Background: I am a dealer and ardent supporter of sticking to the basics of water chemistry: Maintain pH, alk and sanitizer levels and generally speaking you'll do fine. Approach any issues on a per-case basis and don't take advantage of the customer by selling a lot of extras that aren't *needed* unless they insist on it.
Issue: There was a run of bad ozononators a while back that had oil in the ozone line. Every spa and swim spa in question had their ozone and ozone line replaced, plus we added to each tub several gallons of vinegar to the water to eradicate the fizzy, foamy water (the byproduct of the oil in the line), then drained the tub, cleaned it, refilled and replaced cartridges. Every spa was fine after that. Except for one...
This spa continues to show the same issues: Water is clear, jets turned on, minor foaming and when the jets are turned off it fizzes and takes approx. 5 mins to clear up. We have repeated the process explained above and the customer has been thoroughly vetted on several occasions to ensure they are not doing anything to discourage the process. Still no resolution.
Action: We have gotten some free samples of Aqua Finesse from a rep that was passing through the area (I am thoroughly aware of what that product is, what it does, and what it doesn't do) and have looked up Aqua Finesse threads on this forum before I posted this to get better educated with outside opinions. I plan on using the free samples given b/c what the heck do I have to lose? Additionally- I have sent a water sample off to our chemists to see what is going on and to get their feedback.
Question: Has anyone had this issue? If so, any recommendations? I don't want to continue to lose money via service calls and chems that I am sinking into this customer, who has been a trooper throughout the process. But as we have a reputation to maintain it has to be done. I just want to expedite the process.
Thanks for reading and I look forward to some feedback.
