  1. Thanks HHT! You have calmed my nerves. It clears even faster now, in about 30 seconds, now that I have added a bit of clarifier. I am not getting any foam only the fizz with jets and air.
  2. What can you do to clean Biofilm if you have it?
  3. Brought Alkalinity up to 110 and added some clarifier last night. This morning water was as clear as new. Turned jets on full and fizzing started again and water goes cloudy. Turn of jets and it does clear much faster now. Its not the end of the world, not going to spend much more time on it but just curious as to what causes this. I guess I will wait till next fill and watch when it starts to fizz again.
  4. The same thing happens to me about 3 weeks after I change water. Water chemistry typically looks good. I figured this was typical? Same thing happened to me. I have a fresh fill about 3 weeks ago. Used 2 pre-filters inline. And used the pool calculator to find best alkalinity. Started at: CH:200 AL:220 PH:8.3 Now at: CH:200 AL:90 PH:7.8 Borate:50 CYA:around 30 now using 6% bleach and occasional MPS shock when I find chlorine demand is getting too high. I'm not sure exactly when the fizzing and cloudy water with jets on started, and I'm tempted to drain and start over. I think it may be due to using too many balancing chemicals and too high initial TDS or just excessive usage (only had tub 2 months, this is the 2nd fill). Water is clear when jets are not on but then something precipitates out of the water with jets on. I've ordered some Sea-Klear to see if this will cure it. Will let you know how it goes. If it doesn't clear it up then the next fill will try using the water softener from the house and starting with a lower CH. I read somewhere that calcium can precipitate under certain conditions? Put more thought into this and i've not tried the Sea-Klear yet, it will take another week to be delivered, but I don't think a clarifier is going to help. Our town water is known to be notoriously hard. I think I will drain and refill with soft water so I can then hold a higher alkalinity and still have balanced water (due to lower CH) and then the higher alkalinity should stop the fizzing/cloudy water with jets on. Foaming or fizzing can be a sign of a bacterial biofilm contamination. When spas are free of biofilm and the water chemistry is in balance, the water will be clear and foam free. Bacterial biofilms are everywhere in our enviornment when water and a surface come together. Hot tubs are the perfect opportunity for biofilm formation because bacteria love temperatures of 98 dgrees or higher. Once biofilm is formed, sanitizers in normal dosages do not penetrate them leaving up to 99% of the bacteria present to remain active and multiply. This understanding of biofilm and how to treat it is important because scientists now recognize that more than 80% of water management issue are biofilm related. You can learn more about biofilm research by going to Montana State University's Center for Biofilm Engineering's web site at http://www.erc.montana.edu/. It appears as though Combined Chlorines can result from biofilm contamination. I read some on biofilm and i don't think this can be my issue. my tub is only 2 months old. I checked Alkalinity before increasing it and it was not 90 like I thought it had dropped to 50! Bringing up the Alkalinity slowly will see if fizzing/cloudy water (with jets on) starts to disappears. What is the difference between Alkalinity increaser Ph increaser/baking soda? Alkalinity increaser will raise alkalinity and not Ph? and Ph increaser/baking soda will raise Ph and Alkalinity as a result?

On day 4 and 5 day of fresh fill I didn't add my dichlor (because dealer said I wouldn't have to keep it always above 0ppm because of MPS) and tub went cloudy (without jets) I got it back by shocking and then found this forum and switched to bleach. So maybe biofilm was created and still exists in tub. So the tub can be crystal clear before getting in and still contain biofilm? I'm going to try increasing Alkalinity tonight from 80 to 100 to see if it changes fizzing. If not I will refill this weekend.
