Mixed Chemicals = Cloudy Swim Spa / Pool

[milhouse19]

NOTE TO ALL: This poster's pool is INDOORS and is functionally a SPA, not a POOL (95 degrees year round). The standard advice we give here does NOT apply!

I have a 3000 gallon (indoor) Endless Pool which has been stable for about 2 years using Chlorine. I recently had a part replaced that required draining about 1/3 of the pool (this past Saturday). After filling it back up, the balance was off and the installer added PH raise and Alkalinity raise at the same time. Then as he was leaving he added a clarifier. 6 hours later when I take off the cover it was completely cloudy with maybe 18" visibility and a slightly green tint. I don't think the cloudiness was caused by anything mechanical (Endless Pools just use a cartridge filter which wasn't changed and 2 Nature2s which were replaced), but I can't be certain.

After talking to a (different) pool professional, he told me to shock the pool which I did on Sunday.

As of this morning (Wed.), its still cloudy. All pool levels are ok (PH is a bit low, but not terrible) except for Chlorine which is so high its off scale., The cloudiness may have slightly improved, and it looks more blue than green, now, but really its not much better. I ran the filter for about 12 hours yesterday.

If it matters, since its indoors, it doesn't get a lot of sun so I haven't been able to burn off the Chlorine. Also, the pool is kept around 95 degrees since its for my wife's therapy.

Any suggestions on how to clear the pool? I don't mind waiting a few days, but its been 4 now and there has been little improvement. If I have to empty and refill, I'd rather do it sooner than later. I'm also worried that the chemicals will damage the liner - I've already had issues with Endless Pool liners.


Unrelated, I am thinking of switching from Chlorine to Bromine if I have to empty and refill, but would like any input on whether that's a good idea. The itchy skin and destroyed bathing suits are taking a toll, plus I understand Chlorine works best around 75 degrees, while Bromine works better at higher temperatures.


Thanks
