Rom Lokken Posted August 20, 2021 Report Share Posted August 20, 2021 Hi all, New tub six weeks in. Tested daily (for my own education) with Taylor drop kit. Using nature2, has Ozone and UV, Spa marvel and maintain a daily chlorine level of 1-3ppm (1/2 tbsp per bather per hour). MPS weekly or twice weekly when heavily used. Free Chlorine and Total Chlorine are in lockstep. Ph is rock solid at 7.4. Alkalinity is 120. Prefilter is swapped out and washed weekly. Filter is sprayed weekly, swapped out and soaked monthly. All good so far. Water is clear. Water stays clear without jets on low. Full jets and full air produces a slight foam that dissipates quickly but produces what appears to be slight oil slicks. MPS shock doesn’t change this. SuperChlorination didn’t either. Total dissolved solids are only at ~750ppm. So any idea about how much foam is normal and if some oil is uneradicable? Thought?

Frank B Posted August 20, 2021 Report Share Posted August 20, 2021 I’m only a week or so in but experiencing the same. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted August 20, 2021 Report Share Posted August 20, 2021 Most foam is from stuff you bring in. Fabric softener/detergent residue, lotion residue, hair conditioner, makeup, etc. Enzyme products break these down and defoamer hides the problem, but it is best to eliminate the cause.

Rom Lokken Posted August 20, 2021 Author Report Share Posted August 20, 2021 RDspaguy I have no doubt WHERE it came from. But we shower before entering, have thoroughly rinsed bathing suits and I’m already using enzymes. And yet there’s still this slight foam (very slight) on high. Since I’m a newbie I’m wondering what’s normal. I’m not by my spa but I’ll add a picture of the issue. Quote Link to comment Share on other sites More sharing options...

I’ve now added a series of video for reference. Clear in the first (the videos are out of order but obvious) with only filtering jets. Slight agitation on next setting. Foam on high jets full air. Quick dissipation. Followed by slight bubble/oil streaks. Since I’m a newbie I’m wondering what’s normal.

RDspaguy Posted August 22, 2021 Report Share Posted August 22, 2021 Your images are unavailable. Sounds like you are covering the bases. I'm not sure what else may be the cause. Quote Link to comment Share on other sites More sharing options...
Ahhsomeguy Posted August 23, 2021 Report Share Posted August 23, 2021 Hello ROM Lokken: Have you done a plumbing purge to get rid of any biofilm or bio-contaminants? This should be performed even on brand new hot tubs that have never even been used. 1 Quote Link to comment Share on other sites More sharing options...
Rom Lokken Posted August 24, 2021 Author Report Share Posted August 24, 2021 My dealer came over to set up the hot tub the first time and I thought “ok, let’s see how this goes”. Frankly, they seemed to do everything wrong. I’m going to empty soon and do a proper purge. Quote Link to comment Share on other sites More sharing options...
Ahhsomeguy Posted August 24, 2021 Report Share Posted August 24, 2021 Don't empty the tub before you do a purge. Why waste water? Purge now with the same water. 1 Quote Link to comment Share on other sites More sharing options...
Rom Lokken Posted August 24, 2021 Author Report Share Posted August 24, 2021 That was my intent. I’ll do the purge before the water change. but interestingly the slight foaming has largely subsided. I had upped my sanitizer baseline and that seems to have tackled the problem. Quote Link to comment Share on other sites More sharing options...
Ahhsomeguy Posted August 24, 2021 Report Share Posted August 24, 2021 To be sure that the nasties are attenuated we strongly recommend that you purge. If you think the maintenance is easier now it will be even easier after the purge. Quote Link to comment Share on other sites More sharing options...
