Is it possible to get mustard algae and have your pool look crystal clear and pool chemistry stable? I have a 31,500 gallon pool and my chemistry readings are consistently as follows:
Every night I test and add 12% liquid chlorine to get my FC up to 6 which I have as my target FC. My problem is that I have noticed that I have mustard algae forming in the pool which is very confusing to me. It looks like I will have to SLAM my pool this weekend to get rid of it but I don't understand how I even got it in the first place since I have been faithful in testing and adjusting. Any help would be appreciated.
