weeks ago with no response...so i figured I'd try again. Anyway, just curious as to what all is necessary to run a hot tub on granular bromine. Any special filter? or other chemicals? Thanks!

Just curious what all is necessary to run the hot tub with granular bromine. Do you need a special filter? Or can you just add the granular bromine directly into the water as needed (once a day?)? Also, is it true that bromine is harder on the jets? Someone has told me bromine could ruin the jets?? Thanks in advance..
