I had white water mold when I opened my pool april30,2018. Local pool company had me use sodium bromide. The its night I did 6 lbs followed by 12 gallons of chlorine, the next morning 4 gallons of chlorine. I did this for 3 days. Went back to the pool store water was cloudy and no free chlorine. When tested they had me do the same process for 2 more days. That was a total of 10 lbs of sodium bromide for a 27,000 gallon pool. It is not almost thirty days later and I have no total or free chlorine the reading said-5.0 of combined. I had partially drained the pool as well. The water is crystal clear but I still can't keep free chlorine. I am so frustrated and I don't know what to do. Do I know have a bromide pool? Is this the reason I see no free chlorine and if so what do I do. I drained it half way and refilled. I have used get this 100 gallons of liquid chlorine and many pounds of powder. I have spent at least 800 dollars on all these chemicals plus phos away etc. please help. Thanks

Reason: By the way this was99 percent sodium bromide
You might want to take a sample to another company or get a pool company come out and get your pool in balance.
Stop draining your water. You can get the existing water in balance with the proper help. Find a reputable pool cleaning/service company to come out and check all your levels of chemicals.
I'll refer you to troublefreepool.com. First step in getting control of your pool is to get your own test kit that's capable of measuring stabilizer (CYA) and FAS-DPD. Typically either the Taylor K-2006 or the TF100 test kit. Either way visit troublefreepool and I guarantee if you follow the steps outlined there you will truly control your pool. GL
Switching to salt is a long term resolution. Short term, if you are having that much of a problem, hire a pool guy to get things into condition and keep it stable. Unless changing modalities from Chlorine or bromine to salt, draining the pool is exactly what you DON'T want to do. Pool water is a soup of chemicals. Throw that water out and you just have to remake the soup.
Salt is only another method of chlorination. It is not something I would call a long term resolution outside of the fact that you generally don't get the higher stabilizer levels that plague many people. In general your pool water should not be a "soup" of chemicals. The only things that should exist as permanent fixtures of "chemicals" inside your pool are CYA (Stabilizer), chlorine, calcium, and salt if being added either manually or through additions of liquid chlorine. It may very well be necessary to drain if your stabilizer levels are too high. This is the only way to remove the stabilizer and get to a point where you can manage the chlorine level to a point to kill the algae in your pool.
My understanding is that white water mold is a biofilm, so you have to mechanically clean the pool and add a LOT of chlorine to kill it. If your free chlorine keeps going to zero, something's destroying it, either UV (from not enough stabilizer) or algae and fungi.
