New to hot tubs, just got a used one up and running with no leaks. So it's been ok for a week and a half now. I've been using a bromine floater, and just today I checked the pH as usual it was very low, so I added a bunch of pH up (sodium carbonate) and waited a while, checked it, added more, waited, checked again, and added a bit more, and all of a sudden the water turned cloudy white. So my question is: will this clear up or should I drain it and start fresh, and dump the bromine for Dichlor, and get new test strips (I think the old ones are a few years old and may not be working correctly)?
Any help is appreciated!

So... it turns out my old test strips were not good anymore (maybe some moisture got into them?), and I had brought the pH up way too high- above 8.5, and the calcium precipitated out of the water (0 calcium hardness according to the new test strips). As soon as I got the pH down to a reasonable level with sodium bisulfate, and I stirred all the calcium up off the bottom, the calcium hardness went back to normal, and everything is fine.
