Welcome to our forum.
WE use enhanced shock or lithium hypochlorite as a shock agent.
Let me just start by saying that after 30 years in this industry, I have never seen so many complicated responses...And if this is what potential customers think of water chemistry we might just as well start selling something simple like nuclear energy! ....
I think it is unwise to take a captive audience, whose sole purpose is to help people with their problems (that is what we try to do) and say look at the problems that we have seen.
...One final note is that some number of rash/itch reports were apparently due to things like the jets being too strong or those with more sensitive skin, so it's not just bacterial nor chemical sources of irritation, but physical ones as well....Richard
I've been dumping in a couple teaspoons of dichlor after use, shocking with a couple tablespoons of dichlor for a shock or a few ozs. of MPS after 8-10 soaks for 10-15 years!! Always had crisp clear water. Never had a bacteria problem. Drained every 3-4 sometimes 5 months depending on how much use. Imagine my suprise to read this thread and find out it wasn't right!!! Now what do I do?
Richard,I disagree with the N2 or Frog people and the ozone effect. They do work somewhat but silver works slowly so I question how effective silver is in a spa situation and spa/pool ozonators can only inject so much ozone with air being at 21% O2. With my own tub, N2/frog and ozonator (which is a very small sample) I have not seen either work well. It could be my water, my tub design, my ozonator or me. My experimentation on my own tub showed that N2/frog and ozone give me 1 extra day of clear water (4 days vs 3) but clear water doesn't equal clean tub. I've tried the N2/frog on 3 separate occasions. I can actually get clear water sometimes just from dichlor for 4 or 5 days as well.
