Thanks for the response Richard - I will use your method. Thanks for helping me out!

Thanks Richard, you made a correct assumption on the CYA level - I acutally didn't start adding much chlorine until recently so for the first two months chlorine was added only in minimal quantities. So thats why the number I quoted sounds low to you. I would like to save some money - the nature 2 cartidge is 30 bucks so for a 4 month cartridge thats not very expensive. The shock on the other hand does get expensive over the long run when using it twice per week. I purchased a bulk supply of di-chlor off of some guy on craigs list so have at least a two year supply!! So maybe I should use more chlorine and less MPS? My hot tub is used sloely by me and very rarely maybe once per month do I have a guest in it. I do however go in the tub at least 5-6 times a week for 30-45 minutes at a time. Do you think at this frequency I could add MPS just once per week? using bleach sounds scary - how much do you add and at what frequency? Is it the same bleach you use for clothes? Also at what ppm of cya does it begin to slow down the chlorine effectiveness?

Hi Richard, Do you mind giving me an opinion on a maintenance plan for my tub. This is what I do currently. I have Ozone and Silver 1) I add 3 OZ leisure time renew (MPS) twice per week 2)I add about 1oz of dichlor (62% available Cl) 2 times per week I have measure my CYA rencently and it is at 60 PPM according to my taylor kit (my water is about 3 months old) Please give me your suggestion as to what change I should make to my current procedure. Do you see anything completely wrong with my setup? Thanks for your help

Hi all, I was reading about the nature 2 cartidge and seems that they advertise if you use MPS with this nature cartridge then you don't need any chlorine? Is this true, and exactly how much MPS do you add on a weekly/daily basis? What about combination of CL and MPS? Please let me know what any of you are doing in this regard.

I have found the same thing. I need to add chlorine on a regular basis to keep the water nice even with ozone and a mineral cartridge. At $200 you could use about ten Nature2 or Frog cartridges. Although D1 people will tell you theirs holds more silver and lasts longer, I don't see the value. There is no need to use mineral cartridges if you wish. After using both minerals and ozone for four years, I have stopped using both with excellent results. Ozone and minerals help, but I do just fine without them. So Can I use the Nature Catridge in my d1 spa over the vision cartridge? It does the smae thing for cheaper right?

Hi All, This is a great thread and I was about to post almost the same question. I have recently purchased the d1 diplomat. Our dealer basically said you need almost no chlrine in the tub. However from reading various things it seems like that is not necessarily the best advice. Maany are saying you should have chlorine even in a Ozone/silver system. Per my dealer these were my exact instructions. 1) shock with MPS twice per week 2) Superchorinate with 2OZ dichlor once per week 3) clean filter with filter cleaner once per month. After doing this for a bit I find that once per weel of cholination is not enough. Water gets cloudy and smells funny. So now I started adding some 2-3 times per week and it is working better. Here is another question - the D1 cartidge costs 200 bucks (ouch) Can I use Nature in the D1 since it is cheaper to buy? Do I even need to bother with a cartridge if I up the chlorine?

does this matter - I shocked with MPS last night and then superchlorinated. Do these things need to be done at separate times?

Ok was in the tub lat night - though the water felt a little greasy or slimy on my skin. PH and TA is good and I had just superchlorinated a few days prior. There is no smeall or anything else it just feel a bit slimy.

Just got a taylor test kit and measured the CYA - it came out as 60-70 ppm. The book that came with the test said 30-50 was ideal. Whats happens if CYA get high? what is too much?

Thanks for the responses - I as just hesitant to add the foam stuff since I thought adding more chems to the spa would caus eother issues. Have you had any consequences when adding the anti-foam. Does it mess with your water chemistry? I live out in AZ so my water is acutally very hard and ph usually moves up very fast. I will pick up that foam stuff and give it a try!

Having a foam issue - any ideas how to fix this without draining my tub? PH and ALk are ok so I am not sure what elase to look at.

Hey I have your same problem. I seem to always be adding acid since my area had very hard water witha high PH. The other day I added around 5 OZ of acid to get it down to 7.4 - but then checking my TA it was only at 60ppm. But of course when I add baking soda the PH goes up - this is a never ending battle!! I am going to check the spa tonight and see where I am at and post it on here.

Thanks for puttong the 80's song squarely in my head for the rest of the day!!!!!!

Richard nice response. I have another question for you. Di-chlor is not cheap if you get the 99 percent pure stuff. A salesman at the pool place told me I could use the 60 % stuff for the spa - is this ok? Whats the other 40 percent made of - will that clog my filters or cause other issues?

yeah and the speed limit is 55 too! you shouldn't do a lot of things but if you have some brains you can get away with some. I think I could sit in a 103 hot tub for an hour and not get too hot! If it really was 104 Iw ould be fine but the trigger is at 103 so really they should set it at 105 so the trigger would be 104.

Well the link says over 110 is dangerous. So you would think 105/106 is no problem. Bascially I liek to get in and once I start feeling hot I sit out of the tub. I just repeat this process until i am done and usually never stay longer then 30 minutes in the tub. But right before I get out i like to get deep in the water and really heat up - then I get up and feel nice and woozy for bedtime!

Ok so there is a way - I didn't ask for the "smart" answer. I'll do it myself if someone can show me. But yes I know the dangers of the hot tub getting too hot - but as long as you have a thermometer in the tub you check before getting in you should be ok. All I want is 105/106 - 104 just does not cut it for me. And I really don't think it stays at 104 since the therm turns off at 104! I figure I can't be the only person who thinks that 104 is too hot.

Thanks for the in depth response! Surely some elcetrical hacker has the ability to do this - I am no electrician but you would think there was a way.

Ok I have a 2002 D1 Diplomat. does anyone lnow if there is a way to tweak the equipment (thermostat, etc...) so that you can heat thue tub to 105-106. The problem is that 104 is not hot enough - plus once it gets to 104 it stops heating and does not heat again till it goes to 103 - but at that point the tub is not hot enough anymore. This is not so bad in the summer but will cause me a headache in the winter. When I get out of a hot tub I expect to have been heated up to a point where the outside temp does not bother me and the heat lasts till i get my robe on and head inside. If I get cold immediately after stepping out of a tub then its not hot enough. Any advice would be helpful.

Dealer has quoted me 8K for Aurora II with lift, 9300 for Diplomat.

anyone have more thoughts. I am wet testing the tub today.

Hey guys I just found the seller who owns this tub he is going to sell on consignment at the dealer. I randomly found him while searching review on the net. He had an add on craigs list - asking 6900 for the tub. Of course if i buiy used from him i won't get any warrant y at all but I could save over 2000 dollars. I would probably offer around 6-6500 for the tub and assume about 500 bucks worht of delievery. My gate is small so then may need a crane. So what do you guys think. I could save a lot of money here on a used tub. THe guy is going to filll the tub for me and let me try it tonight or tomorrow. I will report back after testing it.

Hi Roger thanks for the input. They don't have the used one ready for wet test - but they have the same model in the store to try out. She told me nothing has changed from 05 to 06 for the most part.

This is a great priced tub. I like the deep seat lounge as well. Anyone have thoughts on this tub that would help me out? Also they use UV ozone rather then CD - does that make a difference?

Hi guys - I posted this in another forum so sorry if some of you read it twice - but it seems as there are more D1 people on this forum. So the d1 dealer has this lotus bay on consignment - she will give it to me for 9K out the door. Now it is a used model (05). But she said the "store" will warranty the item for me in writing for 3 years (store has been there for 20 yrs under same ownership). She told me its a 12K spa and one of the best out there. And of course she said it would be gone soon so I better move quick if i want it. I will leave it at that - so if there are any D1 dealers out here please let me know if this is a good deal or not.
