Welcome to our forum.
Ken,I am very new to the water chemistry game. We have had our Jacuzzi (approx 375 gallon capacity)hot tub for approx 2 months, and use bromine as a sanitizer with weekly MPS shocks. Until 2 weeks ago I used a 2 part bromine system. The MPS is unbuffered pool shock.I find I have been able to maintain crystal clear water for approx 6 days a week. Usually the last day the water will have a a very slight haze to it. The tub is used daily (2-3 people) and there is usually one multiple (4-5 hours) hour social that occurs on a weekly basis. The users generally do not shower before entering the tub.I have found that adding sanitizer a couple of hours before the weekly social will help keep the water clear. On a weekly basis I add 2 tablespoons of the unbuffered MPS and run both pumps for approx 1/2 hour. I then add some alkalinity increaser with the goal of keeping alk at 120 ppm. I also check that pH is in range. I then add approx 2 tbps of polymer and run all pumps with air injection for approx 40 minutes. There is usually some "sludge" along the water line that needs to be removed. I then switch-out the filters. The water remains crystal clear for the next 6 days with daily sanitizer addition.As stated above, approx 2 weeks ago I switched from the 2 part bromine system to a combined dichlor and bromine sanitizer. Results-Water clarity has been very good and the system is easier to use. Hope this helps.Dave
This is a subject about which I am still cloudy after a number of years as a spa owner. Why do we need to SHOCK at all? There must be someone who can provide a reasonable explanation. I'm all eyes.
Shocking is a term that seems to be mis-used alot on this forum. I have seen it used to describe sanitizing and oxidizing. Some products like dichlor can be used both to sanitize and oxidize, it just depends on the dosage rate.Hope this helps;HotTubMan
Thanks HotTubMan. From your post, it seems I still need to "shock" periodically. How do I shock vs "toss in a small amount of dichlor after every second or third use? What ppm of dichlor gives me an official shock to the tub?
