Vegas

Ph was never low always 7.6-7.8 Sanitizer always in range 2-5ppm

What chemistry in particular? water is tested at Leslie’s and my Taylor drop test kit

Found it! O-rings were breaking down. what could cause this?

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.

More Pics of the filter

Odd it shows on my end, it’s a video. Let me go take a few photos and post those

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

Thank you

if you go back and read my post I’ve already done that Furthermore the tub didn’t sit with water in it the pump was replaced immediately

One of our tubs pumps went out and the dealer replaced the pump under warranty. A few weeks go by and I started Black dots at the waterline on the shell. Pull the filters same thing. When trying to wipe off this black it would just smudge and I would have to use a good amount of pressure to wipe it off the shell. Figured it was some sort of contamination I dump the water and refilled. Almost immediately the black spots reappeared but even worse on the filters. I purged with ahh-some. Bleached the entire shell and cover, rinsed very well, Refilled and super chlorinated the water. Allowed the water to circulate for 45 minutes at 20+ ppm then dumped the water again and put in brand new filters. I balanced the water and went back to chlorine as I never had these sort of issue with it. I also hit it with an enzyme and MPS ( 2ounces ) after I balanced. Now each morning I come out I find a bit of yellow/orange slime on the shell. ( did not take a picture) My suspicion is that the techs used a pump that was contaminated and allowed mold to form. But I also have zero experience with mold so I cannot confirm this is the issue. photo of water below is from when it was being Super chlorinated. Filter picture is after I allowed them to dry out in the sun. Any thoughts?

Thank you very much! That was a lot of information I did not know

The reading I posted is directly from Leslies Pool store. I was doubting my Taylor drop test key due to the high bromine so I had them test.

I Recently started using bromine in my tub and I’m having an issue keeping the Alkalinity in range between 80-120ppm. This is my second fill with Bromine after using Chlorine for a year and a half. I never had this issue when using Chlorine. Little background on the tub. 400 gallon,city water, ozone, circulation pump. Fresh fill with new filters, bromine salt to build the base, 2 oz MPS, 2 bromine tabs in floater. procedure was after the Water fill. I used dry acid to bring down the pH to 7.6. ( 4 ounces in total ) I then added the bromine salt, the MPS, and the floater. Ph then shot up to over 8.0 added another 3 ounces and then decided to take in a water sample to the pool store currently the reading are: 8.0 ph, 62 Alk, Calcium 158, Bromine is 8.42 Now I’ve read in this form that keeping alkalinity between 50 to 60 is not a problem. However of course everything were taught says the alkalinity should stay between 80 and 120. what’s your thoughts on my next steps bring the pH down and not worry about the alkalinity? or fight the alkalinity and pH to get them in traditional ranges?
