Vegas Posted February 2, 2023 Report Share Posted February 2, 2023 I posted quite awhile back about black flakes in the tub. I was told re-run ahh-some through it again. Well I have done that as well as 2 other purge products and have in total drained and refilled 6 times. And super chlorinated once just in case it was mold. Here is the background: purchased tub in 2020 NEW. Black flakes started appearing around the water line and in the filters right after a pump went out and we had it replaced under warranty. This is when I started purging and refilling thinking it was either mold or some sort of contamination with the pump. Also at this time we had switched the Bromine ( with a floater ) after all my attempts at to fix the issue the dealer agreed to replace the pump once again, as well as the circulation pump as it was leaking. They also asked us to switch back to chlorine which, I did so. Well after a week with the new pump and fresh water the black flakes are back. I believe they are rubber degrading or some sort of coating used internally due to the fact you can’t really catch them. When you go to wipe it off they smudge like ink. as far as balancing the tub I have always used a Taylor Drop test kit AND take sample to my local Leslie’s. Tub also has an ozone. I have added a short video of the filter for reference. I really appreciate any help you all can offer me!! IMG_0299.MOV Quote Link to comment Share on other sites More sharing options...

CanadianSpaTech Posted February 2, 2023 Report Share Posted February 2, 2023 List what external products and chemicals you add to the spas water. As for rubber in a spa you have 0-rings around the control valves on the top edge of the spa. O-rings sealing plumbing to pumps as well as to the heater tube. The heater tube gasket type O-rings can decay a little quicker and worth a check. O-rings/gaskets around jet bodies sealing the jet to the acrylic. Gate Valves or slice valves also carry a rubber plunger to shut off or isolate components from water like pumps or the heater for repair. What is the source of the water you are putting into the spa? Do you use a mineral stick or the @ease frog system? Quote Link to comment Share on other sites More sharing options...

We use Las Vegas tap water chemicals are: Leslie’s Dry Acid, baking soda. as needed leisure Time, chlorinating granules. leisure Time, nonchlorine shock. spa perfect enzymes once a month. we DID use a drop in mineral stick when we first purchased the tub but stopped That’s it.

Jay G Posted February 8, 2023 Report Share Posted February 8, 2023 To be honest, usually bad water chemistry. But since your tub is so new..... maybe they got a bad batch? Quote Link to comment Share on other sites More sharing options...

I just know that every time I read about rings degrading, it's the chemicals they are using. Quote Link to comment Share on other sites More sharing options...

They aren't in the business of selling you the most efficient economical easy soak. Their advice is generalized and not specific to any one spa. That's why it's always advised to take the advice of the manufacturer or dealer over these pool supply stores. Quote Link to comment Share on other sites More sharing options...
