I recently added a SWG to my above ground pool. I followed the instructions and added about 50lbs of pool salt to my pool and ran the pump overnight. Prior to adding the salt there was no signs of algae in the pool. When I checked the pool in the morning algae had appeared (SWG had not been running at this point). After 24 hours I started the SWG and ran it in boost cycle to "shock" the pool due to the algae. The algae didn't go away on its own. I took a trip to the local pool store and my water readings are below. They said the algae was most likely mustard algae and gave me a sodium bromide chemical to get rid of the algae.
FC: 12.35 ppm
TC: 12.35 ppm
CC: 0 ppm
pH: 7.6
Hardness: 144 ppm
Alkalinity: 121 ppm
Cyanuric Acid: 48 ppm
Copper: 0.1 ppm
Iron: 0.1 ppm
Borate: 10 ppm
Salt: 3800
My questions -
1. How do I get the FC level down? Will it naturally come down with normal operation of the SWG after my initial boost/shock of the pool?
2. I added the Sodium Bromide to the pool after scrubbing the algae (it easily came off) and vacuumed the bottom of the pool. What do I do now? Do I give it a day or two and see if the algae returns, do I keep adding more sodium bromide in 24 hours?
3. What possibly caused the algae and how can I prevent it in the future?
4. Any additional advice/comments regarding my #'s or anything in general would be greatly appreciated.
Thanks!
