http://www.cwsnaturally.com/spa/Check out that nasty bio-film! ...I have never incurred biofilm in nearly 40 years of continuous spa ownership and I use very little in the way of chemicals (usually $3-$6 per month). By following tried-and-true water chemistry/sanitation methods, I have enjoyed trouble-free spa use. Although I am open-minded, I am very weary to scrap something so simple and effective for the latest "new and improved" thing.

Me too, but they used it in a very large pubilic pool not far from my house and it worked like a charm. And my spa gal says it may be possible to go a year between fills. But, she also sems skeptical. I may try it for fun and see for myself. Was just hoping others may have tried it already.

There's another sphagnum moss product talked about in this thread. Unless the moss catalyzes oxidation of urea and ammonia (from sweat and urine), you're still going to have a rough oxidizer demand where every person-hour of soaking at hot (100-104F) spa temps will require approximately 3-1/2 teaspoons of Dichlor, 5 fluid ounces of 6% bleach, or 7 teaspoons of non-chlorine shock (MPS) to oxidize the bather waste. There are enzyme products that can reduce chlorine usage, but as Nitro points out the cost of Dichlor-then-bleach is so low already that one must question why such extra-added products are necessary. The Nature2 plus (mostly) non-chlorine shock (MPS) is another approach that many are happy with. And, of course, there is bromine which lets you have a bromine feeder for less maintenance since the dosing is more automatic. The main thing that the sphagnum moss products don't talk about is how planktonic (that is, free-floating) bacteria are killed extraordinarily quickly when chlorine is present so the best way of preventing biofilm formation is to kill bacteria before they can form significant biofilms in the first place. If you are the type that can't or won't maintain sufficient sanitizer levels almost all of the time, then products such as Nature2 can help and maybe this spagnum moss product might be of some use.

Although I am open-minded, I am very weary to scrap something so simple and effective for the latest "new and improved" thing. I believe in the saying that "if it ain't broke don't fix it" so if your method is working keep at it. I would beg to question you about never having biofilm. Scientist will tell you that bacteria and biofilm are every where in our environment. Did you know that the tarter on your teeth is a form of biofilm. Have you ever had the ring around your spa at the water line? Have your ever had a calcium build up on the spa surfaces? Calcium is not sticky so then what is it sticking to? Have you ever had a foamy spa? Red eyes, dry skin, unpleasant odors caused by chloramines? How about water clarity issues? The chances are that 80 to 90% of these issues are biofilm related. Check out this website; http://www.erc.montana.edu/The spa manufactuers begin the contamination process when they wet test every spa they build. Even brand new pumps and heaters are wet tested. The brand new spa shown on our website wwwcwsnaturally.com had never been used when we flushed it for this video. The spa company now uses our system in their plant that has led up to a 90% reduction in biofilm formation. This "new and improved" thing has been treating water for centuries in Northern Minnesota and Southern Canada. The Vikings stored their food in it for long voyages. The Native Americans used it for wound dressings and to pack their babies in. The Red Cross harvested it in Minnesota during WWI to use for wound dressings before the invention of antibiotics. Pathogenic bacteria, the majoity of whom live in biofilms, still kill 500,000 people in the US every year according to a July article in Discover Magazine: http://discovermagazine.com/2009/jul-aug/1...earchterm=SlimeThis species of sphagnum moss is nature's way to treat water and is the only truly "green" option in this industry. It is amazing how it effects water quality while reducing the work it takes to care for your pool or spa.

No. To elaborate/qualify my above responses...with nearly 40 years of spa ownership...with proper water maintenance...with established tried and true sanitation methods...with absolute minimal introduction of external detergents, fragrance, antiperspirant, etc. products, I can say I have not had any biofilm issues of any significance or concern. In fact, this is self-evident that I am still here and can attest to not incurring such alarming waterline rings, calcium build-up, foam, red eyes, dry skin, unpleasant odors or water clarity issues of any importance (all mitigated through conventional proper water maintenance [assumption]). Regardless, if your purported product (read assumed hidden agenda) is the next advancement in spa water maintenance...I will keep an open (but cautious) mind.

Looks like Spa System Flush can be purchased separately so if it's a superior cleaning product for a new spa then that could be a good choice. By the way, there is a Spa System Flush that was recommended on this forum as far back as 2005. It would be interesting to compare the two. It looks like Spa Purge may be not as effective. I'll be interested to see the 90%, or even any significant, reduction in chlorine (oxidizer) usage claimed by SpaNaturally. What kind of sanitizer/oxidizer method do you plan to use? Will you be using chlorine? If so, will you be using Dichlor-only or starting with Dichlor and then switching to bleach after cumulatively using around 33 ppm FC of Dichlor? Will you keep the spa water hot (100-104F)? Will you soak every day and if so, for how long? I look forward to seeing your results. Since those using the Dichlor-then-bleach method have clean clear water that lasts for 6 months or more (and is still crystal clear at that time), the main benefits would be a potentially superior initial cleaning using Spa System flush ($20) and maybe reduction in oxidizer usage (remains to be seen). It might also be insurance to inhibit bacterial growth if the chlorine level gets too low, similar to Nature2, though that remains to be seen. Each refill package of the moss is $17 and for most spas (< 450 gallons) it is one package per month so it had better do something significantly better than simply maintaining a sufficient chlorine residual at all times.

I'd be willing to bet these are both the exact same product. Just one has a label glued onto the bottle and is twice the cost. This is based on the bottles being the exact same shape, and the name "Spa System Flush" being a trademarked name.

In one of my spas, I use the Spa Frog yellow (Bromine) and blue (Mineral) cartridge float system. I buy in-bulk and on my last purchase I paid approximately $80.00 for 9 Bromine and 3 Mineral cartridges. Doing a little algebra based on market observed dependent ratios between the two cartridge products...I believe the approximate unit cost for this given purchase was $4.99 (Bromine) and $11.68 (Mineral) per cartridge. Further, my last bulk purchase of 43% MPS cost approximately $128.00 for 50lbs...which relates to 6.25oz per $. My observed monthly water sanitation costs: Bromine cartridge is replaced when expended; for me, it typically will last 3 months with an orifice setting of "3" tethered and floating mid-way between active filter-cycle jets (the manufacture states the cartridge will last 2-4 weeks which is way below my observations). = $1.66 per month. Mineral cartridge, per the manufacturer's instructions, should be replaced every 4 months (I have gone 6 months with no ill effects). = $2.92 per month. I typically use not more than 2-3oz of MPS per week (CD ozonator; *sanitizer target: 1ppm [+/-0.5ppm]; 420 gallon [as filled]; 100F; 1-or-2 people at 20-50 minutes 3 times per week; *1hr/12hrs filtering cycle)...or approximately 10.75oz per month. = $1.72 per month. Total monthly cost to maintain sanitizer levels with Spa Frog: $6.30. Note: This price is dependent on discount out-of-state bulk purchases with nominal shipping charges. My wife and I travel, so I rely on the proven 3-step Bromine system because it is very simple, somewhat cost effective and keeps my water crystal clear and odor/irritation free for 4-to-6 months between fills. In fact, I used only 2oz of TA+ and 1oz of pH- over 5 months between refills to maintain water balance. * I maintain my spa's sanitizer levels and daily filtration cycles below recommended minimums (3-5ppm and 2hrs/12hrs respectively) with no ill effects to date. P.S. If my wife and I did not enjoy traveling so much, I would simply use Nitro's method...which I did (with some variation) for more the 10 years with no issues. I have been using some form of the Bromine 3-step method for over 25 years with no issues (other than somewhat higher costs, but arguably lower effort). P.P.S. Please let me know if there is a cheaper MPS way to go: http://www.poolspaforum.com/forum/index.php?showtopic=21724For reference (Nitro's methods): Nitro's Approach To Water Maintenance A guide to Water Balance and Sanitation using Chlorine http://www.poolspaforum.com/forum/index.php?showtopic=13634Lowering Total Alkalinity How to lower TA, without lowering pH http://www.poolspaforum.com/forum/index.php?showtopic=19149Chlorine Demand (CD) What is it, and why you should care http://www.poolspaforum.com/forum/index.php?showtopic=18706Decontamination How to Super Shock your Tub http://www.poolspaforum.com/forum/index.php?showtopic=19115

The Yellow cartridge is 150 grams while the Green cartridge is 200 grams; they are identical otherwise. SpaGuard Spa Shock is 31% potassium monopersulfate (MPS). The rough amount of 7 teaspoons of non-chlorine shock for every person-hour of soaking that I often refer to is for 43%, so 9.7 tespoons (about 3.2 tablespoons) per person-hour would be needed for this product. So your 3 tablespoons is 9 teaspoons for roughly another person-hour of soak time and you did this once or twice a week so let's say on average 1.5 times so that's 1.5 person-hours of extra soak time.
Your usage is 2 people 30 minutes, so one person-hour, 3 times during the week and 4 times on the weekend so that's 7 person-hours of soaking per week. The non-chlorine shock, as noted above, should handle only one person-hour so that leaves 6 for the cartridge to handle each week. Based on my previous calculations, that's only a little more than one week for the cartridge, assuming it dissolved that fast (which it probably doesn't, as you've seen).
Basically, you haven't been using nearly enough oxidizer. If the cartridge was just for maintaining a residual between soaks, then you would need to have it set lower and add about 3 tablespoons of non-chlorine shock after every soak. This all assumes hot 100-104F spa temps and "normal" amounts of sweat/urine and that no ozonator is being used.
Unfortunately, with a bromine spa it's much harder to know if you have fallen behind because all that gets measured is Total Bromine which includes bromamine. Bromamine is a sanitizer (unlike chloramine which is far weaker) which is why a separate Free Bromine reading isn't done. However, I suspect that in your spa that your Total Bromine reading is mostly bromamine and also have a lot of unoxidized urea.
So how did you figure on setting your cartridge to "4"? What happens if it is set lower? Did you set this based on some water chemistry readings?
I wouldn't do your test (with moss) by setting the cartridge to "1" -- it will obviously last a lot longer that way which doesn't prove anything. Instead, set it the way it was before at "4" and use the same amount of oxidizer you did before and see if anything is different such as the Total Bromine readings. Unfortunately, because not enough oxidizer was used, you probably won't be able to tell if there is any less need for it.

I watch eBay for killer deals and I rarely ever buy spa chemicals from my local spa shops (usually costing 4-8 times what I would pay buying in-bulk). First hit on Google brought up this deal for $104.50: http://cgi.ebay.com/Spa-Frog-Kit-12-pack-9...id=250524856919With this example...my cost wood be $1.43 higher per month.Keep looking...you can also find many bulk deals for the separate multi-packs for both the Bromine and Mineral cartridges which can further reduce your costs even more. Last year, I bought the following Leisure Time products (including the vacuum and net) off of Craigslist for literally pennies on the dollar...dirt cheap!

How big is your pool? And tey look like all kinds of different ones. I am tring to just stay with Bromine, Moss, and PH Decreaser.
