Ex- i have my pool & my hot tub
Something to add here. If you use sodium bromide in conjunction with liquid chlorine your pool will clear much quicker. Also make sure your ph is in check. If your PH is getting high especially after adding liquid bleach you need to keep it at a lower level (7.0-7.4). Lower the ph the more effective chlorine is. Also your filter needs to be cleaned after every algae issue. Thoroughly. If you get a container of sodium bromide and add it before the liquid and brush the pool thoroughly first (skimmer box, around the light ring etc). If you miss even a tiny spot of algae it will come right back. And get your PH on the lower end (6.8-7.2). After adding bleach it will come back up anyway. You may be playing whack a mole with your PH and alkaline levels... it's easy to do. run the pool minimum 24 hrs and it will clear. Make sure phosphate levels aren't out of control. I know phosphates here are a taboo subject but phosphate levels when extremely high do cause issues. I've seen it many times. I'm talking extra high levels. Outdoor pools seem to get it way more due to organic matter. Best of luck. A small bit of clarifier after will also help with the dead algae being filtered out. And restore clarity. Then after 24 hrs clean filter again. Just my 2cents here. Almost every place I go to with recurring algae either salt water or not, the filter is the most overlooked ingredient. Also places algae hides that u don't see. Skimmer box is a big one. Also lights. Handrails or step ladders. Try some sodium bromine though. It will turn the pool a Mountain Dew color for a min but that's normal. It essentially makes chlorine on steroids. Weather or not others agree with me is fine. Just coming from a company that services 1,077 pools a week.......
Also I know sodium bromine is better for high cy issue type scenarios but it seems like this is a recurring issue. Just thought maybe a different approach may help with better results. I'm Probly gonna get jumped on for it but I have done thousands of green to clean pools in my life and the SB approach just works. If nothing else is working try different Approach. Best of luck. Also been using borates recently in some pools. Stuff is kind of a forgotten gem. It can absolutely help with problem pools. That's a whole different thread though

I would not recommend sodium bromide. You will eventually end up with a bromine pool.
Just follow the SLAM Process.
The problem with bromine is that it is not protected from UV by CYA. This may sound appealing while dealing with an algae infested pool at high CYA levels, as you will get high levels of hypobromous acid without interaction with CYA.
The problems start when continuing with normal pool operation after the algae has been cleared. The bromide remains in the pool. Added chlorine will oxidise the bromide into bromine (hypobromous acid), which is then the active sanitiser in the pool. Bromine is very unstable under UV light, and the bromine bank will get depleted very quickly. You'll end up with a very high chlorine demand, the next algae bloom is just a question of time.
It is much better to deal with high CYA first, then follow the SLAM Process.
